CPR R35 GTR Stage 4-5 Tuning - Engineer's Notes

2010-01-08T08:15:00.000-08:00

For our STAGE 4 tune the working brief was to achieve a strong and repeatable 600 hp 600 ft.lb which from initial study of the stock turbo spec, would possibly be the most we could reliably find from them. Well this is when the tuning of the GTR became both interesting and more involved than basic breathing add ons. The HKS panel filters were finding 10 WHP (additional power at the wheels) in the lower tuning stages. It was an obvious thought to us that a good improvement of air intake design would result in reasonable gains over the stock air box, as peak power was influenced relatively well by the basic introduction these HKS panel filters we thought it may be a restrictive area and worth a rework.

From the advance of gaining the Cobb Tuning PRO-ACCESS TUNER Software we are now able to 'live access' the GTR ECU during tune on our Dyno Dynamics AWD dyno and therefore gain valuable data logs of critical input signals from our previous stage tuning packages that work so well repeatedly exceeding target performance claims. More specifically data logs from output 'injector duty' and input 'air flow meter' signal on our STAGE 3 (using cobb generic tune) offered concerns as to the 'head room' left in these components to enable safe power increase. With this STAGE 3 generic tune running out quite rich in A/F ratio to mid 10:1 there would be room in the injector to find 30 -35 hp over our 580hp STAGE 3 with a more realistic and leaner target A/F of low 11:1. Unfortunately the same could not be said for the air flow meter signal as they would already reach their 'full scale deflection' of 4.9-5v in the 580hp STAGE 3. Therefore ANY increase in air flow over them would NOT be seen by the ECU and an accurate tune would be severely compromised at high load and high rpm!!

To gain headroom we chose to remount the stock air flow meter cartridge sensors into a larger body, therefore lowering the sensor voltage for a given total volume of air measured (Grammes/sec). Obviously correctly sizing this housing to allow the higher air flow and still be 'future proof' in further package development of higher power was critical. As the stock housing is the actual air box moulding we combined the development of our larger body housing into a full replacement induction kit, drawing air from the preferred forward area front panel so as not to pull ANY air from the warmer engine bay itself. To filter the air thoroughly, a cone shaped filter element was chosen to optimise flow in that given are which is in fact is capable of more than twice the flow of the panel / flat stock alternative!

With both these component limitations addressed we wanted to drop the total exhaust back pressure to a minimum and so the development of our replacement 3”front turbo outlet elbows allowed the removal of the more restrictive forward catalysts.

Time to see what increase in performance would come from these mods on the dyno, but first the critical rescaling of the airflow meter bodies was necessary to correct the ecu's interpretation of the now respectively lower voltage. This became a VERY technical necessity as side effects of getting straight into the tune would be extended to gearbox clutch control and calculated torque changes!

In our opinion there is only ONE way to skin this cat and it took time to build the file to support these hardware changes but the results were absolutely perfect, offering scaling to modify to an estimated 800hp!

Alternatively to this it is possible to buy the HKS 570 / 600 R kit which comes with NO ECU TUNE but chooses to interrupt the input signal and corrupt or clip its appropriate value. In our view and with our understanding of the side effects this technique causes at the transmission control unit (TCU) the age of corrupter and interrupter boxes have gone and should be left in the 'Nauties'. We would NEVER fit a Fuel Cut Defender (F.C.D.) to an '97 evo 4 , so why are their equivalent appearing on GTR's???

Back to the tune and it soon became obvious that the induction kit and turbine elbows combined had released far more power than expected, achieving over 530 whp but leading us to severe leaning out above 6000rpm at 15psi which we could not support with the stock fuel delivery! Injectors were flat out after 5500rpm with 17psi boost held up to this rpm offering 630+ ft.lb torque.

It became clear that this combination of hardware would need more fuel delivery on tap, so the introduction of larger 750cc/min RC injectors made safe this power level again with a comfortable amount of headroom in the injector for 800hp. Again the scaling of these injectors within the ECU is critical for its closed loop and target A/F ratio control to function accurately, amongst other side effects caused if this is not done correctly.

Alternatively, it is possible to use the same thought process as HKS used in their 600R kit and change the stock fuel reg to an adjustable unit to raise the fuel rail pressure and force more fuel through the stock injectors , which in turn, loads the stock pumps to the point they too must be changed for stronger units!! Again a very unprofessional approach in honest opinion!

This inadvertently became our STAGE 5 package but we found it necessary to add after market stronger sprung actuators to keep stable boost control. The lower exhaust back pressure limited the repeatable boost level at peak power and on back-to-back dyno runs the boost would fall dropping expected power at higher temperature. The after market actuators held consistent boost on repeated runs and deemed well worth the labour intensive fitments of them and earnt their place in this 630 hp / 630 ft.lb CPR STAGE 5 package.

Our STAGE 4 tune saw the emittance of the turbine elbows and the forward cats replaced. This corrected the boost control inconsistency and dropped power to the desired level that could be SAFELY supported by the stock fuel injectors. So we found our 600hp/ 600ft.lb torque package by essentially detuning the power found using hardware that is now our STAGE 5 630hp package!

Strange how things can work out!

With over 30 years of combined experience in the automotive wheel industry Forgestar Performance Wheels has bridged the gap between forged wheels and cast wheels. Forgestar Performance Wheels is proud to introduce the world's first one piece lightweight custom flow formed wheel lineup.

Flow Forming is a production procedure that turns the wheel (or rim section) over a special mandrel and three hydraulic rollers using tremendous pressure. The pressure and turning then force the rim area to form against the mandrel, creating the shape and width of the rim. During Flow Forming, the rim actually "flows" down to create the full rim width. During Flow Forming, pressure applied to the cast rim actually changes its mechanical properties, so its strength and impact values become similar to those of a forged rim. That translates to up to 15% less weight when compared to a standard cast wheel. Our technological breakthroughs in heat treating allow us to increase dent resistance without having to make the wheel heavier.

Forgestar Performance Wheels proprietary Flow Forming technology allows the customers to choose between a range of offsets for every wheel width that is offered. The end consumer is able to choose a wheel that will perfectly fit their own individual vehicle. All Forgestar Performance Wheels are compatible with tire pressure sensor monitors and allow clearance for most high performance brake caliper upgrades.
CERTIFIED BY: SAE JWL VIA DOT

Forgestar warrants that wheels manufactured by Forgestar will be free from structural failure as long as the original retail purchaser owns the product. Forgestar further warrants to the original purchaser that products manufactured by Forgestar will be free from defects in material and workmanship under normal and intended use for a period of one year from retail purchase.

Richard McDonald Evo 7 Circuit Car - Complete!

2009-11-21T10:05:00.001-08:00

CPR complete another Full Race Car conversion project for Richard McDonald.
The car started life off as a mild tuned 500hp Evo 7 GT-A Automative, but Richard requested a conversion project to allow it to compete in the UK Time Attack Club Series for 2010.

CPR stripped the entire car down to a bareshell, and then built a Full FIA Weld-In Cage Cell, along with ligtening the car and RS Differential Conversion.

Autobahn Paintworks in Blackpool fitted a Carbon Roof Skin and repaired the original Chargespeed Aero Kit and Carbontrix Front Bumper, aswell as painting the entire interior and cage in black

Tein Super Racing Suspension (previously fitted to the CPR Orange Works Evo) was fitted, along with full Polybush kit to stiffen up the suspension links.

Whiteline and Cusco ARB's completed the suspension setup for the car.

The Motor was left at the original spec, which is 2.0L Forged with CPR500HP Full Turbine Kit.

CPR changed the Intake Plenum for the CPR Spec D.I. Intake Plenum and 75mm Boomba Racing Billet Throttle Body, along with Aeromotive Fuel Rail

A major upgrade required for preparing a car for serious work is the upgrade to the conventional Oil System, due to the fact that hard cornering can cause Oil starvation. One route is to go for a Full Dry Sump Kit, but a similar prevention system can be achieved by installing an Accusump System, as Rick chose.

The Accusump system accumulates oil in a reservoir, and then in the cause of low oil pressure being sensed, the system will blast oil into the motor under high pressure, to save the bearings/turbocharger.

Rick's car previously had a lethargic automatic transmission fitted as Rick is unable to drive conventional clutch vehicle to his disability, however, Rick decided that to ensure the car was competitive, an upgrade to the transmission would be required to reduce transmission losses. CPR have converted this car from Automatic, to a Manual 5 Speed Car, and have installed the Drenth Full Race Dog Gear Set into the new 5 speed housing, along with the Ikeya Sequential Shifter conversion, as fitted to our Time Attack Evo's.

CPR then had a specialist mobility company in Liverpool called 'Da Vinci Mobility' install an automatic clutch system, whereby a trigger operates a motor which control the clutch pedal. CPR then modified the system further to bring it up to a level where Rick could use the system in a racing application, along with Flappy Paddles and Pro-Shift Solenoid Operating the Ikeya Shifter. The original Handcontrols that Rick had previously on his Evo 7 were modifed and re-installed, so that throttle and brake can be operated by hand. The interior was finished off with a Flocked Dash, Suede Sparco Steering Wheel, and AIM Digital Dash Cluster, with custom wiring from CPR to enable Rick to monitor everything on the car from the digital dash.
To meet Time Attack regulations and for safety, a full FIA Lifeline Fire Extinguishing System was installed also.

Full Group N Brake Line Kit, modified ABS System, and Twin Bore Hydraulic Handbrake were then fabricated and installed by CPR, to compliment the AP Racing brake set up.

Massive amounts of weight saving have been achieved with this project, and now with a full sequential dogbox installed, the car has been totally transformed, where Rick has planned extensive track testing to become familiar with the new setup, before competing in Time Attack next season. CPR wishes Rick all the best in his first season of UK Motorsport.

This Year

2009-11-12T06:57:00.000-08:00

We would like to round up the year by saying a MASSIVE well done and thank you to James Nichols as the owner / driver of the yellow evo VI race car, and Bob Moore as the owner of the orange evo V race car for their support and achievements through this season.
We all had highs and lows through this season of motor sport but a very happy ending for James in winning his championship with a first place finish at Snetterton.
Pushing the boundaries with huge torque and response on Bob Moore's orange twin turbo evo made for an up and down year. This offered some minor niggles with some older parts of the car producing lower leader board placements at two of the rounds with a split intercooler and an injector loom problem costing vital places. We still scored in all rounds though and good placements at remaining rounds gave a third place championship finish, showing other tuners that 'to finish first, first you must finish' :)
A very positive outcome in development that came from this 2009 season was the HUGE success of our twin turbo set-up. This offers tremendous spool capability, extremely low lag thus increasing power band width and torque and with NO compromise to BHP or high rpm performance. With very few related problems to this new set-up and with it running on three cars this season in competition and test we feel this to be a currently unbeatable concoction for road AND track use. I personally got the chance to drive this car in competition in Assen (Holland) which offered me a distinct power band advantage thus making fewer shifts and having better spool from the tight hairpin. These advantaged me by nearly FOUR SECONDS over the yellow car with similar ability drivers.
Well now its time to decide on next years antics and where to place our best efforts outside normal working time. Will we repeat this year by entering Time Attack, or is it time to move on and challenge in the LMA Euro Saloons or the new Tripple 'A' (AAA) All wheel drive championship..........Nothing is confirmed but I do smell change! :)

CPR Evo wins at USC 2009 - Santa Pod

2009-08-06T09:37:00.000-07:00

Even though CPR concentrates on building the quickest circuit Mitsubishi Evo's in Europe, we are still able to produce exceptional times in Drag, and we recently entered the Yellow CPR Evo 6 into the 2009 Ultimate Street Car Championships at Santa Pod.

The competition is open for Road-Legal Street Car's, where victory is assured by running the quickest time up the drag strip over the weekend.

Congratulations to James Nicholls, owner and racer of the CPR Yellow Evo, who won Class D - F.I. 4WD with a 9.90s @ 144.84mph , in full Circuit Trim (still fully Road Legal) on Toyo R888 Tyres.

Car Planet Racing entered a team of 10 highly modified street legal cars into the 2009 Ten of the Best TOTB VIII Competition at Elvington, Yorks 26/07/2009, consisting of some of our staff's and customers' cars, reaching victory in the 0-400m Shootout Final and a new personal best from the Orange CPR Race Car.

Team CPR

Clive Seddon - Orange Evo 5 - 950hp

James Nicholls - Yellow Evo 6 - 850hp

Max Waung - Mercedes CLS55 AMG - 600hp

Albert Yeung - Twin Turbo Evo 9 - 650hp

Andy James - Evo 5 - 460hp

Jim Moore - Evo 5 - 450hp

Rob Cowling - Evo 7 - 700hp

Mark Croft - Nissan GT-R - 580hp

Ged Jefferson - Evo 8 - 700hp

Yin Ng - S15 Silvia - 270hp

Throughout very poor wet conditions, the CPR Team performed well, with an all-round excellent effort across the 3 disciplines of Handling, Top Speed and 0-400m.

We were very proud to achieve our new Personal Best 0-400m time of 9.5s, by Clive in the Orange CPR Evo, even with a wet track.

Even more of an achievement is the success of the Yellow Evo 5, driven faultlessly all day by James Nicholls, which qualified him for the 0-400m Shoot-Out Finals.

James managed to find the extra grip on a very slippery drag track, to defeat Andy Forester in the AFP Subaru Impreza in the first heat, and then went on to win the Shootout by beating Paul Martin of the MLR in the Momentum Motorsport Evo, after a very close battle, won only in the last 60 feet.

Congratulations to James for his victory, and to all who competed well throughout difficult conditions.

CPR Car Planet Racing World First Twin Turbo'd Mitsubishi Evo 9 RS

2009-07-17T02:02:00.000-07:00

CPR - Car Planet Racing UK run the world's first successful Twin Turbo'd NON MIVEC! Evo (Karl Jackson's Evo 9 RS) up on their Dyno Dynamics 4 Wheel Rolling Road

CPR's Race Twin Turbo Kit is the World's First successful Twin Turbocharger Kit for the Mitsubishi Evo.

This Evo 9 has been built and mapped entirely by CPR, at their premises in Cheshire, UK.

This car produces 493.2HP at the wheels, around 650hp at the flywheel (using 24% Transmission Loss) and 600lbft at 3800 rpm!

All of this is achieved on 97 PUMP GAS!!!

We have no doubt that on Race Fuel, this setup will produce 750-800hp at flywheel, as this setup is currently been run extremely conservatively on Pump Gas.

WATCH THIS SPACE!!!

Full Boost of 2.0bar is achieved by 3800rpm!, making it an extremely responsive car, with virtually zero turbo-lag.

This is the most responsive setup we have built here at CPR, with response and torque delivery unlike any other conventional single turbo'd Evo. The sheer acceleration of this setup is unbeatable!

Karl Jackson runs this Evo 9 RS in the Harewood Hill Hillsprint Championships, where he is defending his 2007 and 2008 Champion Title again in 2009.

Car Planet Racing offer Mitsubishi Evo owners the CPR Race & Street Twin Turbo Kits.

CPR Circuit Evo records new personal best: 956HP/810lbft!
