Project P1 600bhp +
 

Hi Everyone.

I guess some may be interested in my current project, so I will keep this thread updated for those interested.

Purchased my car nearly 3 yrs ago. An original P1 that had been looked after and had modifications as picture below.

HKS Induction - PACE f/m Inter cooler - Ali Radiator and was running at around
310 bhp.

The car ran well with good handling due to newly fitted original Prodrive springs & dampers.

After a year I wanted more power and after spending much time looking into the various companies I decided to go to Roger Clark Motorsport.
Matt Clark designed and built the engine which took several months to complete but it was worth the wait.

The Inter Cooler is an APS series R 725 (9075cm3). The P1 in the picture below is not my car however the Intercooler in the same model. The car in the picture, RCM's Impreza "The Gobstopper" and my car basically have the same block and internals but are running at different specs.

My engine is 800bhp + compatible however it's currently restricted to 420 - 430 bhp by the turbo.
We need to make the car stronger so it will cope with 600bhp + when the twisted turbo is fitted in early 2009.

My existing provdrive brakes have been sold and just had all new AP Racing brakes fitted at RCM.
Fronts are 6 pot AP Racing on 355mm discs and rears are 4 pot on 320mm's

Next up is new suspension being fitted in November.
They are EXE TC with 40 adjustments available to all corners. Olly Clark was telling me that around 25ish for road and 30 - 35 for track days, hill climbs extra. Will be subject to conditions and locations.

Dec / Jan will see a new 6 speed box with RCM internals?, Carbon prop, drive shafts and possible diff changes.

Attachment 50181

The engine management (Motec 800M) was mapped by Dave Rowe of Motec.

Anti Lag is enabled and Launch Control will be enabled when running at 600+.

The new suspension should prove good as I lose traction on damp roads in 4th gear at the moment. It is my everyday car and although it's very quick it can be driven normally without any problem.

When complete we are expecting the following performance stats:-

0 - 60mph & back to zero in under 6.0 seconds
0 - 100mph in 7: something?

Here are a couple of odd pictures with the last picture being the most recent.

Will keep this post updated. :thumb:

Fantastic, amazing spec. :thumb:

Wow!

Have you won the lottery?

Looks Like a Similar Spec to Marty's P1 also done by RCM.

I'm currently building a 600bhp V3 Type R with RCM parts.
Mine is based on a 2.0L closed deck block that's been linered to become a 2.5 Closed deck block. I'm using RCMS WRC Rods, Omega Pistons and already have their rotated Turbo kit. Quality of their stuff is fantastic.

Good luck with it :)

Hi Triple.

Yes it is much the same as Marti's. His car is lovely.
Your correct, RCM's parts, quality and general service is the best.
Good luck with yours matey.
Hopefully we may meet up one day somewhere ?

Fudge

How to empty your wallet of lots and lots and lots of cash :D

Which version garret will you be fitting ???

my god, what a spec. cant wait to see her finished. as above, what turbo you going for?

thats one impresive spec and would be one intresting car once its finished,good luck pal

wow!!!
not jealous much.......... ;)

very impressive spec.....but why do you want 600bhp in a everyday P1
:wonder:, I have trouble with 460bhp in my P1 :)

Cause 460bhp isn't enough, well not for me anyways ;)

Not sure at the moment but it could be the Garret GT30/37 turbo with .82 exhaust housing

thought you were going for 600?

Well....the engine will cope with it so why not. I have always wanted to keep the appearance of a P1 without modifying or removing sections off the front.
Matt done a great job fitting the APS Inter cooler. I only lost the two driving lights hence the light covers.

I have not seen you in the P1 forum before mate??.
It was good to hear that you were running at 460. Couple of questions:-
Do you lose traction at all in the dry? what is your general mechanical grip like?
and is yours RCM?

Cheers Bighead

Your going to need a gt35r as a minimum to come close to 600bhp

sorry Garret GT 35-40 turbo

Love it! :notworthy Another RCM masterpiece! :thumb:

Is that the twin scroll? version of garret ???

Thats the suff if the engine will take it then why not. Hats off to you great car keep us posted as it is nice to see that not all really fast subaru's are a firm's car.

what sort of price we looking at for this spec. pm if you would like to share
best of luck with car

jim

I think between the £20-30k mark ;)

Nearer £30K.

You got your car back yet Steve? Just worried about my lift on the 19th :norty:

Ahhhh , nah its still off the road. It might not be back in time :( As long as mine beats shauns ;)

Very nice spec.

Do RCM do all the machining work for the engines in-house?

What a beast, nice one skullfudge. I know how much i've just spent on mine to hit 400bhp, excellent work mate.

Skullfudge,
Awesome piece of machinery! :)

Steve,
roflol

If yours didnt beat a piddly GT30 standard position turbo, I would drive yours in to a brick wall. ;) Thats like saying as long as my 911 turbo beats a boxter. :D Stick a GT35 on mine and then see what it does, as that would be a totally different story. Litcho's hybrid GT35 Type25 Race Car acheived 585bhp on pump fuel using my engine spec. ;) I await to see what my new GT30 does next week, when it is fitted. :D

I'm look forward to seeing what yours does Shaun. Would be good bench mark for mine. I've posted on 22b hopefully you'll make it :)

I sometime go on the P1 forum(read very few and far between as I am on here most of the time )
with 460bhp....my P1 will loose fraction in 1st, 2nd and third on my uk 6speeder gearbox with rcm carbon propshaft , my spec is very similar to yours (except i have supertech valvetrains and a MD321T turbo on a sti 2.5 with rcm forge internals )

I have whitline anti-roll bars (fr and rear) with alloy droplinks both ends
also fitted whitelines anti lift kit on standard P1 suspenion
I will say imho that 460+ bhp is wasted on a road going P1 ...as will not be able to use its to it max on the road as you can go just as quick with 400 as with 500+ on the road :)
on track is a different story !!

I am actually going down 2.35 route as I type this (for a stronger engine )

I know Marty's just about to have his engine mapped for race fuel, 125 OCTANE:thumb: These cars running over 500bhp must be scary on the road, that's going to be my next stage of mods:norty:

Shaun :)

MIne is only the baby gt35r as mine is only the .63housing so say 550bhp max
