R32 GTR with 303awkw at LAST

[itbmils]

Well

I have FINALLY finished running in the beast - and had it retuned after a full rebuild

She managed to get to 402hp @ the wheels - which by my math is about 303awkw – yes. Tune was done by Mazfix on their 2 wheel dyno – so does that impact on the number in any way ?

I happy with that result - based on the following 'upgrades'. I was targeting about 280awkw – using std injectors, AFMs and FMIC.

This is what I did .... (work was done by Serge @ John French – BTW)

full engine rebuild using

N1 bearings

ARIES forged pistons

ballance/linish/polish everything

R34 N1 turbos running @ 18psi (series 1s with .42 comp housing)

TOMEI adj cam gear

TOMEI head gasket (1.2mm)

TOMEI fuel pump

TOMEI timing belt

All new tensioners and pulleys

N1 water pump

N1 oil pump

minor port and polish with new steam seals and competition seats

non-turbulent dumps into full 3" system

std injectors cleaned and flowed

APEXI PCF with EBC

SX fuel reg

congratulations. now go show everyone who is the boss

must feel good being able to blaze rubber whenever you feel

Not sure what the losses are for a GTR but if it made 400hp on a 2wd dyno then obviously you dont have ~300awkw, you have 300kw at the rear wheels. Which is pretty well on the limit for standard injectors as in theory they should max at about 520-530bhp.

Sounds closer to 280awkw's.

I would deffiently be upgrading the injectors,

Nice graph though, are you going to be running it down the strip, 1/4?

Easily a 12sec car... maby even a high 11 with nitto's...

Nice power you l are certainly pushing the limit of the injectors and afm's . Should do an 11 if you can have your 60ft times around the 1.7 mark . I've got about 300-320rwkw ( 300kw before we changed the restrictive exhuast) out at wsid the other night I did 11.6@119mph with a 1.7 60 ft tyres were nothing fancy just bridgestone potenza's.

Is your ECU taking a few degrees out at the top end?

That power curve looks really nice but looks like its either maxing out you afms or taking out timing due to leaning out /pinging

thats pushing the o'l injectors pretty hard!

If you got a rebuild done i would prob spend the little extra and get some afms and injectors to complete the package.

sorry if i sound like a pesamistic dic*head.

looks like a really nice power curve, but i have seen too many cars pushed on standard injectors and go BOOM!!!

great result tho

[Boosting]

Dont want to burst your bub ble but dont standard engines reach that power anyway, i have a set of 32n1's and are maxing out my injectors to, (400hp)and when the ca was standard ran a 12.1 at 114mph at 247rkw

I think u need bigger injectors and airflows with a proper tune, no offense to archie at mazfix but ive seen some of his tunes, and do not like the result when compared to other people tunes and end results.. Im thinking your car should be able to do alot more i would be looking at the 500hp at the rear wheels with that, should be achieved with more boost and better tune.

hey i got a bit more mods than yours but.

what clutch are u running?

i am still yet to dyno tune my car yet

[itbmils]

OK OK

FYI - I have a pair of RB25 AFM in the boot already - just waiting for a suction kit before I can fit them up. I'll also be upgrading the injectors (550cc HKS or SARD I think). I'll then take it for another dyno tune and push for some more.

I KNOW some of you also get these types of numbers with std internals, but for how long. I was running R32 N1s before my rebuild - without the PFC and using std internals - and it went BOOM. At that stage I was getting ~210awkw.

I'm still happy with ~300awkw with this setup – and I know it will drive hard all day.
