R33 Gtr Dyno Result,cams,afm,pump

[m&m]

Ice Performance just finished dyno tuning my GTR tonight and I am very happy with the result.They actually hit a peak of 365rwkw,but toned it down to a safer 351.9 rwkw.

The car has

HKS 2530's

HKS dumps

HKS 264/264 cams

Z32 afm

Tomei pump

Nismo 600cc inj

Power FC

HKS ebc

HKS super dragger exhaust

Trust cooler

Arias forged pistons

This was done using Boost98 E10 fuel,if Extreme100 was available in more servos I would have used that.

Congrats mate, bet it hammers now Very nice powerband..

Any idea when you'll be heading out to get some numbers?

[sav man]

very nice power.

what lift do the cams have?

sweet! throw it in the 26 results thread!

[m&m]

From memory the lift is 8.7mm

Just took pics of the engine bay.

thats a very handy looking gtr you got there.

350kw is awesome well done

love the useability of the power band. should be quick on the road

Nice result. Was talking to G about it before.

Love the rocker cover pics... G has been raving about the colour that Nick did em... it sure does look farking brilliant!

[The Mafia]

I think I am in love...lol

Whats the go with that strut holding th motor? Stop flex?

[RANDY]

Engine brace.

Gerald has claimed the color,its called "ICE G GREY" :lol:

good stuff. Can i ask at what rpm it hits 20 psi? Looks to be pretty streetable.

[m&m]

In 4th gear its making

5 psi @ 3000rpm

10 psi @ 3800rpm

15 psi @ 4100rpm

20 psi @ 4500rpm

22 psi @ 4700rpm

It makes over 300rwkw from 4800rpm,still making 350rwkw + at 7500rpm,extremely flexible on the steet.

The only other mod I want to make is to fit HKS exhaust manifolds,expensive labour wise for a small overall gain,but response should be even better.

[Beer Baron]

awesome. sounds very good.

[pnblight]

M&M nice work and nice result for such low lift cams. I can personally say the HKS manifolds are the shit (awesome construction quality) and can i ask did you play with cam timing and if so what did you find to work the best.

ps nice engine bay

I dont have an adjustable cam gear on the inlet side,only the exhaust.I was going to ask on here what sort of results people have got with this setup, which should be fairly common,with cam timing adjustments.We have left it alone at the moment,maybe in the future.

well i would most definitely put an adjustable cam gear for the inlet on the wish list and you can really adjust the sort of power you get and quiet offen (most chaces increase out right hp) with adjustment of the cam gears. the inlet tends to adjust how early the power will be made ie a little advance can quiet offen bring the whole power curve on earlier and the exhaust advance can offen give a bit better top end hp. I stress every motor is different but i have not seen a setup (rb26) not responce to cam timing in some fashion its offen only other factures that limit the gains that can be had for cam timing ie the turbos reached peak efficience etc

I really thought most of the benefits with adj cam gears was with stock cams.I would have guessed that HKS cams would work best straight up,or that gains would be minimal.Anyone have dyno figures of gains or do I have to be the guinea pig?

dude your no guinea pig i have worked the cams on like 6 different rb26 all have responded to timing some a little some a lot. The first of which was my own awhile back

the least gained was still around 30rwhp with less than half the timing i had to put in mine. Each motor is different and dont always think that a little cam timing is different you may just be adjusting the cams to the correct relationship to crank as manufacturing tolerances can cause differences in this (we are talking small) but considering that 2 deg of crank timing (=1 deg of cam timing) gave me 30rwhp a small difference can be of great benefit Yes?
