[No Crust Racing]

A solid 600+rwhp with solid response will be such a drag mate =\

Area under the curve is more important than top end power IMO, your car will be mental. That's why i designed my car the way i did. 

Even at my relative power level i find for street work, it's getting to the point the extra power is useless. 

I'm loving my current tune on 98, i can't wait to see it on E85 again.

I believe Scott is spending all day on it today. No idea where it's all upto apart from the information I've posted.

Cant see it making anymore than 480 awkw. That's as much as Scott has seen out of a 8374.

how hard are you planning on pushing it - boost wise?

Whatever 125,000 Rpm is. It will be higher early on then taper off as the engine consumes more air. 

So. Bring on 125 k ASAP and leave it there. Boost, who cares but at guesstimate, 30 ish psi as it comes on (late 3000's/4000 ish) and mid 20's at 8000 rpm. With any luck, hopefully less "boost".

interesting. looking forward to it.

Just for fun rather than anything else - i compared my power in the midrange compared to yours - i'm at ~100kw at 3700 - you've got ~270kw - same turbo lol

I need me a stroker kit

Has the fluff fallen out of Ernie yet? Otherwise not a real EFR

Lol. When are you going to man up and buy one. Piss off that nug PTE ?

[Piggaz]

Update time!!!!

Fuel is E56 only

Still not bringing it on as hard as possible, just letting it come up as normal (not tuning via turbine speed YET). 

Turbo is a EFR 8374/1.05 AR turbine housing.

300 KW at 4000 ish, 461.5 KW at 6000 RPM then it falls over. I didn't see this coming but the issue is the turbine housing is too small! The next size up is a 1.45 AR which is the same housings they used on the indy cars. They were saying that the head is  just breathing like a weapon. Funnily enough, both Petes and Intune's car were able to stretch to 8000 RPM even though their engines are larger!

For the time being I will take it back and enjoy it for a while. If I put the 1.45 on, Scott thinks it will see 500 KW and make even more through the middle by 20-30 KW. However, i'll lose a tad at 3000 ish RPM.

I suppose I better get used to short shifting. Lucky I have 6 gears. 

For those of you who are hooked up on boost numbers, 25 psi at 3850 ish RPM but that will improve again. Pretty sporty for a lazy, laggy single turbo

That's just rediculous lol

I can't wait for you to drive it and report back

Start a Kickstarter for a 1.45

Go put a 6258 on your car.

I built mine so I could have a strong top end . I want to keep it and as tried to get it as good as I could down low . 

I don't want to loose anything from the top end, I still can rev it to 8000 if I want .  Just like it a bit different than most I guess  

That head you had done is something else , cannot wait to see it all working together, what a machine 

I just found a pic of you

Congrats Paul, now enjoy it for awhile and mull on can of worms thats just been opened but was hiding there in front of you.

What brake set up are you running ? Reason I ask you may find that other things may need upgrade first, like stopping ,fine tune the nadling (think you sorted that but f**k me too much alcohol brain damage cant remember shit) then sort last power upgrade, all just subtle stuff. Then you'll have the ultimate skyline weapon.

 

[No Crust Racing]

Ultimate? 

It has 4 gears too many bro!

Brakes are sorted, mate. 365 mm 6 pot fronts/350 mm 4 pot rear alcons. Need to change the front pads, the ones in there are woody nuggets!

Suspension and arms are all sorted, although it needs a wheel alignment. The whole rear end has been out to replace the sub frame bushes.

Cant believe I'm out of rear housing. Quite strange that the 3.2 and 3.0 can go to 8000 rpm but the little 2.8 cant. I suppose those polished ports ain't so bad after all ;).

I have in my head the 1.45 isn't a straight bolt on. The housing absolutely MASSIVE!!!! Adrian (bloke from Insight) said if they made a 1.6 you'd put it on haha.

Data is showing 46 Psi in the exhaust manifold. 

Im heading out tomorrow to sit down with Scott. Grab as much data as I can.

[acsplit]

So tell us the truth, you actually did a 3.4 upgrade while "it was waiting for a tune"

[Piggaz]

. Nope, engine remained untouched. Cams weren't even touched between the -5's and 8374.
