Got Over 400kw Atw?

[N1GTR]

Go back about 2 days worth in this thread. Name to look for is FINELINE

[dato$2nv]

yeh they are laggy but this is bush bearing turbos on low compression rb26 with seals that are on the way out lol!!

can only compare the gearbox to standard so dunno , feels closer ratio between 2-3 3-4 , and im not stressing to break gearbox when i drop it at 8300 limiter , every other drivelien part is another story lol!

when the turbos finally let go will probs chuck on some -5 for comparrison but dunno how well they will with this low compression!!

[Piggaz]

How did the low compression ratio come about?

do you mind if i ask how much your rb25/30 set up cost??

1.5mm head gasket makes a massive difference

[N1GTR]

Any reason you went so low? For your boost level it would've been fine on standard 8.5:1

Good to hear about the gearbox, everyone that's driven one reckons they're hot shit and well worth the coin

[N1GTR]

I had to guess a couple of numbers but came to 7.9:1

Not that it matters cause you're clearly enjoying it an that's what matters!

[Rolls]

Can always change it, head gasket isn't as bad as changing pistons lol.

Agreed.

Just change the 1.5mm one out for a standard gasket, weld the wastegate shut, turn the fuel pressure up, set the injectors to 100% and hold it flat.....good times

[HYPED6]

Umm, I think its safer and correct practice to max your injectors and keep winding the boost until your mixtures are correct.

That's how I understand it any way?

Oh there's one 400 club member who's a happy camper tonight. As far as spreadable power, it's pretty much WINNING!!!

Will overlay the graph with another big engine to compare, just got the graph straight from the dyno so it will have to wait until tomorrow and ill go to the dyno and take a pic thats worth posting in here rather than the one i have currently which was just a quick one

[Marko R1]

The suspense is killing me stevo...who owns the car? Who tuned it? What turbo setup is it running?

[Marko R1]

Hang on, it must be a yavus tune right

[NYTSKY]

It better had been 30psi+ or GTFO!

Its all day after tomorrow like now, I figure you should at least share some details after this much waiting

[r33_racer]

Come on....get the results up!

[N1GTR]

OK guys here we go. Didn't get to overlay it which was a shame, but did get a much better pic.

This is Paul/Piggaz's GTR of course. Turns the wheels in 2nd gear on 265 semi slicks. The thing to note is that between gear changes, unlike so many other cars out there, when you have selected the next gear and engaged the clutch - this thing is already making ~400rwkw instead of being off boost or out of the meaty powerband. It's got a great spread of power, and it's fast! There's another 30-35rwkw in it top end with cam timing but it's setup for overall power not a peaky figure. So much fun, he could charge admission for a ride in it.

Not to take anything away from Paul, but RB30 still rules
