Results Of My Gtr Tune

[Mik]

Rolled my car onto Bel Garage's dyno yesterday. I have attached torque and power curves.

The most we saw was about 990nm and 390rwkw, but my injectors were more than maxed at that level, so we took out a bit of boost.

awesome result, what setup u running? turbo/s, etc?

how come from 5100rpm its not making anymore power? (not having a dig, just a question)

I wish it made all of it's power by 5100RPM! The aim was not to make peak power anyway, but to get the most area under the curve.

I'm still running the useless laggy peaky GTRS turbos, but somehow, they don't seem so laggy now.

Oh...and the dip towards the top of the rev range is wheelspin on the rollers.

awesome result mate. 370+ kw at only 5100rpm is amazing

can i ask what type of cams you are running now? and injectors afms?

it must really hammer from about 4500 onwards.

[SLY33]

nice! at what boost is it? 1.4? 1.5? these things are supposedly good for nearly 2bar. excellent for a stock stroke 26, would be pulling nice and hard by 4500. once you do your injectors, ive seen these hold power right up to 8grand!

what cams are you running?

beat me to it beer baron

Increase the revs if you can

Stock bro, even has a stock airbox .....

[m&m]

Fantastic result.

[lwells]

Gah. Ignore me, I am tired and can't read

Very impressive result. How is traction on the road?

[Blitz]

Nice results there Mik - Get some larger injectors in there STAT!

Why would traction be an issue? It's only got 370rwkw... :lol: Seriously though...traction is not too bad, but I do have pretty sticky 275s all round and it does like to randomly break traction in 2nd when it comes on boost.

Nick...to be honest, I though 700s would be okay. They are about as big as I would like to go on a daily driven car. I'm also running a bit more rail pressure than I would like.

Also something to note is that the torque figures estimated by these dynologs are apparently pretty accurate....just ask Morgs and WilliamsF1.

[Abo Bob]

Nice Mik. I should have stayed longer...

What fuel pressure did you end up with at idle?

That's a 3 inch exhaust and stock airbox too guys. Shows what's possible.

[Beer Baron]

yes, but what cams and afms?

yeah there is nothing wrong with stock air boxes really. if my car had come with one i probably would have used it.

[Ginkgo Biloba]

thats great, but why not go to a 3.5 before you do the tuning? surely a 3inch is restricting a bit of top end?

is wrxhoon correct in saying the cams are stock?!

[Morgs]

Awesome Mik, I'd definately upsize those injectors and pump a bit of boost into it. The new motor sounds like its a good one.

Edit: Mine only made 350kw at BEL which on CRD was 319Kw at all four, as a reference. Has since changed.

Is that the same dyno Jerry made 240rwkw on with his car?

Nice result - doing anything else to it or are you finished? Whens it go to the drag strip?

[Mik]

I don't really care about the numbers to tell you the truth (although the torque one is interesting).

So your car only made 319 at CRD? That's so odd...after what you made at SMW, and speaking to Jason, I would have expected heaps more than that.

Also, Tommy's car made 330ish at CRD irc and a bit under 300 on Bel's dyno in the same state of tune.

I'm more worried about the shape of the curve and how it drives, which is why we spend a couple of hours on the freeway cleaning up the spool-up.

I'll go to the drags eventually, it will be a while though because I'm flat out with work atm.

[Beer Baron]

yes, but what cams and afms?

<{POST_SNAPBACK}>

yes the curve does look very good. and like you said the dyno graph is really only relevant to you. It's just lets you know how much improvment you have been making.

[Ginkgo Biloba]

would love to confirm the cams, and what boost!!?

<{POST_SNAPBACK}>

No Andrew , i expect my car to make about 260-270 rwkw on that dyno, but my car is pretty gutless , just about everyone makes more power than me !

I will let you know what power mine makes on this dyno when she goes on it soon .

(yes, but what cams and afms?)

Beer Baron : refer to post 7 . There is plenty wrong with airboxes when you make that kind of power, but he wants a stock car .
