-7 Turbo's And E85

[800KD]

My old 33 gtr had Garrett -7's, on 98 pulp it made 325 awkw on 20 psi and ran 11.9 @ 118 mph

[GTR_JOEY]

I agree with Ash,

i really dont see how by just adding E85, you can take a great -7 result like 325awkw ^^ on pump and make it go 370 plus on other cars

at the end of the day, if you have the MPH we really cant argue

[gtr jet]

I never thought I'd get anywhere near 370 with -7s but I was wondering if 350 was too much to ask for.

I'm not too sure what GT-R's are like with power to mph as I've just come from an XR6 Turbo that ran 118 mph with 297rwkw. If I could get around that sort of mph I'd be pretty happy.

350 would be the norm result and somewhere around 120-123mph should be a good goal. Cams will stretch you out further. im a strict 98 no cams believer but add E85 into the equation and MILD cams are a viable addition.

[gtr jet]

Well that was what I was hoping to here. 350 and 120mph would be about my goal. Not willing to change cams. I've spent enough money for the moment.

Also what times would i be looking at with 120mph? High 11s?

[Piggaz]

Mid to high depending on your 60 foot time.

[gtr jet]

Beautiful. Cheers for all the help fella's. I'll keep you posted when I find out my results.

[800KD]

Mine did an 11.9 with a 1.7 60 ft and 6000 rpm launch.

Good luck and have some fun with it!

350rwkw in a R32 GTR would see you closer to 124/125mph, this would be low 11s easily.

In my 33 GTR which is heavier, i ran 123mph with 340rwkw and 11.3

[gtr jet]

I'd be over the moon to run that time and mph but i'm a bit more realistic and would be happy with a high 11.

Any idea whether a 3" exhaust would be holding me back at this stage and whether upgrading to a 3.5" would be of much benefit?

3inch minimum. 3.5 better.

[gtr jet]

I guess i'll stick with what I've got now and when I get bored of the power i'll go 3.5" exhaust, bigger injectors and fuel pump.

[(OO)SKYLINE(OO)]

300 rwkW = 3"

350 rwkW = 3.5"

R31Nismoid's rule of thumb

[gtr jet]

I thought that's be the case. I'll have to look at my whole exhaust though as it's nothing flash. HKS dumps with some generic Japanese front pipe and 3" cat back. 3" Ballistic cat.

[(OO)SKYLINE(OO)]

You should be fine.

Until you want over 350 rwKw, assess it then.

[gtr jet]

350 is plenty for me. It'll mainly be a track car anyway.

[SiR_RB]

Do said mods

Run it at track and post ur time/mph

[gtr jet]

Will do.

[DVS JEZ]

Check the size of ur front pipes. Theres alot getting around that are tiny 2.5 inc or so. Upgrade if required

[gtr jet]

Do you mean 2.5" where it joins to the cat? If so mines 3". It's a little squashed at the front from bottoming out though so i'll replace it eventually.
