400 whp on N/A VQ possible?

12nismo · 01-29-2015, 01:59 PM

Its 5th...thats as close to 1:1 as I can get...still a little under which is why my tuner said that my numbers would be slightly lower than what I would put down with stock gearing.

Yes, 1st gear is pretty much useless, lol

Don't be mad, not trying to start anything...but 330ish, maybe 340 on a good day. I think Z1 did show after begging 340 on E on SAE with everything included full port jobs on TB's and mani's. Question I have now though is how did their DJ show 340 when mines showing 312 minus E. I mean I'll take 28hp for E!!!

"This is also important for comparing results at the same dyno shop, for example, here in Las Vegas our atmospheric pressure stays relatively consistent, but our temps vary from 38 degrees to 118 degrees. So the same car with no changes will certainly make less power on the hot day compared to the cool day, but applying the SAE CF allows us to make an “apples to apples” comparison. If you take anything away from the last few sentences, it would be to ask your dyno operator to make sure that he is showing you SAE corrected HP figures, and before I get off my soap box, I will say that there are certain Dynojet dyno owners who apply the “STD” correction factor, and that’s not proper to do. The STD CF is an older standard that yields slightly higher HP numbers, so don’t allow yourself to fall into the trap (just use the SAE CF!!)."

I believe STD is what Z1 uses.

When you say under, you mean like 0.90 instead of OEM at 1.00?

Also if the 6m is 1.20 in 4th, and the auto is 1.40 in 4th, cause the 6m 1.20 is closer to 1.00, the 6m should put down more power if the drive train loss is 100% equal (which I'm sure it's not).

Yea, I'm closer to stock 4th gear gearing with the 4.08's in 5th gear compared to a stock 3.6 geared car in 5th gear...if that makes sense.

I wanna race haha! You said aluminium flywheel right? What's the weight?

Plus E, plus 4.08. PLEASE do SAE one day, I wanna see the difference vs me!

Whats E? E85?

synolimit · 01-29-2015, 02:25 PM

Yeah

12nismo · 01-29-2015, 02:26 PM

The 345whp is without E85, i'm planning to do E85 next...hopefully that will put me over my 350whp goal.

Right I know. I'm saying when you go back to do E please click the mouse and just print a SAE, takes 2 seconds. Since my next visit will be E also we can compare. I just wanna see on equal fields what a light flywheel and gears do.

What's the weight of yours?

Definitely. i'll let you know once I swap over to E. Maybe I should look into doing your ported lower mani and T.B.'s

I've never weighed it, but stock nismo weight is 3,314lbs. With the headers, exhaust, seats and spare removal, I've pulled around 200lbs out of it. My guess would be that it weighs somewhere around 3,100lbs.

Maybe. Sub $1000 for 10hp I bet just like sub $1000 for 10hp for E85.

No weight of the flywheel. Trying to figure out what you gain from that as you have less drivetrain loss I'm sure.

My bad, the flywheel is the 14.5lb Southbend aluminum flywheel.

speaking of clutches and flywheels. Do either of you two fella have an upgraded master cylinder?
