getting tuned 7/27/10

Diocletian

Damnit, that's 18HP more then me, are the combination of LTH, u/d pulley and gears helping that much?

Also, I thought switching to the 4.08 gears broke the SRM(as well as cruise control but who cares) on 7ATs. If that's seriously not the case I think I know my next mod!

Edit: J, I need to visit you at some point, I need some paint touched up on my car and I heard you have a body shop near you that does excellent work(I saw RCZ's car).

we did a bease line @ 308, then went from there. as for 8k i dont think nissan build this engine on the ragged edge to where a 500rpm increase would be detrimental.


no prob just let me know when you want to drop off the car

I think Nissan is pretty intelligent when it comes to engineering an engine and giving purposefully giving it a redline of 7500 rpms... so pushing it back to 8k isn't going to hurt the longevity of the engine by a "detrimental" amount?

I was thinking about this this morning. Manufacturers of production cars always err on the side of caution, so I figure the car should be able to rev to up to 8,000 RPM with a proper tune N/A without issue.

That is very true, thanks for the insight. I figured I would ask anyway since the VQ serie engines are very stout and well engineered but each brand and type of engine is slightly different.

8,000 rpm sounds awesome on the dyno run!

That's a good point, 8,000 does sound extreme given the fact that the power of these engines still peak very high in the rev range.

However, if someone could confirm that pushing the engine to 8k rpm would barely affect the longevity of the engine it'd allow for more time at the peak power level...which would make the use of full exhaust, cai, u/d pullies, 4.08 gears, and tires modded cars even more potent. Definitely something I may be considering (minus gears).

Would be curious to see how fast a 1/4 mile pass it could pull off.
