Breaking...:eek:

Normally guys hear the motor go flat when they start to float. Other guys don't notice until the valve hits the piston.

Oh my bad. It must have been 4th gear. I won't go over the speed limit for th tires, so that makes sense. But ya, the fastest I got in the NA VE was 130. In 4th not 5th. It's been a few years.

I...

All motor I got to about 130mph when I hit the rev limiter in 5th @ 8K rpms. Stock VE with sr16 tranny.

With the P11 tranny and turbo I got to 175mph on level ground, verified by the gsxr1000 d...

he is probably suggesting b13 or p10. The OBD2 cars have a crank sensor, and most fidanza flywheels trigger a CEL. If you don't have a crank sensor, then get the fidanza.

This may be true, but I have bounced mine daily for 12K miles without issue so far. Granted I may not get to my goal of 100K miles on this build, but meh. I want a safe limit to prevent float.

I am so lost as to where I will be most happy. I want to rev high, but don't have a standalone. Decisions...

Maybe just the stock 20ve cams and 8500rpm with an msd rev limiter would get the most...

So with the stock sr16 springs and sr16ve cams the max safe rev limit is around 8500rpm? or 9K?

And by safe, I mean bouncing the rev limiter constantly, safe.

Has anyone seen or experienced this in person? I have a few guys here who have dynod at sea level and up here, and their corrected numbers are really really close.

Here is a dyno chart from up ...

9k rev limit would be sick. But really I just want to have a broader powerband and that can only be had buy building boost really quick, and holding power as long as possible.

Mazworx, BC and franklin all make S/R combos. But I think the Maz stuff is BC?

DE stuff can't be used with VE.

I don't think he meant the N1 cams, I think he meant the plain sr16 cams up to 9k.

The n1 cams would be insane! But I don't think the power would come on soon enough. Perhaps the 20V/N1 grind wo...

Since I am at high altitude I am looking for about 460-480whp max before this turbo can't keep up. Guys are getting about 550whp at sea level. I have been the "big boost" route and now I would like...

Oh I got ya. I will stick with the 20ve cams if I get valve springs, or the sr16 cams if I stay without.

??? Lower lift profile? 11mm intake and 11.3 exhaust. Nearly same lift as the sr16 @ 11mm on both.

Except I only have a 248* duration, instead of 280*.

I have an sr16VE head, so I am not sure which springs I have in there now. But I can tell you the ramp angles on the VET cams is way more aggressive than the standard VE cams. I run to 7500rpm now ...

Safe max rev on SRXXVE cams

I am changing to a tubular manifold next month. So I will likely go with the sr16 cams if the standard 20ve cams don't give me the power I want. I really want to make the most power I can without u...

Thanks for taking the time to read it Ben. The only thing is the math, and it is something that can be a little confusing.
12.5 is only 85% of 14.7, (this is where you get 15%)
but 14.7 compared...

It depends on the ve. 20VE is 10.3, 16VE and 20V are 11:1. I would imagine you need at least 87 octane, and that depends on where you live. Higher elevation will need less octane.

Try this... Put your finger over the breather hole and give it a sec. You can feel the vacuum after just a sec. It isn't really strong, but the vacuum is enough to pull extra unmetered air into the...

Glad I could help out ;)

Another thing to consider about blowby is the lifespan of your oil. Blowby degrades oil faster by thinning it out. A bit of fuel vapor is part of the blowby. There are t...

OOH I am aching for some good turbo grind cams!

It goes pretty deep, but the big challenge to getting accurate results is getting an accurate VE guess. VE changes things big time.

Keep in mind the hp estimate doesn't take into consideration ...

THANK YOU TEKKIE!!! I will edit my original post with your link.

Thank you so much!

If you could, just register at UN and then download it. It will take me a while to DL aim, this isnt my computer and it doesn't have it.
