Does anyone else have this problem...

Ever since I installed my supercharger I've been tapping the rev limitter.

With the torque continuing to build to redline (rev limiter) I want to take it past 6500. I just don't feel like the power is dying off ... so I want to stretch
it out some. It seems like I'm short shifting it big time and I'll have to learn how to shift it a lot sooner. power, fry tires, shift, power fry tires shift ...

I think that a set of road course stickies might help me some....It like driving on ice.

Anyone?

Maybe I'll have to install a shift light to help. I'm so busy with the power and the fact I can't feel it.... A light might help out. Don't want to over rev her.

What says you guys?

stay off the revlimiter lol... not good thats fuel cut, lean condition... i would practice driving some with the Driver mod

you shouldnt need a shift light to know when to shift, most of the time by the time its on your gonna hit the limiter anyway

It's really different from turbos / NA motors. You don't get a loss in power. The power is still building. I know all about the driver mod. I just don't want to keep my eye glued to the tach.

It doesn't help when you have other cars that rev to 8K either.

Getting used to it though... ;-)

I'm sure Rick would up the rev limiter for you if you took it in (I don't think he would charge you for something so quick). People have bent stock pushrods hitting that limiter though.

Don't know how useful this is but here you go.

My thoughts are to set the light to 6000 rpm and bump the rev limit to 6700.

I'm afraid the if I go much higher than that the motor will throw a rod or something until I strengthen the bottom end some.
I'll talk to Rick and start planning my bottom end build and heads

Thanks for the good advise guys.... I love this S/C ... ZO6's look out !!!

To be honest, I have a AUTO METER digital boost gauge. It has a setting that allows you to set a warning light that comes on when you hit a set boost level. At 6,200 RPM's, I see around 7-8#, so I set the warning light to come on at 6# and this lets me know that it is time to shift. This helps when I am going through the gears from 1st to 3rd gear. The car revs so fast that it is impossible to watch the tach or go by ear and not bounce off the rev limiter.

Leave the limiter where it is.

I hear ya...

Racervvprkllr is finally getting that tune. It will be interesting if nick locks up the stall and make a hp comparison between you two. I know hp #'s are just that but not to many smog legal s/c cars running around locally

So did that tune ever happen? Curious to see what the numbers were.

I'm still amazed at how mine pulls.

Update - I had a fluctuating idle at the time of my tune. I do not think Nick realized my battery wasn't up to snuff. I only find out a couple months ago it was running low that whole time. That battery had been installed 4-5 years before my tune. It looked new... but when I bought an Optima Battery I noticed a improvement.
My car is really smooth at idle now. I think I take it in for another tune and see if I can get more HP out of her now. I calculated my car to be 507HP and 405tq at the flywheel at this point with the old tune based on rwhp numbers from Nick.

Does anyone know what the real HP loss is for our cars with stock drivetrain?

It will be hard for me to compare because I have traclink and larger alum drive shaft. I'd like to get lighter wheels and carbon fiber drive line as my next mods. I have to wait a bit because I'm in the middle of home repairs that are way overdue.

It sounds like you need a shift light and some traction. Try getting some stickier tires and maybe some supsension parts like a tq arm, LCA's, PHB, or adjustable shocks. Also as mentioned stay off of that rev-limiter with an F/I car. Heck I bent my stock pushrods on a missed shift when I had a lid and catback. I hope you are not on your stockers still.
