[COTW 5/9/11:] STS Turbo Installed - Page 40 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Ok, I get the 1-2 shift thing. It makes sense to me, and about the losing boost between shifts in a manual car....

...but in the first video posted above the ABM got off to what looks to me like a nice launch, but yet the VR Camaro seems to catch him towards the end. Even with the loss of boost during shifts, how in the world did that NA V6 catch the boosted V6?

Could the loss of boost and then trying to spin up the turbos again cause that much power loss while trying to spin em up again?

Sorry, just seems strange.

You'd be able to launch at a little high RPMs, building more boost off the line. Are you looking at a shift light? When it bounces off the rev limiter it feels like forever until the computer gives control back. I'm at the point where I have to shift to fourth right as I get to the first set of timing lights or bounce off the rev limiter.

Yeah, Rich was telling how long it was taking to recover from hitting the rev limiter...

Ahhh...OK! Looks nice! I wasn't sure whos that was so I just decided to refer to them as 'ABM' and 'VR'. My bad.

Rdditten · 11-07-2010, 08:01 PM

Your right, even spinning the tires, 1st and 2nd I jumped out ahead about a car length each gear, then something went amiss. Take notice of the exhaust. I had hit the limiter and it wouldn't recover. I will be working on it. I feel as I have said the potential is there, I just have to get it all to come together.

Oh, you have a nice color on your car! LOL

Rich appears to get a great jump on me because he red lighted. Keep in mind if he bounces off the rev limiter on his 1 -2 shift and then again on the 2 -3 shift the race is over at that point. Our Camaro's are going thru the traps in 3rd gear. No time to spool up again.

Thanks Scrming. Correct it is IOM, even thou we know

it sometimes appears to be VR.

Rich was even thinking about short shifting, if I remember correctly to help it from bouncing off the rev limiter. Rich was thinking the rev limiter was at 6800 and I was thinking it was 7000 RPM's.

Rdditten · 11-07-2010, 08:15 PM

Oh, yeah, I did have a -.143 light on that one. I forgot......

NP. I was just pointing out why it looked like a big jump. My reaction time wasn't exactly the best. Still working on that. My 14 run avg. was .308 with one red light and two of them over .5 (guess I was taking a nap).

How fast a car comes up on boost has everything to do with the size of the turbocharger wheels. The power a turbocharger, and by design, the engine makes is dependent on the size of turbocharger.

Bigger turbochargers make more power.

Smaller turbochargers make less power.

The smaller turbo will come up faster than a bigger turbo. The more displacement and exhaust energy you have, the quicker the turbo will come up.

Pick a turbocharger by the power you want to make. Build everything else around that. If you want to make 400 hp, the turbocharger will be much smaller than a turbocharger that will support 1000 hp.

agreed. there are benefits to both..a smaller turbo would mean a quicker power band and more fun to drive. bigger turbos mean slower power bands but big power.

I believe it is 7K.
Any v6's with a shift light?

Is not possible to vary?! My dyno runs drop off at 6800 and 7000 and i dont think he lifted?? If he lifted its 7k

just trying to help..

SIXJAK · 11-07-2010, 11:58 PM

Does anybody think the STS setup would pull 13's on a 6AT? For reference, I ran a 14.7 in the summer which corrected to a 14.006 in a stock 6MT with the RS 20's and running 87 fuel. I have raced and beat all the other autos (SS included) in our small fleet.

Don't feel too bad. My bro with the SS auto cannot break into the 13's. He's messed with his Predator ad nauseum, has tried mixing 110 leaded with 104 unleaded and no dice.

Keep at it. We are all still very interested. Thank you for posting your results. I'm a little less frustrated with Hennessey and Lingenfelter now...lol.

There are no shift lights that I know of and yes that 1-2 crunch does not sound nice. But I ran my best time "crunching".

Oh, I believe they can have some variance. I just know at around 7k mine feels like I've lost control of the pedal.
