How far do you take up the RPM's when you shift at WOT?

Bolt-ons and tune I had the shift-lite set to 5900. Now, with heads and cam, I have it set to 6700.

Shift where youre car makes peak power at.

I think i shift right around 6200-6300rpm. I see no need to take it any higher then that.

No, you always want to shift higher than peak. The stock cam flatlines by 5500, but you don't shift it that early. I have experimented alot with shift points with my setup. It peaks at 6400, and having the shift-lite illuminate at 6700 has netted me the best results. Shift RIGHT at peak, and you are guaranteed to have shittier times/traps/results

Before changing my clutch. my peak power came at 6300 and I would shift at 6500-6700. I need to put the car back on the dyno. My cam should make power all the way up to 7k.

It all depends on your particular setup. There is no real way to blanket the shift point. Just becasue one way works better for you does not mean it will for me.

BriancWS6

True, but only to a point. While one setup might like you shifting it 300 higher than peak, another might like it to be shifted 600 higher. BUT, you WILL need to shift higher than peak if you want the best results

Thats straight opinion, not factual. It might work better in your car, but how do you know I will get better results shifting after peak in my car?

i usually shift right before 5k if im just toolin around by myself, but if im racing some one il bring it up to 5900 and leave a little comfort zone between the limiter. im surprised im the 1st LT1 to post up..

This very subject has been discussed many times. Everything I have always read goes along with what I am saying as well. Tony Mamo has said it, and many, many others. I thought it was common knowledge that you shift a little higher than peak to achieve the best results. It keeps you in the meat of the power after the shift is made.

What does your car peak at? Do you have a graph I can look at? What have you been shifting at? Do you use a shift-lite? Let's get this info together and see if we can improve your mph and et

So if people on the Internet that have never driven my car before say to do it then I guess they are right huh?

+1 for shifting about peak. My car peaked at 6400, but stayed flat till 7000 and I shifted at 6700 and this gave me the best results. Heck sometimes I turned it to 6995 and then shifted. These both netted me good results.

When I'm really on it hard i Shift about 6200-6300, haven't seen a need to take it past that yet, is my DD so don't want to blow it up just yet

I guess since your a moderator then YOUR right, huh? I was trying help you, but I guess you know it all already

Me being a mod has nothing to do with it. I appreciate the help, Im just trying to see where you are coming from. You said one thing and then backed that statement up by quoting people on the internet. Me, I like to experiment with what works best for my particular car rather than just take what some says on ther net as 100% true.

Shift light set to 7000rpm

I shift at 6k, I have stock internals no h/c. I think I am shifting at the best time since my peak is at 5500 so I try to stay in my power band.

it IS factual that, regardless of your set-up, if you shift at peak power that you will turn out slower e.t.'s.

old rule of thumb is a 1,000k past peak power is a good starting point.

my orange car's setup peaked at 5,800 rpm on the dyno - best results came with 6,700-6,800rpm shifts.

stock ls1's peak in the low to mid 5,000 range... most shift from 6000-6200 on stock motor'd cars to get the best results.

if your combo peaks at 6,000 - shifting at 6,400 is NOT shifting AT peak power.

this is interesting... your car doesn't respond better to running it out to 7k???

if it's flat from 6,700-7,000 i'd think it would go quicker staying in it's power band 300rpm longer. what's your setup???
