Where would be optimal for a large cam such as a btr stage 4 to be shifting with all supporting mods such as headers, exhaust, and intake? On average. Currently I am shifting at 6500, would I gain a bit by moving my shift points up a couple hundred? I don't have access to a dyno but I know the cam should easily keep gaining power way past there

 

What intake manifold? I shift mine at 6800-7k

 

With the setup in my sig I shift at 7000 and it pulls the whole way. In a perfect world I would run mine to around 7200 but stock rod bolt life here.

 

Intake is just a fast 78 at the moment but I don't think it. Would really hold me back as of now with the 853 heads. Tuner has me shifting at 6500 right now and I'm running the 1/8th mile @7.1 wanting to hit 7.0. Right now a few feet in front of the finish line it shifts into 3rd so I have a feeling raising the shift points to 67-6800 will help a lot

 

Bumping up your shift points from where they are now will help. That cam is huge and not ideal at all for your setup. How tall are your rear tires?

 

26s and it's one of the best cam only shelf grinds, plus my 4000 stall is enjoying 1.50 60fts so I don't see where you get that logic from.. It's running 11.1s shifting at 6500 cam only right now.. Seems like it's doing decent lol

 

For a c5 it runs okay. The logic is that cam needs 7200+rpm to be relevant over a smaller cam. Your heads and intake can't support that.

FYI I'm looking at 1.5 60s with more weight, less stall, and less power than you this year.

 

Lol@ for a c5 it runs OK.. Post up a timeslip.. I go off real results not internet results

 

You don't see many cam only ls full weight cars running what mine does.. And I beg to differ that a fast 78 isnt enough for a cam only application

 

Oh you run 11.9.. You, have a ways to go before lol. .. Not to mention I'm stock suspension, stock weight and less intake than you yet a second faster lolol

 

You seem upset but it will be okay. Your cam has 16.5degrees of overlap and you shift at 6500rpm. Take some time to understand that and type "lolol" some more because you're making me laugh

 

i guess you missed what this thread was about. I am not the one that tuned the car.. thats why the shift points are getting changed -.- and you are still slower than a less modded oversized cammed car shifting at 6500..

 

You should gain quite a bit moving up your shift points op baring you have no choke points in the intake and exhaust tracks SXCZ28 is right in the fact that cams happy place is just above 7K. What stall and rear gear do you have OP?

 

The thread exist because you didn't know 6500rpm shift points were bad.

 

 

Car runs strong imo!! I bet it picks up if you shift it higher.

 

Thank you, I hope so. Just glad it's not a slow bolt on car barely hitting 11s

 

I would say if your shifting before the traps to much it's not helping anything but you can shift it just before the line, the force of the shift will give you an extra mph on your slip and a little e.t. Then try letting it rev more and more till your going your quickest. Every car is different. Yours is lighter than most indicating a little higher shift point than most but it's not always the case.

 

Sorry if I upset you man. Tomorrow is another day, best of luck.

 

Is it an a4?
