Up Pipe

[cmokem]

Are there any gains to be had with a larger uppipe using a stock location I/C or will a big uppipe actually hurt the performance

TIA
Happy Thanksgiving

No advantage if your still running the stock size throttlebody. It might work with a 70mm. Once you go to a bigger pipe, going back down at the throttlebody wouldn't be a smart idea. I've seen it before but can't see how it would work better than the same size pipe.

Would running a bigger up pipe increase spool time of the turbo??

Mine didnt. Went from stock to PTE IC with 3" pipes, and if anything, it spools better
