Cobra motor(w/65mmTB)+FREE 70mm TB=?

[CobraWannabe]

On my Cobra motor I have a stock 65mm throttle body. My brother will give me his old 70mm, and I was wondering if its worth any gain in horse power.

Thanks

Sence its free take it. But depending on whats done to you car it wont make much of a difference.

The TB opening on the cobra is only 65mm, so you won't gain anything, you actually might lose a little bit with the switch to a 70mm. Unless the intake has been opened up a little bit, I think you should leave the 65mm on there for now.

I actually think the opening on the Cobra intake is 70mm.

With what you have, you prob won't notice anything. Ebay it and buy something else

Keep the 65

I figured. Thanks for the advise.

Put it on and sell the 65mm. It will only help you as your car grows, it won't hurt you.

I had a pretty good motor and I still feel my 70 TB hurt my 89. Keep the 65 TB. Unless you're around 400 HP, then use the 70
