Street heat or track heat

Kponti · 11-24-2001, 11:01 AM

In my opinion, go with the track heat. I have a friend with the track heat on his car (SN95). He currently has a 331, but when he had his 302, he was running the TFS heads and stage one cam with the street heat. His best was a high 12 @ ~103-104mph, he switched to the track heat (exchange with another guy he knew) in anticipation of the 331. While still running the 302, he increased his trap speeds to a high 105mph with just the intake change. He is now looking for a better intake for his 331 (hate to tell him, but I told him so)

The #s on those intakes are for marketing and usually that only. I was told time and time again that my intake was too big for my application, but I sure had a smirk on my face when I was pulling them. TFS also told me my valve springs were ok for my application since I was not reving past 6000rpm. Well how about an ~(calculated)3-4mph increase with just the valve spring replacement.

When they say an intake has a certain rpm range, it usually means where it would like to make the most power if all else was stock This always not the case ofcourse, but I have come to find out this IS the case with the TFS products.

I would stay with the intake U have now till U get all the other parts ready to be put in. BTW the TFS street heat WILL NOT make ANY power over the Cobra one, in other words a waste of money.

Sorry for the long winded one
