With my IX build underway, I am considering going to a more aggressive camshaft than the 272/272 Kelford combo I had before. I loved that setup, and it made great power and performed well, but it still seemed like too much of a street cam. Lana, the car I bought from Most-Wanted, will get driven on the street, but most of it's time will be at the track. I don't care about driveability that much, as long as I can get it from point A to point B.

My options would be going to a 280/272 setup, or the straight up drag racing cams at 282/282. Specs are here:



Looking for first-hand experience here. The car will be run on the stock turbo trying to chase down the 10.2 pass again, and then stepping up most likely to an FP Black, to stick with the stock frame for some more shots at records.

Please lend your experience, and let me know some problems with going with such a big cam on a small turbo. We'll be running E-85, 30+ psi, DI manifold w/ Hypertune TB, and at least 1600cc injectors.

Thanks!

The Kelford 272 is plenty of cam for your set up . On a customers car we made 700 whp with a PTE 6262. The 272 is on the large side for a stock turbo to begin with the 280+ cams would be over kill. There maybe some gains to have up top with a 280 cam on FP black but i think it would give away too much down low to justify it.

 

Do you know of any dyno graphs to prove this? I've heard both ways, but I haven't seen any data to back it up.
