What were the conditions like when you ran the 12.0@114mph and what tires were you running? DA? I know there are several factors that come into play but just wondering cuz i figured you'd trap a lil higher w/ 399rwhp. (Not dissing, just curious) Did you data log it during the run?

No logging as I didn't plan to run that fast. I still had some tools in the car and my heavy body Coddington wheels on front. Car was NOT track ready at all.

I don't know the DA but the run was made on old worn out nittos and I could feel the spin from the launch. Unfortunately the worn out nittos are all I have right now so they'll have to do. The car has trapped as high as 117 before but these are my first few passes with the new converter and gears so I'm still working on the launch.

You had it ground on a 110 for you? Or, is it off the shelf?

What race weight were you at? MPH looks real good, what heads were you running?

Thanks for the info,

It Was Off Of The Shelf From Thunder Racing.....studytime

Not to be rude, but the exact LSA is a little wider than 110 degrees. Instead of just picking a few lobes from a spreadsheet and then picking a LSA at random, TR designed this cam based on valve events and let the LSA be what it was. It actually worked out to around ~111 degrees. For this cam, unlike many others, LSA was a dependent variable based on valve events instead of a bandaid to fix excessive overlap.

Not all combinations of the 230/224 are optimum, and there is a set amount of variability associated with any cam's results, but a trap speed at 122 MPH for a MILD cam-only car is nothing to sneeze at (VIPRETR2's car, 3500#s).

I like this approach to laying out a cam better than just picking a pair of lobes and putting them on a "fuel injection lobe seperation angle".

Steveo346, I applaud your choice.

I ran mine about 2 yrs ago. I went a 11.90@119 with cam only and bolt ons. I put 398 hp and 372 tq with the stock tune. Car is full weight other then running skinnies and no spare tire.
