Sorry, we are not going to locate and set cam timing specs for 300 different cars.

The Mustang makes damn good power so it got a higher gain number.

We don't run all cars at the same gain. We run at 25% as a default with different default numbers for rotaries. We move off of the 25% if we have good data showing we should.

To run all of them at the same gain is not going to work.


Take the 4AG, the factory left very little on the table at stock cam lift and compression. Small gain indeed. The 16V VW is exactly the same as the 4AG. Very small gains . The stock exhaust manifold works very well with stock cams and compression. The biggest gains for both of these cars is controlling the fuel and timing map at race RPMs, after getting all of the legal compression and freeing up the rotating mass.
No way will either car make 25%. More like 8-9HP total .

I will go back to lack of cam timing rule for the IT cars. SM has gone to a much more hard value for the cam timing. For good reason. . We have guys moving the cams in the head to move the timing. Milling the head retards the timing and makes a little more upperpower. Maybe 3hp from 4800- 6400 on the VW.
The current rule states that the cam timing may be returned to stock, or may not.
If you allow milling the heads and decks. It only make sense to allow the adjustable cam wheel specifically to set the cam at stock spec..
Spec the valve opening @ stock plus or minus 2

ITAC needs to come up with good data for the cam timing, not leave open, as it is now.
Pull some valve covers, make shit happen.
I run the VW IT engines/cars that I have bought, in HProd. I usually have to reduce the cam size.

What happened to the Ford Mustang, with 88-96 HP how did it end up so heavy?

The SMAC has some vested interest issues maybe.. I put in for allowing replica (500$) tops that weigh the same, look the same ,etc .

"Not needed as tops are easy to buy" BS the SMAC guys own the legal tops and sell them for 1000$.
The HOHO tires are running off a lot of those guys now also.
