Trust the Process Luke.
If a competitor requests a car be classed in a second class just run it thru the process with the new class power to weight and call it a day.
Trust the process.

Nah, I just speak for one IT racer. I have no idea if anyone on the CRB or the BOD would share my opinion on this. Probably only one other person on the BoD that has much of an understanding of the philosophy of IT, maybe two. The CRB of course understands us a lot better.

Spinnetti, in reguards to your build it sounds that your mechanical engine is close to 100%. Mine sounds identical except runngin lowe tension gapless total seal rings, and I did play with the bearing gaps. Coatings are illegal per IT, so no coatings.
what you are missing is the additional stuff. For example I do know that (depending on what TRD header you have) you can gain a few ft/lbs but probably 0 hp going with a different design. I have had burns run a simulation for the the 4AGE with stock cams, cam timing, and port flows. From my understanding they typcially do not do this for free. I calculated using mathmatic calcs using sonic and mass/velocity/acceleration equations (keeping the speed of sound constant with temperature). It parralleled what burns came up with and you might be suprised.
Luckily the stock computer is fairly aggressive.. even with a tuned header the AFR's are really good, which is probably why you saw little gains with changes in FP.
Engine is odly EXTREMELY sensitive to base timing. 2* either way off the optimum timing is 1-2 hp peak 4* you can see a change of 4 to 6 hp.. This is alot for a car that does not make much to begin with.
In reguards to the intake side of things.. this has been tested many times and documented on line. If you want to test yourself get two ferncos and play with piping lengths.. once you the best make a permant solution. (Though it has been found for the 4AGE LP engine that shorter=better for peak hp).
