Jeez just pull the string already!

I hope you are going to cut the pipes & put a larger collector on it minimum 3"...
those look very small,or at least run it like that then cut an weld collector & do a back to back test.
I think if you were to leave the pipes as they are you will be severely restricting it.

Can i change my mind?
442HP @ 6500rpm
401 ft-lbs @ 5000rpm

WE HAVE A WINNER!!!

443.6 @ 6500RPM
AVG 4-6500RPM 392HP

411.9 FT/ILBS @ 4600RPM
AVG 4-6500 RPM IS 392.6 FT/LBS

Greg was right..pipes held it back and fell over at 6600rpm.

Good on ya mate.. It is always nice to pull the cord on a new one!
How were her vitals? (oil,water,) Did you get a BMEP read out on it?
Did you get to try it with a bigger set of pipes?
If you cut off those horrible collectors and fatten things up a bit you won't lose anything in the mid range and it should find about another 30Hp @ the top as a bonus you will probably get another 500rpm as well..... Good thing rpm in a track engine ,it gives you a bit more flexibility with gearing options..

Cheers Greg..
