so we dynoed yesterday. gd took home top honors with 430hp (he has a t51 and a tec2). i'll post the sheet later, but theres something wrong with mine, it only put down 207rwhp (in 3rd) @10psi. george samuels car (attila the fun, the rxx7) puts down 337@10psi. where is my 100hp? i took the exhaust off the the car and i only gained 7rwhp. its totally not what i expected to see, because the car feels faster than; well stock?!?



dissapointed, in ca

only running on two rotors ?

George is running a single turbo, a TO4 or something like that. His motor was rebuilt, and it may have been ported.

Damn, that sure can't be right. Are you getting spark/fuel to all three rotors. What EMS is running the 20B?

ok i found some of it. the engine is good (i checked again), it runs on all 3. this is what i found. the throttles weren't opening all the way, the double throttle blades look like they were being blown shut (i took them out). with just that the boost ws coming on quicker, and it was holding til redline. we also started playing with the timing down low 1000-2500rpms, now it spools the turbo really fast. i think i found about 20-30hp today which would be about right for a stock motor. we might go back and redyno next week.

See, I told you to "open" the motor. Get rid of that double throttle crap! https://www.nopistons.com/forums/pub...#>/biggrin.png
