Quote: | ...At QLD jambo we made 380 rwhp at 17psi. we were making 40 rwhp per pound on anything over 14psi. (i have a 14psi spring inthe wastegate). i was at 97% duty cycle on 550cc injectors using 45psi rail pressure. it ran a best of 119.46 MPH on the 11.8 run. but averaged 118.5 MPH.
next outing was compak attak, we changed fuel from c16 to sunoco. we picked up considerable torque gains but power stayed the same. for some reasaon the power would drop off after 4375rwhp. which later was found to be a slipping clutch in the converter(confirmed by MV automatics) at compak attak it ran consistant 118.5 MPH until heat soak settled in on elimination rounds as they were run back to back. all though coming runner up in this event i was disappointed no to run in the 11's again due to the stall issue. watching the footage it was clear the car drove 40 metres or so before seeing any reasonable boost.
after getting my tax return cheque i had some money to improve things. we decided to up the injectors. i went with rochester 1000cc injectors as they were $50 cheaper per injector than 850cc's and i didnt have time to get sard's from japan. with the added fuel now we could increase boost pressure to 22psi. again we made 40 rwhp per pound except on the last pound were gains halfed.
this is where the addional horsepower came from. the NOS is used soley for the purpose of getting the car on stall. which is commen in the drag racing scene where big convertors are used on small capacity engines.
ANDRA sport compact rules state that in my class of SPORT RWD/AWD i can in fact use NOS and as much as i like. i am contemplating changing the setup and using the NOS the full lenght of the track. this should help drop times to low tens.
SKIP- yes i believe trying to squeeze this power through a 60mm hole is a definate restirction. i may look at HARDCORE RACING's stage one head in the near future, with a 7 litre plenum as well.
thanks for all you well wishes guys, i appreciate it. again if anyone has more questions i am more than happy to answer via PM.
