F7P or F7R turbo

[geznay]

thought coops was running approx 9psi?

[Justin..]

dont know

[Coops]

ai mine ran 9psi on normal comp, that was the limit of the map tho, no higher, and it popped!

dont want to lower comp too much either as it gets less n less powerful and looses all torque when off boost

[geznay]

so what boost u running now?

[Coops]

still the same as my clutch was slippin at that psi so not turned it up yet, will be runnin 15psi soon then a proper map at around 21psi

[Justin..]

what does neil run ?

[geznay]

take it you have lowered the compression then so u can run more boost? sorry for all the question but im currently getting all the parts to gether for a f7p tubby and dont know to either go for high boost or low boost conversion

[Justin..]

yeah coops has rebuilt low comp

[geznay]

with 8.5 to 1 compression?

[Coops]

yes, i bought the car with a 10k old low boost conversion on it, it blew the h/g due to chargecooler failure and overboosted turbo at some point. so while it was in bits seemed rude not to go high boost with low comp pistons, its runnin 8.5 to 1 yes.
