DYNO/1999 219whp 184tq @ 10.25psi
Went to the dyno the other day was shooting for 225whp but only made 219whp, It looks like I was still making power up top do you think if the dyno guy went to say 6,700 instead of stopping at 6.300 I could have squeezed out a few more hp's ?

Thanks, thats what I was thinking next time I'll have the dyno guy push a little more RPM's, remember the stock fuel pressure on the NB's is 57-61 psi ( the injectors are 360cc from a 323 gtx but the flow rate is 410 @ 57psi stock fuel pump)

I'am all about hitting the rev limt, but for some reason the dyno guys don't want to do it?

The 99 head flows better than I thought I was suprised I was still making power up top with a small T-25, I made one pass at 11.50psi and lost 18hp so for that turbo anything beyond 10-10.5psi must be in the chock zone ?

6,084 RPM is what my data log shows. maybe he lifted to soon ? I might have picked up a few more hps. if he stayed in it longer.
He told me the pass at 11.50 was 10mph faster than 10.25psi, so does that mean at 11.50psi @ 6,084 produces more mph than 10.25@ 6,300 ?

maybe he meant the 10psi pass topped out 10mph faster than the 11psi pass. but does 216rpm in 4th gear translate to 10mph?
edit: Just checked and that only makes a 3.4 mph difference if you have a 5 speed with 205/50/15s
