very nice what mods ? no sig
|
do you have a pic of your engine bay. I'm about to get the greddy FMIC,but have a blitz intake. I'd like to see how you have your intake
|
any fuel upgrades? are you running a ported motor? are you controlling boost with just the pettit ECU?
|
I can take a pic tomorrow, The intakes are really tight.
|
supra fuel pump, boost control via needle valves. stock reman.
|
very nice. are you maxing out your stock injectors?
|
in your sig it says "best track time 8.19 @ 86mph".... what distance was that, im guessing 1/8 of a mile?

its 1/8 mile. no way u can run a 8.19 with a trap speed of 86mph :)

Re: Re: dynoed my car today
Originally posted by patriick Nice numbers at 12psi, especially for a non-ported motor. What were the conditions? (temps, correction factor, 18" wheels?, etc) Ive been trying to download the dyno chart, but the file is too big, I will have to try to get it hosted somewhere. I can e mail it to you though. |
dyno chart finally
|
anyone know why my power drops so quickly after 7k?
|
actually...

on the 14 and 16 psi runs, your in the blow the engine range for the A/F. I'd keep it at 12 for now.

Only one question guys, is this rear-wheel or flywheel HP?
|
nice numbers
|
rwhp on the dyno.
was the boost stable during the run? If it's dropping off, then the HP would too. Tim |
boost was stable until redline, I guess the turbos just lost their efficiency
|
okay, looks like its the ecu mapping that is killing your top end. First, I'd add some fuel, if possible (S-AFC) from 5500 to 7000 RPMS. Then the drop off after that is due to the extremely rich mapping, 10.0 to 1 it looks like from 7K to redline. The engines greatest stress is leading up to peak torque. That looks like its 11.0 to 1 from the map, kinda small as far as telling from the scan. With my PFC, I was in the 10.3's heading up to redline. I took out as much as 8% fuel (from about 6K up) and the peak HP went from 339 to 363 and stayed under 11.5 up to redline, until I let off near redline. An ignition amp might help light the mixture as well since its so rich, it would lean it out a bit with it burning off more than stock.
