Fuel Pressure at Idle 750cc injectors?

pokeyl · 05-16-2015, 06:18 PM

GTM 1.5 SC, 750cc injectors, 255LPM pump. Custom tune from Bear383's file custom 82mm pulley (13 PSI)

Items in work - stealth nitrous with remote opener.

When I add the extra fuel with the 750cc injectors I need to make sure the fuel pressure holds. A 50 shot ramped in as a function of RPM (gears 3-6) should produce 650 RWHP and 500-ish torque smooth enough to make the stock internals last.
