Drive Or Tow It

[grim32]

Hey guys, i just replaced my standard rb20 injectors with gtr ones, had to take 35% off the overall fuel trim on the wolf 3d so it wouldnt blow clouds of black smoke, the af ratio on the apexi turbo timer reads 13-1 with a 4000rpm jab of the gas, dont no how acurate it is but. Would you just drive it nice and easy to the dyno or pay the $150 to put it on a tow truck, thanks.

If it's basically driveable, then I would drive it. 13:1 is not a problem in low-load situations, like driving around town. It's only a problem when you start nailing it.

$150! Is the dyno in another state?!

If you've adjusted the Wolf3D to account for the increased injector size i can't see any problems with driving off-boost to the dyno.

be safe i'd tow it

If it starts and runs, and seems to drive o/k, then driving it will not do any damage AT SMALL THROTTLE OPENINGS.

If it is dangerously out of tune, you will know because of the stalling, hesitations, missing, or jerkiness, and it will let you know something is desperately wrong. But even then it will not damage the motor unless you really thrash it.

It is like running out of petrol. The car coughs a bit and stops. You don't melt pistons, break rings, or burn valves just because you run out of petrol.

Take it real easy, and it will be fine.

i would drive it

BUT - keep it off boost. I had to do the same sort of thing when i changed my afm's and injectors, amongst other things. Added enough fuel so it idled and ran, but i kept way off boost. God knows what would have happened with an untuned pfc, larger injectors and some boost

[grim32]

thanks guys, as this was replied to again i thought id let you no that it drove fine. when the turbo started to spool it was blowing a bit of black smoke so i took a fraction more fuel out and just drove it nice and easy.
