what's happened to SE

who are p/r, i would not bother with the 5th injector kit, i had one, it was overfueling a t25 at 18psi and i had the full spec engine that i'am running now, they used a ford cold start injector with a metro oil pressure switch, it came on at 5/7psi, i'd say if you had to use one, have it come on at about 16/18psi through to 22psi on a t3, this would still overfuel, but would protect it up the top end and cool the pistons, i have mine set up to run rich up the top, this is what andy @AMT engines has done, so that i can run a flat out top speed run, this can bugger the plugs up, in japan they run the 300zxtt that rich that they have to change the plugs after every run.

The cold start injector never seemed to add much fuel in my opinion, it only gave out a fine little queer mist. If its designed to enrichen an engine a bit at 1000rpm, I doubt it has much ability at full throttle at 6000rpm. The 5th injector was a waste of time, it did nowt for me.

Why are you having it run so rich at the top end Shaun? You lose power when its too rich.

[s13eater]

its not mega rich, but if you where to run full out on a top speed run for a mile and a quater, its better to run richer to cool the pistons, a lot of the top tuners run rich thats why you can see them poor the black smoke out on full boost, i do more long top speed runs against scoobys than the old traffic light grand prix's against nova's,its just sensible to follow the proven methods ,

[30psi]

Do you know what ratio you are aiming for?

[s13eater]

its 11/6 at the moment but i'am having anthor map made up to run 11/1 for top speed runs.

[30psi]

11.6 isn't too bad, normally the top speeders aim for 10.5

[s13eater]

yep i got it wrong, it was running 11/1 on the t3 at 23psi but with the t34 on 17psi it has leaned out to 11/6, so obviosley it flows a lot more air.
