Dyno Tested

[stickman]

I went and got my car dynoed today.I would put up the graph,but I don't have a scanner.The car is running lean,and I hope to fix that this Saturday,Anyway here are the results:

HP---124.3@the wheels

TQ---116.6

By the way,does anyone know the best way to richen the fuel to air ratio on the 420a???

The car was running lean? Well don't raise the fuel, get something fixed. We run very rich N/A.

What kind of mods do you have? Those are some decent numbers actuall for being N/A.

well your profile says you have an intake and exhaust, and those numbers are pretty good for just having that. And you ran a 15.2, what was your 60' time

I also had my head rebuilt(larger valves and such),but the car has 104,000 miles on it.Any clue on why I might be running lean??

I really dont know too much about fuel systems, but the problem could be your fuel filter, or maybe your injectors. On a car with that many miles those things need to be serviced

I don't want to start another thread so if anyone can help with my problem that would be great...

my gs was running lean awhile ago too...i pulled off my fuel rail (after i checked the fuel filter and pump pressure) i cleaned the rail, the injectors and the " pressure regulator" bypass/ return line. after it was all clean and back together it ran great! there was a sh!t load of varnish in everything. it takes about 2 hrs and it really sucks.....solved the problem though!

You could try a new fuel filter, or a new set of injectors. We all know that lean means too much air, and not enough fuel... which is a bad combo. I would look into finding out where you are lacking fuel. Fuel preasure is the key. I would see if you are providing the fuel flow as your engine needs. Now with a rebuilt head with larger valves, your engine requires much more fuel. Your ecm might not understand what is going on. Try taking your battery terminal off, and putting it back on... sometimes that resets the ecm.

I can send you a brand new fuel pressure gauge if you send me $38.50
