I finally got my turbo fixed. I drove my car a couple times and it quit smoking. It builds very good boost, around 27-29 psi. But the power seems to level off at around 12-15psi. Im still running the stock pump which is like 88lph or some wimmpy stuff. Does anyone else think that it is just leaning out? I mean at 29 psi the car should be going nuts shouldnt it?

You need to get a 255 lph in there soon! Ask coupe if he still has one. Your car is gonna run lean!!!

is anyone else using the hy35? so when i put the big pump in should I see a huge gain in performance. Also, i want to get rid of the factory rev limiter, i dont like the idea of cutting fuel. Im going to let the MSD handle the rev limiting. Who is the best person to talk to about that?

I don't know about a huge gain but it will keep you from running lean and blowing the motor.

You know, I hear this a lot. I don't buy it. If this were true, the manufacturers would not put this style of rev limiters on all cars. Cutting fuel completely off is not the same thing as running a lean fuel mixture.

I like hitting the rev limiter. Makes me proud!!!
Injectors, fuel pressure, A/F.
My first setback was fuel on the dyno. Had a bad regulator. Then I replaced it piece by piece. power will fall badly and seeing the dyno guy lift at 4500 rpms lets you know you have a problem.
255 pump is about $112
AFR is about $80
42 lbs injectors $220
30 min's on the dyno will save you $$$$
Then your next upgrade should be brakes!
I have had the timing off enough to do that also. Never hurts to check everything,

A bad plug wire will drive you nuts!!

I checked the cam timing with a string, dead on. But i did check the ign timing with a light and it was only set around 8deg. I turned it up to about 12 and went and drove it, big improvement. So ill keep tuning on it. I want some bigger injectors, but i dont think im ready for that yet.

Running that much boost, you really need more fuel. Get the 255lph pump and at least a set of 42's...you'll be safer.

were is the best place to get bigger injectors, and a chip burned to use them?

They need to be low-impedence. I can get probably anything you need, but let me know what the chip is going to be for... There's a couple folks here who play with chips for these things. I'll let them chime in. :nice:

Replace the fuel pump. Do the 42# injectors and adjust the fuel pressure. THe chip is a lot of leg work unless you know the guy that does it. My guy is in texas and it was $125 for 2 days of leg work and the 3 trips to the dyno. BUt I am happy!!!

Then you could do the stand alone and be very very happy!

i have the LA2 computer, big vane air, and im going for like a 46 or 55 lbs injector. Id like to either do a blow thru meter or just convert to mass air. I dont like having the meter in front of the turbo, i feel like its a big restriction.

It's better upstream than downstream of the compressor. If I'm not mistaken, the VAM can support around 400rwhp before it chokes. I've seen well into the 300's with them.

Same with coupe. Of the wide bands I have seen it was a little harder to control the fuel and had some power control problems as far as the pedal. trailer hitching, bucking as you let out of the throttle. And of the ones that changed out of the stock eec and went with stand alones the power pickup was surprising. Thats where you get a good tune and the engine is working all the way instead of being held back by timing and fuel.
Nothing looks better than a 12 to one straight across as the rpms go up.

Stay stock and upgrade the fuel, injectors, turbo, intercooler and you should hit 300 easy.
That means valves, rings, and cam are in good shape too! Bent valves will hurt your feelings. I know.
upgrade eec and get the right tune. then smile.

i set my VAM up like you are talking about. Stinger on turbo ford built my program for the blow through setup and it worked good. But at the boost you are wanting it will blow the VAM up!

i ran the 42s out of the the 83-84 ford thottle bodys with stock set up computer for a while with fuel set around 40 psi with no problems at 20 psi.

Ok thanks for the tips. What is program is best to upgrade for the injecor size with. Tweecer or just use the moates stuff? The tweecer rt has datalogging. I know a guy who is a SCT dealer too, would it be better to just let him handle that part of it?

What every you get you have a long learning curve if you want to do it yourself. I tried to find someone to do mine. Took a while (1 year) but it got done.
Moates is a cheaper way to do it. But you have to have software, datalogger. dyno time, programer.

Best, way to do this is find someone that knows how to do it and pay them. I have been out of the loop on programers for a while. Holly commander or sds has been the better of the programmers.

The datalogger was a good thing to have but after you do your tune it is no longer needed.
Dyno may be cheaper with someone there to do the chip burn. Look in the http://www.streetstangs.net/forumdisplay.php?f=21 and see what you can find.
