Increase Rpm With Almost No Power.

[ARZ 5.0]

Anyone ever had the issue of getting on the gas and having next to no power. Just put new motor in but was also occurring when old motor was installed. Have not had tuned yet I hope that is the issue but can't imagine that much of a difference. Feels like when I installed larger diameter intake on my 05 without a tune. Everything else on the car is pretty much new so don't know where else to start.

Also will my car run cooler with a tune? I had a 160 TS installed and should have stuck with the 180 I think

Love to help you out bud, but you gave absolutely no specs on your car and no driving conditions in which this happens?!? Pretty tough to answer any questions?

...and to be frank, unless you're running a high compression, high RPM, high horsepower stroker/nitrous/FI engine, you probably should have just left the stock 192 degree thermostat in there.

 

[mikestang63]

put the stock thermostat back in. Your car will not run as well with the 160 stat.

Sorry, just put an economy block from LMR with cast pistons. Edlebrock performer heads, Cobra Upper and lower. E303 cam and also Has BBK CAI. Aluminum radiator with dual fans and the 160 thermostat. I don't know what size the mass air is and if the car had been tuned before. I do know in the past this was a drag car that was running nitrous.

I would also recommend changing the air filter. You are sucking in underhood hot air. You are better off with either a stock air box or an aftermarket fenderwell CAI

What's with the wires all on the driver side innder fender and over the battery

It seems to really heat up during stop and go traffic and won't cool down after I get moving even at highway speed which I kinda thought weird.

That's on the list. Which would you recommend?

What's on it for an electric fan?

Don't know what kind but it's running dual 12in hard wired to run all the time. Can drive for more then 30 min with our really getting hot. I'm going to Change back to 192 thermo see if that helps. Pretty sure the 160 just stays open and never gets coolant down in temp.

Run codes?

I had a problem having no power acceleration on highway, turned out I needed to put a working vacuum on my egr valve and it moves out now. My car however runs great with 160 stat

Not yet but I will today. Old drag car has EGR delete on it. I pulled computer yesterday and noticed that it has never been touched. Car has bigger MAF, e303 cam aluminum heads, O/R Xpipe, longtubes. Cobra upper and lower, 73mm TB, etc... So with out being tuned I wonder if it would throw the ECU off that much?

I'm far from expert but I kinda think you have something else going on. Will it run ok when you're not in the throttle? Where's the timing set?

 

[madspeed]

Run codes, check timing, fix vacuum leaks

 

[madspeed]

Have the heads been gone over and valve springs checked? The springs that came on the performer heads were junk

I have seen those underhood air filters cause problems, but usually it causes it to run funny. Air comes off the fan and hits the filter. It goes into the MAF at a funny angle and messes with the computer.
