18PSI or so with methanol inj. and shell V-power. Royal purple fluids. Oil pressure looked good and running super rich at bout 10.0 AFR. From a stop i shifted at bout 8k and went through the gears till bout 5500 in 4th. all the sudden i lost power and the engine has a completely diff tone now. i havent done compression test yet but im almost positive.

So now i guess im having my friend at school here who built that engine in the white FC on pinks. Hes gonna do a mild bridge port for start and im gettin a pretty good deal.

 

That's way way too rich. That has a REAL REAL good chance of blowing spark out. That'll induce knock that can break an engine.

well rx7store tuned it so whatever. my luck

 

could have just fouled up your

 

What kind of vacuum is it pulling at idle? Will it hold an idle?

 

im not sure what kind of vacuum. but it holds an idle barely. give it a little throttle and it bogs and wants to die. im thinkin i jus popped like 1 seal or somethin. the car is an hour and a half away right now so i cant check for sure till like friday.

 

but speed machine performance built the car that was on pinks, in california

 

do the easy test and pull front leading plug, turn it over and listen to compresion faces... then do the rear... ( make sure to pull the fuses so no fuel is pumping out) Quick and may tell you if you lost a seal. If that checks out do a real comp test....


best of luck..

 

We tuned it for 10's ? Typically shoot for mid 11's unless there is an issue with the car. How long ago did we tune it?

 

last fall you tuned it jason

remember it left the shop bogging out at 6k rpms and intercooler piping shooting off into my hood? lol

I prolly drove it 4-5 times after the tune b4 it blew

 

Check the vacuum hose going to the MAP sensor on the Microtech, 18 psi blows of hoses that are not secured quite easily. This will also make the car feel like it has a blown motor.

Did you have the map sensor upgraded to the 3 bar internal unit so that it could read 18 psi?

 

I sort of remember your car just from looking at your avatar, but dont remember what was going on when we tuned it. I typically dont tune a car for that low A/F so there must have been some issue while we were tuning it. Were you running staight Meth or a mix with water?

 

straight meth

 

Im not sure cuz i didnt install the microtech, got the car that way. ill check.

 

I would also suggest checking the plugs first.
