when i do a full WOT pulls or do two from a stop to 100 my car shows its boosting but it doesnt pull at all feels like its just under the power of the engine alone is this from the supercharger over heating? b/c im going to the bash this weekend and if its over heating after i do a trip down the drag maybe i could throw a bag of ice on it to help cool it down so ill be ready for the next pass any one else experince this?

 

Do you have any cooling mods? Are you running a 2.9 on stock cooling system?

 

Your iat's are getting up there and on back to back to back pulls your car is probably pulling timing becuase of it. I would suggest looking into a nice h/e or dual pass endplate.

I would hate to see your IATs when doing lots of runs. You are probably destroying your engine. Start cooling it off right now.

 

Cooling mods! You are probably pulling a **** load of timing because of heat soak.

This will solve most your problems! I would suggest both!

 

ive been thinking it was heat soak im getting and cooling mods are my frist think on my lis after my tune im getting this weekend but i couldnt never pick witch h/e to go with and i thought maybe meth injection b/c its also a cooling mod ive never worred about them b/c i never race or do pull after pull after pull just 2 and im done most of the time

 

2 is all it could take. I have a 2.8" and I only have meth for cooling and it works real well for cooling. A full pull thru 3rd my IAT 2 is at most 130*. I am getting a dual pass fabricated by my father right now to help it out. then I was thinking on getting the OTT heat exchanger.

But I would def. get the OTT H/E or you could gain some more HP if you get the water/meth with a tune, OTT sells that too.

 

thanks guys i wont have any money for this tell like almost april but i think ill go with the heat exchager since im getting a tune this week and it would be a waste of the tune if i went with meth

 

Run straight water + water wetter in the cooling system. Dexcool FTL.

 

Cooling mods....

Meth
A heat exchanger or
the dual pass endplate

You need 1, 2, or all of these and your car will thank you! At a certain point the car will start pulling timing making it as slow as stock!

 

I agree.. Since you are in Texas you can get away with using 100% Distilled Water. Thats what I run. When you have a 50/50 mixture of glycol and water the cooling efficiency drops a good amount.

Since you say you wont have the money for the cooling mod, do this, and take it easy in the summer.

If you dont have it, a good investment is an aeroforce gauge to monitor that stuff. That will let you know that your IAT 2 is sky high and your motor is hating you. lol

 

well i plan on getting the H/E for sure but im getting a tune this weekend and i would have to get a retune after the meth and that would take a while

 

That is true, so get the 100% distilled water in the cooling system so you can drop the temps a little.

 

Heat Soak is murdering your car. Get that fixed.

 

its not killin my car i dont do WOT very often and if i do its never all the way through third gear and my coolent never goes over 182 F but i dont have the funds for cooling mods right now so its going to take some time to get some

 

so stop being retarded and cancel the tune and buy a dual pass endplate this will solve your heatsoak majorly, also get a tank and fab it up, both can be done for well under 150....

 

H/E is ok, But you need a dual pass endplate to cool that thing down! Do the dual pass then get a front mount, it will benefit you much more!

LOL yea its already heating up & with a tune it will be more!

 

im getting a tune from trifecta for 200 im not passing that up and the cooling mod is another 50 more then that so ill just get the tune and get the cooling mod later it wont hurt the tune at all and i cant fab stuff no welder or anything

 

Coolant temps & Intercooler temps are 2 different systems, do you have a wideband reading your IAT2 temps? If you do & your temps 182 well I need not say anymore!

yes it will depending on the tune it will pull more timing & you will have Knock like hell! Kaboom!

Cooling is must & with out it......well just look up some of the old threads & start saving money for a rebuild!

 

if an endplate is bettter then ill get it first then the h/e and no i dont have a wideband

 

you don't need to fab stuff you can get a dual pass endplate for around 175, get your 75 back when you return your stocker, buy a 10 dollar tank from autozone and make it into an option b tank, problem solved, simple crafting and mechanics
.
do you want a blown up enigne that had an AWESOME TUNE!!@!@#$@!% for a few days or do you want an engine that loves you that will wait for a tune?
your choice not mine..

 

Then the temps you are seeing are engine coolant temps.....Not intercooler system temps! but guessing I bet they are close to 180 with no cooling mods & a 2.9 especialy after I hard pull! By comparison my temps w/2.8 & complete dual pass & front mount in 95 degree weather are 120 after 4 hard pulls & as soon as you let off the temps start to fall back to just above outside air temps! This allows you to run more timing & get more power out of your tune!

 

ive been running my car like this for almost a year now like i said i never do much WOT i do like maybe one ever two weeks for the lenth of a block and i drive my car from school to work witch is 5 blocks and then the 4 hour drive home about once ever 3 months but i dont do anything that going to make it blow up i dont push my car at all so would i really blow it if i just got the tune then baby it for the next month?

 

Why does everyone here seem to jump to pointing fingers at the biggest problems first?

I would agree that a HE and dual pass would be nice on that setup, a retune though?



Check your intercooler pump.

 

That's your choice not mine.

My opinon on it though, you don't know what temps your running, you don't know what your a/f ratios are, you don't know when your cars about to blow..

If I were you I'd say **** the tune and do cooling first, that's what I'm doing, and I'm sure it's much more warmer where you are than up here in PA...
