Ok, so i have been wondering about some things. I really wanna go to a 2.6 and 60lbs etc. etc., but, these popped motors are scaring me. I mean i dont wanna put new pistons in a car i have had for a few months. So anyway, out of all the peeps that blew thier motor, how many were running an Intense tune? How many had water/meth injection? I am thinking that it was the intense tune as well as lack of water/meth to keep the iat2 temp down, any thoughts??

 

There is no guarantee that just because someone else didn't blow their motor, that you wont blow with the identical modifications.

There are so many variables to consider...

The bock could be made with a different lot number of aluminum.

It could be the first set of rods made that day.

The pistons could have a hairline or pocket in the metal that under stock conditions would go unnoticed.


Basically, if you play with fire, expect to be burned.

If you can't afford to replace the motor and you decide to mess with output, then you are truly odd IMO..

 

Know thats not it, if my memory serves me correctly (good luck on that) they all had intense tunes and no water/meth injection. I think im on to something here....

 

BUMP.... X2.... I think i might just stick with the 2.8" pulley for now(going to probally buy a HE and water/meth next summer), I want to do more work to my truck this winter too for next spring..... and need my car for driving to work, and cant afford to have a blown motor..... gm should have an optional race prep motor and tranny.... lol.....

 

bump for daylight peeps, im gonna go be nocturnal now

 

ok list from here...
these are the guys that didn't listen to me on ****, I tuned them for 2.85 pulley's and 42's and they decided to slap on 2.6s without retune (or 60's) against my advice.
1: fractured piston #4 running 2.6 w/42's (I know I know) and meth injection (running everything but meth through it from what I saw)
2: hole in piston #1 same thing 2.6 42's (again I know I know they didn't listen to me)
3: 100 shot on a stock motor melted the pistons
4: broken chain tensioner... just f'd everything up
5: broken cam followers... destroyed exhaust cam and who knows what else
6: I don't know this guy but apparently he was running an intense kit and had a hole in piston #4...
thats just the ones I know of here... I heard there may be a few more. but I don't know the guys..
best bet ... unless you do a head gasket and head studs... stay with a 2.85 pulley... shouldn't be a problem on the motor...

 

It's all about taking care of the car's needs. The more boost you have, the more fuel and spark you will need. Getting a car tuned and having the supporting mods are extremely important in having a reliable car. Oh, some of those supporting mods are gauges to keep an eye on things at all times.

 

In my opinion its all in the tune. Most people that blew up had NO wideband and did have HPtuners so they could not work and perfect their tune as they weather changed some might have been as high as 13s afr and getting a lot of knock. With a safe tune I think youll be okay.

 

yeah, i think im just going to stick with my 2.8 for now.....but you think head gasket and studs is all we need for a smaller pulley and 60lbers?? is that not what started the problems in the first place? i think somebody said the head gasket went and then with the coolant on the piston caused it to crack or something??? does that make any since??
i also see in you sig, you run a 75 shot, i am thinking about going with NO2 in the future, i have never used it before so i will start with a 35 shot first, but is there anything else we should change before we run nos??? head gasket and studs??? i will also be buying a HE, and water/meth kit aswell..... thanks

 

Nitrous kit is in the trunk... just not installed yet... I''ll probably start off with a 50 shot for now .. but once the new motor is in... 100-125 shot for ***** and giggles... this motor for now i going to get a ported head.. ferrea valve train.. cometic gasket.. and arp head studs til the new motor is complete... then the swap and the fun begins

 

I agree 100%, one of the reasons why i haven't bought a 2.6 and 60lbers yet is because, i dont have money for all the other supporting mods.

 

haha, are you going to stick with the s/c or are going turbo or twincharged when you get your new motor??

 

I was originally planning a turbo swap... but I love the s/c... so I think I may run the stock s/c as of now with a 2.7 pulley and 60's with the NO2... then once they release the TVS go with that... should cover my power needs..

 

yeah i love the s/c tooo,, at first i wanted to swap a turbo into it but now I love the sound of the whine .... what is "TVS"???

 

Its the intense or Rob Tune

They are great in the warmer weather, but when it gets cold open your wallet

I will say it again its the tune, and me saying this has gotten me banned from robs shop.

 

im sticking with my tune from meister with the 2.85, 42's and all my bolt ons, car runs awesome, and i have not have had 1 issue

 

good to hear man...cant wait for my tune...............spring seems so far away.

 

im counting the days LOL

 

TVS is eatons new line of superchargers.

 

That's ok though. People need to know that these tunes don't always work, and every car is different and needs alterations to their tunes for their location. Hell, Clutmasters probably hates me too because I tried to help someone out on here, and once my name was mentioned they were proven wrong and had nothing to say. If people put out better products, then we wouldn't bitch. I'd rather wait for someone to put out a good product, than get something that's a piece of crap and ruin everything. That's just my opinion though.

 

its not always the tune... the stock motor can only handle so much abuse

 

It has nothing to do with the tuner. It has to do with you not realizing you have to retune the car for cold weather. A tune made in the heat of summer is not going to work when winter comes.

 

in honesty, i dont think these engines were meant for the power some tuners are hurling at it.

 

Not entirely correct. Cold weather will take a toll on a car tuned to remove the MAF. Our Maf will read higher airflow in cold weather to make up for the denser air, part of the reason IAT sensor is built into it.

Most of the blown motor threads seem to be more the result of dropping pulley sizes and not increasing injector size or at least running a wideband to monitor A/F.

 

What stock HP is SAAB running it???

That is what it was inteded for..
