How many went FI and blew a motor?

FireDan50 · 10-03-2013, 01:57 PM

I've been going through all the builds and trying to see who all went FI on a stock block then either blew an engine there or built the engine and blew it on forged internals.

Can people post up if they blew their motors on boost and add info on details of the destruction: single/twin/supercharged, boost level, hp-torque numbers, number of miles on boost, destroyed on dyno/track/street, bent rod, melted piston, etc etc.

I'm trying to get a better picture of just what this motor can handle and see where things are failing.

The general consensus is that over 550whp, you're playing with fire. There hasn't been too many people who have popped motors (and all of the ones I can think of offhand were Stillen kits), but not too many people are pushing the stock block like you are. Sam at GTM told me 500-550 was safe, over that cylinder pressure starts to get iffy and you run the risk of a bent rod.

FireDan50 · 10-03-2013, 02:16 PM

Yeah, I haven't come across many boosted blown motors on here and I definitely do not want to be added to that list. I'm really curious about what hp/torque levels people were at with blown motors and the circumstances behind.

Chuck33079 · 10-03-2013, 02:17 PM

Considering you just jumped into the top 5 of power here with that dyno run, you tell us.

FireDan50 · 10-03-2013, 02:22 PM

Oh my engine is still running strong...fingers crossed. I'm totally confident with my tune. I just want to hear from others who may have blown motors.

There was a couple gtm cars that popped but they were way up there in whp. Like 600

I have heard of a few motors blew on the GTM supercharger, but that was like last year when I first joined and asked about stillen vs GTM(I'm not digging up that thread lol)

Most of the ones I hear about though are stillen superchargers and iirc, they were either modified and/or installed improperly.

AFAIK, no TT kits blew any motors yet

What is "as far as i know for a fact"? that's like saying "hey I may be wrong, but I believe I definitely am alive". lol

I like it it's going in the sig

blackonorange · 10-03-2013, 03:53 PM

There was a black g37 with lime green wheels I think bullit owned it. And coop bent a rod to at591 whp but he caught it before it blew a hole in the block

elperuano · 10-03-2013, 04:00 PM

FireDan you guys did 1 pull correct for the numbers? Christian n another GTM guy pulled those numbers on c16. Race gas allows for waaaay more power.

im at 534/500 stock block 12 lbs over 10k miles. No problems at all. Jist little minor things. Motors r strong.

We did a few pulls to get up to 611hp. Started at 530hp @ 7.5psi. Then went to 580hp @ 9.5 psi. Last one was the 611hp @ 10.5 psi. We were so close to 600s we turned up the boost just a little to see the results. Only reason I decided to chance it was because I have total faith in Todd Marcellini's tuning skills at Motion Lab Tuning. We decided it was best that we stop there lol.

Be advised if you didn't see my build thread or read elsewhere, these numbers were achieved by using Q16 VP race gas

What setup do you have, if you don't mind me asking? You are making awesome numbers on such reasonable boost levels!

I'm trying VERY hard to make sure my GTM setup will be the same - lots of power on less boost. Coupled with a good tune, I have complete faith in the VQ motor.
