How many went FI and blew a motor?
 
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. :rofl2:

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

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

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.

Sharpbycoop blew his motor because his RPM was at 8100 while his oil pump system was stock.

You should never mess with Redline RPM before getting the right oiling system to the engine.

Other motor that blew from FI were stillen SC, the fail was from tune and kit it self. (if you want more power go for off road SC which is GTM, but if you want CARB Legal kit then go for Stillen and keep it as it is for god sake..)

I hate seeing people bashing on a kit because they wanted to extract more power from the SC. Go to Stillen Website check the horse power that your car will make with their kit (500 BHP which is around 400ish WHP) and if that achieved your needs then go for it, if not then that kit was never for you and you should blame your self if anything goes wrong with your car after messing with the kit. it's simple as that.

last but not least. Tune is the key of longevity. A bad tune can blow a stock car.

I couldn't have said it better myself.

Nothing is wrong with the stillen kit and if you live in California there is no reason not to get it unless you plan on making your car 100% track.

I do feel though that you could change the stillen kit up a bit but with stillen/vortech parts, like a vortech impeller and stillen's 9lbs pulley and just make sure your tuner knows what they are doing and you have a rock solid tune because like you said, a bad tune will blow up your car, even if its stock

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

Sharpbycoop said in his post on MYG37 that he wasn't convinced that the 8000 rpm rev limit blew his motor,and I'm not either. I saw and spoke to Jimmy the owner of the shop that built his engine ,let's just say that the engine wasn't blown from high rpm.

I can be added to the list of blown motor with my old Stillen Supercharger set up cylinder 2 piston wring went. A friend of my with a GTM TT 370z Nismo also shot a rod right out the side of his block at 550whp 12.7 PSI of boost after beating on the car for 13k miles.
