T76 Turbo Cobra

[shts_weak]

You are correct sir. There a work of art

 

[s351]

Did you up the boost or, what went wrong with the motor?

 

[shts_weak]

went from a T4 76/75 now running a T6 80/96 so its not even a comparison lol. piston slap

 

[s351]

The piston slap got that bad you needed a rebuild??

Man, I have not understood much of this thread past the first post, lol.

 

[shts_weak]

I blew the head gasket and it started making a knocking noise from the bottom end. so i pulled the heads off and the pistons seemed burnt from always running e-85. usually e85 cars have cleaner pistons and there was barely any miles on it. sent the block to the machine shop and was told it needed a .020 bore to get the scratches out. the block was already bored .020 already so he recommended me switching to either another normal iron block or get the boss block. so i did.

 

[s351]

Ah ic, I was just curious on why the stocker let go on e85, e85 usually saves engines.

 

[shts_weak]

yea i was surprised myself. i guess it was from detonation? as soon i get everything back together, I've been speaking to Jon Lund and I'm most likely to tow the car to evolution performance so he can tune it.

 

[s351]

The tune is everything on these cars, a guy torched my ported eaton setup, now i'm almost finished my built motor, hellion precision 76 setup, and i'm terrified of going back on a dyno, shooting for 700rwhp on pump 94.

 

[Turbo98]

I'm surprised you went with a 3.72" bore right off the bat. That basically gives you very little room for a rebuild/freshening up.

 

[shts_weak]

spoke to tim, its a 3.700 my bad fellas

 

[Turbo98]

Whew, that's better!

 

[shts_weak]

Good news! pistons finally came in last week. Everything is getting balanced/assembled on monday!

 

[svt4me38]

Did you get to make any clean passes in this thing before you hurt it?
Believe the fastest Jeremy went with it was 6.4x-6.5x 1/8.

 

[shts_weak]

No track runs, just street pulls...I ran a gsxr1000 and gapped it pretty bad.

 

[crfrider16]

I bought a built turbo cobra several years ago and popped the motor 6 months later myself, so I know your pain.

Glad to see you're building it bigger and badder though! I followed the build thread on your car. Beautiful car!

 

[shts_weak]

Thanks Bro.

Hate to hear your having to rebuild the whole car so soon, you don't seem to upset about it though lol.

there should be a new forum section made for all those who have been unexpectedly forced into rebuilds such as myself...misery loves company
