Blown 93 Cobra owners...in here please.

[~Ray~]

Just curious if you've ever had your car on a dyno. 331 and a Screw blower must put out some insane off-idle torque. Bet it's a beast on the street - if you can hook it up....

Many times. I'm constantly upgrading, my current combo I have not dynoed yet "but plan to in the next couple of days" but before Heads, Cam, Inlet, Added Flowzilla boost, Headers, Tweecer, etc, etc I made 441/565 to the wheels, I'd guess I'm around 500 to the wheels now, if I could stop blowing head gaskets long enough to get it on a dyno :bash:

What type of head gaskets are you running? O-ring'd the head yet?

 

[~Ray~]

I've ran all the graphites & Cometics, the Cometics worked but leaked oil everytime so I'm back to the 9113pt's again.

 

[19COBRA93]

I was most successful with the 8548pt2. But, I never tried the 9113's.

 

[~Ray~]

There the same as those just the 9111's have a steel firing ring where the 85's are a softer metal.

 

[19COBRA93]

That's good to know. When I've had issues, the firing ring has always been fine. I just get compression pushing past it into the coolant jacket which burns away the soft gasket material just past the firing ring. Basically the heads lift slightly under extreme pressure. Something the stock GT40's are known for. I've learned a little over torque on the heads helps a lot. I torqued mine to 90 lbs lower, 100 lbs upper) with ARP's and they seem to hold with up to 21 lbs. About once a year though I'd have to replace them. I also ran Alcohol injection which helped a lot.

So what about the 9333's?

I love hearing about blown Fox's. Can you guys post up some vid's and pics of your Blown 93' Cobra's??

 

[~Ray~]

Sorry I meant the 933's "not 9111's".

They are basically the samething as the 845's "or whatever" & Fords b50's. I cracked my block just found it today so am ordering a new Dart Block tomorrow & may try the Cometics again since I'll have a smoother deck this time.

So how much horsepower is that thing putting out now with 12 psi? Thats basically the same set up as mine, although my $hitty powerdyne only managed to push out 7 psi on a good day, so I only saw 451rwhp

 

[TERMIN8TR]

well on 5lbs of boost (lots of belt slip) it made 450 rwhp at approx 5000 rpm's.
the belt slip issue is taken care of and now he's seeing a consistant 12 lbs. the car goes back to the dyno this weekend. should make 550rwhp +.
that motor made 900 plus on 25lbs of turbo boost.

What cam is that ?

Taken from another thread where John put up the specs on the motor

"Well, hopefully when i take it up to the dyno this saturday there will be NO surprises...lol. Im still not sure on how much power its gonna make though. Kinda long story on the engine but here goes....The guy that i bought the motor from got it brand new from Keith Craft costing around $11K or so. Parts include R302 block stroked and bored to a 331, canfield heads, Trickflow R-Series Intake both that have slightly been CNC ported, Comp Cams (224-230 dur. & 544-544 lift w/112 LSA...also those numbers are using a 1.6 rocker, mine is running 1.72, so im not sure how to recalculate) canton oil pan, BBK shorty headers, Flowmaster 2 ch. Anyways the original owner was running a turbo and w/ 6lbs of boost it was putting out 646 RWHP and w/ 25lbs 9XX to the rear wheels. I guess after about 1500 miles he had the valve stem seals go out on him (he said they were cheap ones from Canfield...??) So next he then sent the whole thing out to Nelson Competition to have the whole thing tore down completely and have every tolerance, gap, endplay, bore thickness documented, etc. then re-assembled using new freeze plugs, fresh paint, balanced new Hellfire file fit rings, all new bearings, etc. Anyways, i got the whole complete engine for $7200 shipped to my door, that included everything from the upper intake to oil pan, distributor, energy suspension motor mounts. Anyways, i will report back on here and let everyone know the results when its all said and done. Thanks everyone for the kind words and compliments. And a big thanks to my bud Hector for putting all the vids together and more importantly helping me out with all the wrenching and installing...and believe me i need all the help i can get!!...the older i get the less patience i have for big projects, any more problems with this thing and im gonna need anger management sessions ...LOL"

 

[03BlownSnake]

you know what the compression ratio is on it currently?
And since you said you had .544 lift with the 1.6 rockers.. shouldn't that put you around .555-.560 lift?

very nice! car sounds very mean. where abouts is that red Cobra located? near Norwalk Raceway? Id love to hook up at the track one day next summer.

WOWOWOW.....JUST WOW!!!

I gotta give it to you man. Thats exactly how I want my car to sound one day. Thats just amazing!! :bowdown:

Also, Ive never raced a terminator, but why do folks keep saying that the terminators have this mean top end. They have more TQ than HP usually so how do they pull so good up top?
