445

93lx · Apr 7, 2006

I had recently dynoed my sbf 445 and i thought i would share the results.

4.100 crank
6.250 rod
4.155 bore
Victor 7721 heads
15 to 1 compression
nasty solid roller set up for NOS
Super Victor
1450 cfm carb.
Moroso Vacume pump.

Considering that i blew the head gasket on the 8th pull and continued on, motor made 799 hp @ 7100 rpm & 633 tq. & 6100 rpm. I know the motor has more, but the motor was not sealing on the outside due to oil leaks and the vacume pump would not pull as much vacume. Also, that's with a Nos cam , which i made N/A pulls on the dyno.

Do you have any specs on the cam or flow numbers on the head. Ive got something similar and I'm just wondering how close I am to your numbers. Wont have a chance to run at the strip for a few months yet.

Heads flowed 369 / 260 2.18 / 1.60 valves cam is a solid roller 844 / 846 282 / 291 duration

That is one hell of a cam. Scary !

Whats it going into? That sounds like a bitchin motor.

93lx · Apr 7, 2006

It went into the motor that i listed above. Already dynoed.

I think he means what is the motor going in, lol

93lx · Apr 7, 2006

My bad, lol, it's going in a 93 hatchback. Probably around 3100 lbs.

Is the car gonna handle that kinda power and what you think it will make on the bottle ??

93lx · Apr 7, 2006

I figure the motor will react crazy to the juice being that it has a nos cam. I'm say a 200 shot will gained 250 hp.

tonys10sec306 · Apr 7, 2006

You made some hp number

93lx · Apr 8, 2006

I'm happy with it. I wish the torque was a tab more, but i really don't know whow much torque those victor race motors generally make.

on the engine masters mag i have they tested a nitrous cam and it made almost an immeasurable amount more HP than a standard cam. (similar profiles) just an FYI

With that much compression and camshaft, he NEEDS a nitrous cam!! Otherwise the heat would kill it...what caused the head gasket to let go?

93lx · May 29, 2006

I used the fel pro 1046 gasket and it appearred that the gasket leaked out on the top side og the gasket, near the edge. I don't know what caused it, but i recently put a set of the fel pro mls gaskets on there.

TorinoStyle2 · May 29, 2006

Those MLS gaskets are even worse!!
Do it right, get the block and heads cut for 0-ring's and reciever grooves, and run a dead soft copper gasket.
If its blowing gaskets on just the motor pulls, imagine whats gonna happen when you push that button.
The 0-ring and copper gasket deal will handle anything you can throw at it.

93lx · May 29, 2006

I actually had the copper titan gasket onhtere at first, but notice that the bore of the gasket was hanging over the cylinder a hair. both were 4.155 bore. I have not crank the motor yet with the mls, but if they don't work, i will definitely go to o-ring. That crossed my mind a hundred times before this,

15-1 compression and no o-rings maybe?

What block are you using?

93lx · Jun 8, 2006

Sportsman 9.5 dart

Just a little fyi (at least it happened to me). I used to run copper head gaskets with 0 ringed block. Still wanted to poop past. (and wasn't even running juice back then).

And trust me, it had GREAT machine work performed............
