Let's play: Guess the rear wheel horsepower

Categories: running race

Question:

Ok folks, I’ll give you the specs, and we’ll see who gets the closest HP as measured at the rear wheels (this coming April) Currently putting the finishing touches on the new motor (for project "C") 10:1 Compression and a Vortec "T" Trim with 8lbs of boost (at an estimate 6,000RPMS)??? Here is what we have so far: 347 CID, Ford Motorsport Sportsman Block, Vortech T Trim Supercharger Kit With Blow off valve (a must),Pro M MAS, BBK 75mm Throttle Body, Trick Flow Upper/Lower Intake, Trick Flow Aluminum Twisted Wedge Heads (O ringed),  Cobra Valve Covers (they make the car go faster, honest),Crane Full Roller Rockers, stud girdle, F303 Camshaft, Ross Pistons, 4030 H Beam Eagle Rods, Forged Crank, Canton road race Oil Pan, Main Stud Girdle, 50# Injectors, Aeromotive Fuel Rails…Will be running a MSD 6BTM Ignition Box with Blaster Coil with a 6,200rpm chip, dial up adjustable timing as well….. Have fun with your desktop dynos……. Yours In Building Fords (among others at times) Bill S.

Vortech T Trim Supercharger Kit With Blow off valve (a must

what does a blow off valve do? See my vehicles at http://www.geocities.com/saleen8927

Response:

If there is overboost, the blowoff valve will open, stopping any damage that could occur…Very similar to a turbo system……Every bit of safety helps, especially with a motor that cost big bucks to Bill S. – Hide quoted text — Show quoted text – Vortech T Trim Supercharger Kit With Blow off valve (a must what does a blow off valve do?

Whoha! That’s a set-up that will raise a few eyebrows at the track fur shure… Will you keep the stock T-5 behind that beast?

Bill if you want to add something that will significantly raise the safety level for a supercharged/turbocharged engine look at this device:   http://www.jandssafeguard.com/safeguard.html   I’ve used one for years and it will control detonation like nothing else on the market.  For the money going into the engine you described, it is a mandatory piece of hardware IMO.  It also acts as a boost retard and is much better than the MSD retard.  When used in conjunction with an MSD 6AL it is the best ignition setup that can be used on a blown motor.  I’ve run as much as 16 psi of boost and the Safeguard was one reason I even attempted it. Once the sensitivity is set properly you can forget it’s there.  It protects you from detonation caused from the occasional bad tank of gas, hot weather etc. – Hide quoted text — Show quoted text – If there is overboost, the blowoff valve will open, stopping any damage that could occur…Very similar to a turbo system……Every bit of safety helps, especially with a motor that cost big bucks to Bill S.

That combo is very similar to the one we put in my friends ‘92 GT.  The engine can be seen here: http://community.webshots.com/album/60172732BoXBQl I’m guessing you’re gonna see around 600rwhp give or take.  My friends has 9.5:1 CR, twisted wedge heads ported and polished to Probes stage 3 specs, he’s got an edelbrock performer rpm intake, his supercharger is an intercooled procharger with blowoff valve also putting out 9lbs of boost.  Should be pretty mean when its done, to say the least.

Hey, I was being a little optimistic ;) .  The desktop dyno showed 740 flywheel HP for my friends motor, and yours looked pretty similar, so I thought it may have been a decent guess, but I know desktop dyno isn’t exactly the most accurate dyno out there.  We shall see!

Response:

well if it doesn’t detonate it’s self to death with 10 to 1 compression, i guess 420 + or – 5% at 6000 rpm.

Response:

A 10:1 engine can be built to run a supercharger quite reliably.  If everything is tuned correctly, and the heads/block is o-ringed, there shouldn’t be any problems as long as the timing is set low enough to run whatever type of gas you put in it as long as it is at least 93 octane. And it should have alot more HP than 420, that motor would probably make close to 350-400 WITHOUT the supercharger.

a desktop dyno isn’t the real world! my guess is still 420 + or – 5% rwhp on pump gas. lowering the timing to avoid detonation will zap the hp right out of it. race gas would allow more timing & hp, but running race gas is not exactly streetable IMO.

Response:

As with my last buildup, I plan to use 92 octane pump gas in the car…..Race fuel (ie; the additives) is aromatic, all of the good stuff evaporates too quickly for any real street use……Got tio be streetable, as I do plan to drive "project C" all around the country Yours In Driving Fords, Bill S. – Hide quoted text — Show quoted text – A 10:1 engine can be built to run a supercharger quite reliably.  If everything is tuned correctly, and the heads/block is o-ringed, there shouldn’t be any problems as long as the timing is set low enough to run whatever type of gas you put in it as long as it is at least 93 octane.
