592 rwhp

 

Your combo is very close to mine. You have a few more cubes and I have a little more boost. I will guess 560 rwhp and 530 rwtq.

 

It should make

horsepower

 

You guys are being generous. My goal is 500 RWHP. 1 Miilion RWHP is also great too! LOL

 

Any issues with the Mass flo? I have the same set up on our 64 Comet with a 408W but have not run it yet with the Fuel inj.

 

Well, yes. Some of the parts supplied with the kit gave me problems.

Mallory distributor lasted only a few years,
Mallory coil, never worked properly

I did have to spend money a few times for the tune on the dyno. Once with my boosted 331 and this time with the 363. Otherwise, it works great but i think there are more less expensive options these days with EFI

 

That T5 will probably grenade the first time it sees boost.

 

Its a G-Force T-5. Should hold up fine, and has for about 7 years.

 

575

 

Enough to soil yourself.

 

I say the supercharger makes up for drive train loss and adds just a little bit more since it is low boost (8.50).

475 to 500 RWHP.

 

In a perfect world it would calculate out to 737 HP at the flywheel. Air temp of the boosted air would reduce that figure by a 100 or so to start. 1 5/8 headers and TB size can account for losses

 

Plus the power to turn the blower.

 

10hp per lb/min.

 

I made 521 with a slipping clutch with less cubes but bigger heads. Boost was around 9 psi. You should be right above that.

 

Results are in!

503HP
466TQ

I'm pretty happy with the numbers.

With my previous combo (the 331 ported TW heads, with the same boost, made 435RWHP)

So the 363, new cam and AFR's made 68 more RWHP)

Because I had the FWHP and RWHP numbers for the previous 331, I calculated 26% loss along the drivetrain and the accessories. 585 FW vs. 435 RW

Whoever guessed 500HP was darn close.

SWEET!! Since I have been messing with my 65 and playing on the dyno just a bit I have realized the numbers always seem to be lower than what we hope for. Don't know why that is. However, 503 RWHP is pretty darn nice!!!

Congrats on meeting your goal.

 

Here's the dyno image. The difference in the two pulls was a restrictive air inlet to the supercharger.

 

So using the previous parasitic loss (26%) having the benefit of the FW and RW numbers (from the previous combo), 503HP RWHP should transfer to approx 675 FWHP.

 

Curious...what clearance issues did you have underhood?

Did you have to put a cowl hood on?

Phil

 

Here's a pic of the underhood. No clearance issues with the '65 Shelby style hood.

 

I love the gold valve covers, that nice throw back feature. Great numbers on the RWHP!

 

Thx! Wanted to add some nostalgia amongst all the craziness going on under the hood.

Stock '65 covers with spacers.

 

What's it like to drive now compared to before?

 

Don't have it back yet from the tuner. Hopefully this weekend it'll be shipped back. I'll post on the performance.

 

Nice numbers! I think you can turn up the boost a bit with the Dart block. You are getting close to the G-Force max though if you launch hard on sticky tires. My '66 coupe running a 331, also with a Novi 1200 at 8-9 lbs but on a '72 block with Canfield heads put down 483 rwhp thru an Astro A5 tranny. Time for me to mini-tub because the 225/50/16's go up in smoke at part throttle.

 

I think I'll stay with the current boost, but you are right, these blocks can handle quite a bit more HP and boost. I run a 295 tire NT05 which is has a big contact patch. It was pretty useless even at 435 RWHP. I haven't tried a drag radial yet but I'm strictly an autocrosser.

 

Am I seeing a power steering pump there?

What pump is that and if you don't mind asking, what front cover are you using? Stock 5.0?

Phil

 

Hi Phil,

The pump is a KRC pump.

KRC 63201000 Pro Series Aluminum Power Steering Pump w V Belt P | eBay


The front cover (I assume timing chain cover?) is a '65 with aluminum pump. The one where the pump has no back plate.

 

Pretty sure the pump is from KRC, but not 100%. They make really good pumps, have one on mine as do a lot of heavier use street/track guys.
