This thread and my comments concerns the FRPP blower, not centrifugals or turbos.

Base FRPP blower is 525 crank HP and once all is said and done you will have $8500 in it dealer installed and it will add about 100 pounds to the car.

Normally aspirated bolt-ons are going to get you to 500 crank HP and make it just as fast as the blown car for less than half the cost.

Less stress since you won't be pushing any boost.

bolt ons getting you to 500 crank hp is a sretch as of right now. 475 sure

7 psi @ 190F vs 9 psi @ 110F is a huge difference in air volume. Where as 7 psi @ 100F is not that large of a drop.
Whipple supposedly saw 550 rwhp on 7 psi with the IC and a non-emissions tune during development.

I have a thread about this.
I think you'd see 500 crank with what's out right now.

CAI
Headers
Full race (catless) exhaust
Forged pistons with 11.5 compression ratio
Tune @ 93 Octane.

I think those 5 things would get you 500 hp (or at least close).
If not they it surely would on race gas.
And cams will probably be hitting the market in the next month, with them and the ability to spin to 7500 rpms (like the Boss) and 500 crank is easily attainable.

Want to stay street legal with high flow cats and I think you'd be at the 475-480 crank you are suggesting on pump 93

I've never owned a supercharged car but have owned 8-10 turbocharged cars.
Does a supercharger, intercooler and supporting plumbing really add 100 lbs?
I think that's a bit excessive. It's probably more in the 50-60 lbs range, unless superchargers are quite a bit heavier than turbos (which they look like they are somewhat heavier).

Go pick up a FRPP 2300 supercharger, the aluminum manifold, the intercooler core, the intercooler pump, the heat exchanger and all the associated plumbing that goes with it and see how much you think it weighs.

Could very well be quite a bit more than 100 pounds.

The stock plastic intake that it fits in place of weighs nothing in comparison.

Shaun's car is already at 430RWHP with CAI, Tune and mufflers.....Just say'in....That is pretty close to 500 without an exhaust system...

Fazm

those (pistons) are not bolt ons, he said bolt ons


i agree thats close, but i dont do the backwards rwhp to crank math as generously as some people do. when i was 454rwhp i said i was close to 500hp at the crank.

Mustang powertrain should be around 12% in that horsepower range so about 440 rwhp should be their.

That said Whipple/FRPP advertised numbers are usually from rwhp / 0.85 so that would be 530 rwhp from the 9psi IC version with included tune (Usually lean with low timing for emissions).

Lower 7.0 psi version would be closer to 446 rwhp.

What non-intercooled ???

Even the 525 HP base kit is intercooled, the 5.0 base kit isn't like the base 4.6 400 HP kit.

Wow, as I stated, I've never had a supercharged car so I'm not aware of it's weight, but that is heavy to be on top of the engine. Maybe turbo kits are the way to go.


He could have dyno readings that said he has 470 rwhp, but the fact of the matter is, unless the dyno is calibrated correctly and reading properly, it means nothing. Unless running race gas or meth, you aint going to get 430 rwhp (or 485 crank) from an intake, exhaust and tune on the 5.0
That's just an over inflated dyno. All you have to do is look at the baseline dyno to know that for sure. If stock the dyno reads more than 370-375 rwhp, the dyno is not calibrated correctly and is a marketing ploy by the shop so they can have dyno glory and get lots of customers to go there to dyno their cars and brag about how much power their cars have. You are not getting 60 rwhp gains on the 5.0 with intake, exhaust and tune only. Unless that is a full race (catless) exhaust with headers and a race gas map, then maybe its possible to be close.

Sorry brain fade.

I wouldnt be absolutely sure the 624 bhp kit wont make 10's.

Brice has went 11.3 in a 4.6 with no other engine mods except a FRPP 500 bhp (Not the 550 bhp) Blower Kit and VMP Tune. Even has the stock Mufflers and Converters. He did have a Steeda Suspension (Handling Type) and Stickies on Wide Street Wheels (No Fats ands Skinnies).

CooBra07

I ran an 11.53 @ 120 mph on my 4000 lbs Shelby GT500....on 512 rwhp and 505 rwtq. So I think 10's are very possible with the 624 kit.

As to the weight concerns, an article on Autoguide.com states that Ford Racing claims the kits to add 47 lbs.

Driver72

Now that seems about what I'd expect and stated above. But I don't really know.

todd03blown

Hey buddy...believe what you want...It was done at Livernois and was DONE CORRECTLY....There are theads all over the place on this.....guess his #'s speak more than your conjecture...

Adam

You aren't comprehending what he is saying. The test could have been done "correctly", but if the dyno isn't calibrated properly the numbers are bogus. Most would agree you shouldn't compare dyno numbers anyways, since there are too many factors.

Driver72

Once again Adam, you are on tee.

I've dynoed many cars and on many different dynos and facilities, I'm more than familiar with inaccurate dynos.
But if Todd wants to believe a stock SAE certified 416 hp 5.0 liter engine that's rated by Ford at 412 hp is putting out 445 crank hp to give Shawn 390 rwhp, so be it. But Todd is either very inexperienced in dynos or he's gullible, it's funny he wants to believe an independent tuner dyno shop over the SAE and the makers of the engines themselves.
Todd may even believe another guy's dyno that stated he made 402 rwhp stock. That would be good for over 455+ crank hp, but he would get laughed at to suggest the dyno reads properly but his car is just an exceptionally strong one that's got an additional 40 hp over what the SAE engineers certified the engines as having.

Todd hasn't quite figured out some tuner shops LOVE to calibrate their dynos to read high. Doing so, brings in the dyno glory guys who WANT to brag about how much power their cars make. It's marketing and good for business.
If that dyno came back and SAID his car had 340 rwhp, do you think Shawn would post that up on forums? Do you think the dyno shop would market that on forums? And do you think a bunch of people would want to go their and then dyno their cars?
NO, NO, and NO.

Some shops WANT to calibrate their dynos to intentionally read high. It's good for THEIR business. But it doesn't make them accurate in the slightest.
