300 RWHP and over

[90LX306]

Afr 185's, Track heat intake w/spacer, comp xe274 cam, 1.6 rr, 1 3/4 lt's, 75mm maf, 70 mm tb made 309 RWHP and 311RWTQ. Would have made more power w/165's but im planning on a blower in the near future soo it should respond well with what i have. This is a stock block, eagle i beam rods, je/srp pistons, stock crank. With a TFS stg 1 cam the car made 295 rwhp, that cam was emissions legal.

 

[Chris6050]

Stock shortblock, 48k miles.
Dyno'd at 287 and then added an electric fan and capacitive discharge ignition. Didn't get it redyno'd but those two changes really woke up the car so I believe I am right at 300 RWHP.

Wow those number seem really good for using Powerheads. Thats sweet.

 

[Demented4.6]

my buddy ( 93vertlx) put down 297 rwhp with same combo as me but street heat intake and TFS stage 1 cam and 3.73s.. my car pulls on him slightly ( still enough LOL ) so id say we are both around 300-315

gives me some ideas....thanks.

Well I am making 331 RWHP with my setup and with no power adders.

Here is my setup:

306
GT40P Heads Ported and Polished with 1.90 x 1.60 Valves
Crane .550 lift Spring Kit
1.7 Roller Rockers
Professional Products Typhoon Intake Manifold Ported and Polished
Mac Cold Air Induction
Anderson Ford Motor Sports N-41 Custom Camshaft
70mm TB
80mm MAS
30lb Injectors
Mac Shorty Headers, Mac Prochamber and Mac Cat back Exhaust
MSD 6AL Ignition with MSD Billet Distributer
MSD 9mm Racing Spark Plug Wires
Iridium Plugs
Mac Underdrive Pullies
Art Carr Street Terminator Transmission with a 3000 Stall converter
FRPP 3:73 rear gears with 31 spline axles, an Eaton 8.8 Differential
Custom Burned Superchips computer chip
255LPH Fuel Pump
Adj. Fuel regulator
Set the timing to 16 degrees advance and the fuel to 37 PSI
Eibach Drag 90/10 shocks, FRPP Progressive rate springs
Eibach upper and lower control arms
Sub Frame connectors
QA1 Tubular K Member
Fiberglass hood with 1.5in cowl
Race Weight with driver is 3120
Price to build about 10K

I average about 30 miles a day driving, I also get 18-20 MPG on the highway and 12-15 MPG in the city. I also have run a best 12.086 @ 113.21 MPH with this setup and I still have power everything including A/C.

Not sure i've ever seen or heard of a car with p's dynoing over 300rwhp. In fact the most i've read about so far is less than 280 regardless of the port job. Is there something you are not telling us about the motor considering that's about 50 more than i've ever seen, and about 75 more than a stock p headed combo.

Not calling you a liar, just seeing how the hell you managed to squeeze that much power out of them. Because they are a very obtainable head for most members here on a budget. And when budget permits they can be ported.

 

[stangman 50]

85 gt lover there is about 10 more i left out, suspension, guages, nitrous kit,interior, rims. im pretty much done for the most part i hope i just want to put in all new break lines and pads and rotors and then a nice paint job..

 

[GATOR98GT]

Well I am not at 300 My best dynoe was 291hp with the mods in my sig

I avg around 284-287 with the 291 being somewhat of a anomoly

Also that is of course without the nitrous

P heads actually can work quite well depending on the combination. I am friends with Tremec Street Warrior Champion "Jeremey Martorella" and personally saw 430 RWHP with a set of P's in a 310 cubic inch motor.

 

[cjman15]

i make 250... woo-hoo... i need some H/C/I

 

[Demented4.6]

No i don't have any dyno #'s for my car. i was just going off my buddies car compared to mine. i pull on him throughout the rpms so i figure i am putting down slightly higher numbers than him. Hopefully if i get this Tweecer soon i'll get to the dyno and see what i can get out of her.

Well my heads are not only ported and polished, but I am also running larger valves and a ported and polished intake manifold, also the N41 Camshaft is simply incredible it was what put me over 300HP mark...

By the way the GT40P heads added almost 40 HP after I bolted them on.

 

[WantaGT]

hey 91Stang, your combo, with the aod and all looks like the combo i want to put together. on a budget lol, but what are you et's?

 

[91StangLX]

I run 12.086 @ 113 MPH with 1.7 60 foot times. I am selling this car for 5000.00 on ebay, so if you know anyone interested let me know. Thinking of going modular 4.6

 

[Ekliptix]

That car made 291 rwhp in MMFF this month 340 was flywheel.

Was that on a MD or a Dynojet?

My holley package only made 247whp at 5100rpm on a MD. It's floating past 5150rpm though, so new valve springs should bring it to around 280whp I hope.

 

[beaver2489]

I should make around 300rwhp with my setup...once I get my mass air coversion installed anyway. I'm sure I'd make 300rwhp if I had a more radical cam, but I like what I have for a daily driver. Feels strong and sounds like true american muscle

 

[FiveO]

the trick flow h/c/i package is only 2,050 bucks in summit. and they claim about 350 hp with a new maf and tb. thats cheaper then the old system max 2 setup.

Thats flywheel they're talking about remember......although its still around 305-310 rwhp which is pretty damn good.

 

[maverick0716]

Are you talking flywheel or rear wheel? Also, have you had your car dynoed? If you have, you're making some damn good power for the mods you have!
