My combo:

93 RX-7 (FD)
2004 GTO LS1
MS4 cam, and PRC dual spring kit
LS7 lifters
PRC Stg. 2.5 5.3l CNC ported heads. Milled down to 59cc chambers
60 lb/hr injectors
LS6 manifold
Shaner S3 ported and filled stock TB
Dual 3.5" ramhorn style intake system.
1 7/8" long tube ceramic coated headers
True dual 3" with X-pipe, and no cats.
3.55 gears

The dyno was done on dynapacks, in 4th gear.

Peak numbers:
487 hp
435 ft-lbs

 

Damn, strong as hell for no 90/90. Is the drivetrain in that car very heavy? I notice it's not a dynojet. How does this dyno compare to other dynojets SAE?

 

What do you mean heavy?

The operator said that its typically 3-5% lower than a dynojet on cars he's put on both.

 

very strong numbers congrats!!

i think he means like w/ us when we put dana 60s and a steel DS that youll lose some power cause the drivetrain is heavy compared to a stock rear and DS.

any track times?

Well its got a T56 trans, aluminum flywheel, spec 3+, 3.5" aluminum DS, 04 Cobra 8.8 diff, DSS stage 5 axles. I suppose its "light" lol.

No track times on this setup. My car is primarily a road course car. I've got 670 lb/in springs on teh front, and 560 lb/in on the rear. Traction straight line isn't great.

I did get a cam only time last year of 11.8 @ 119. I have to baby the shifts or it will shock the tire and light the tires up because of the stiff springs.

 

Added my EFI Live tune file for those that would like to see.

 

road course aye?? you run at mid ohio?

i love racing there!

dont know how far you travel or what not but i race all over the mid west and east coast in a twin engine kart in the WKA

I can promise you that if your car made that number theres no way that dyno reads lower than a dynojet.

 

Just telling you what the shop owner told me based upon cars that he's had on both. Hopefully we'll find out soon enough. The shop owner is talking to another local shop with a dynojet to see if I can get on it for free so the two shop owners know how the two compare number wise.

 

are those rear wheel numbers???

 

I suppose you'd call them axle numbers, since on a dynopack it bolts to your hubs.

 

wow nice numbers. specially without a fast 90/92.

im assuming you had to flycut with that cam and those heads?

btw, beautiful car. I love the FD's

 

Great numbers, I like the other guys are a little tentative to go all in considering you don't have a great set of heads (afr 205's / tfs 215's), and only have an ls6 intake. Either way, congrats, and as light as that car is she should scream !!!!

I'd love to see her on an independent DJ. Again not doubting you, but I am doubting the dyna pak (???) dynamics dyno. DJ or Mustang around here.

 

The classic line ^^^^^^^

Those numbers are really good but Put it on a dynojet and Ill gauruntee that that your not going to see 510rwhp.

 

Nice numbers.I like how some jump on the bandwagon about how your numbers will not be this amount on annother dyno,or the fact that tsp heads dont produce.My cheap headed Ms3 cam runs 10.40 at 126 with ONLY-----433 hp and 36x torque,oh ya Mustang Dyno.Nice numbers either way enjoy your new combo!!

 

Your running 10.4@126 because your a stripped down to 3150! put your setup in a a full weight street car like most people have on this site and you wont be running 10.4@126 with your cheap headed, MS3 setup.

 

Ms3 cam,PRC 5.3 heads,Fast 90/90,Yank PT4400,Strange 12 bolt 411 spool,11/23/08, 10.4370-126.37mph-1.3668 60ft.NEG-500ft. 433HP-373 TQ-Mustang Dyno,Straightline 3150 LBS, Chrs1313 custom RAM AIR

I hate point out the obvious, but your car ^^^
is set up for the track, 4400 stall, 411 gears , abd at 3150 lbs !!!! You had better run 10 something with that setup or something is wrong.

Here's a challange since you have a mainly track car, drive your car to Texas and back several times. I'd like to see how your car likes sustained 3500 rpms on the highway.

Power on the dyno doesn't mean **** if you can't put it to the ground. You definately can, very impressive to say the least, but you can't disqualify someone that runs high 11's with the same power if he can't get it down the track as well. It all in the setup.

Dyno numbers are only a prediction of what she's going to do on the street or track. The suspension, stall, gearing, and last but not least the driver mod ulitimately determines what your car does.

I'd love to experience a run down the track in your car. Your car is definately setup to launch and go !!!

Not trying to start a pissing match, just pointing out the obvious, partially because my old 346 had 123.6 mph trap with 490 rwhp 445 rwtq, but because of my 2.11 60's everyone thought the numbers were inflated. Burying the speedo was all the proof I needed that she was making great power. Can't wait to run my new 402, hopefully I can launch better this year.

 

You said what I was thinking, but I was trying to be nice. Got give him credit though, that 4.11 gear is really helping him out on the track, and he has the times to prove it. Good job !!

 

Nice setup, congrats!

 

there was a car no to long ago that made almost the same numbers without the heads being milled and ms3 instead of the ms4. it was a car that was tuned and dyno'd at cms... datzneet or something i'm not 100% sure on the guys name...
