Dynamometer Results & Comparisons - My dyno numbers

I have an 06 gto m-6 with a 402 stroker , fast 102 ,cam 247/251 624/624 on a 114 , electric water pump , harland sharp rockers also with RPS twin clutch with one piece shaft and 3:91 gears oh and slp under pulley and k&n intake and American racing headers 1-7/8. The car put down 496 rwhp and 438 rwtq what do you guys think of those numbers?

What heads are on the car?

Yeah I forgot about those lol ,trick flow 225's

What dyno?

My car with with a 408, ported 102, 244 248 612 615, tfs 225's, harland sharp rockers, Ram HD clutch, 342 rear end, power bond pulley, Kooks 1 7/8's headers and a stock water pump made 499 and 469 trq. I would say you are a little low but not alot.

I am going to a electric water pump eventually just have had the money yet. There is a thread about 408's and dyno numbers. It is stickied, check it out.

What dyno?

Mine was a dyno jet and if you were on a mustang then that would make a big difference.

How is the drive ability? That is a lot of cam.

It was on a dyno jet, driving around town is great !!!! no issues at all.

Who tuned it? What catback? At first glance the numbers seem a tad low, but there are many variables in a setup like this. My 402 started around 445whp and quickly moved to 511whp with some intake/exhaust tweaking. :) That was with a similar sized cam with LS3 intake/heads.

It was tuned by RPM and the car has Spintech exhaust 2-1/2 inch.

Nice numbers! Those 3.91's in a IRS car are eating up a few hp, I'd ditch the k&n intake.

Yup i agree also, i ordered the Svede intake last night should have it in a week and a half How do you like yours?

What kind of compression? On paper it looks like a nice setup ... but the results do seem low .... My 402 made 508rwhp/497rwt on a DynoJet with 90/90, 1-3/4's & 215's.

I see alot of "lower" torque numbers with the 102/102. Several threads & postings have mentioned they seem to hurt torque. With the improvements over my 402, I expected to see 525+rwhp and torque numbers close to or just over 500 for your setup.

Just reallly going off of what the product said it will do !!! along with me reading about other setups and what other cars are putting down?

I am curious what you were expecting?

I was looking for 520rwhp and 515 rwtq do you think im looking for to much ?

Go put it on another dyno and see what it reads. Maybe that dyno is stingy?

Are the 225's cnc'd or as-cast? What did the heads bench flow (flow #'s provided)? Is the FAST ported? Has the tuner said he can get more out of it or is it "done"?

Could have a little to do with the tune also. Check the tune. Are you running speed density or what? Seems like a strong build so i dnt see why you wouldnt see atleast 505-510 RWHP....

The heads have been milled to 62cc or 59cc not sure but no porting and the fast is right out of the box and throttle body has been ported.

I love it so much , The car pulls so hard on high rpm and reads lower IAT .

I bet you'll gain 10+ rwhp on your setup with Svede intake.

The power looks good for the setup. The intake hurts alot and also the exhaust. I really like the Kooks dual 3" setup and switch the midpipes to 3" instead on the knocked down one's. Cleaning both of those up will show big torque gains.

So how much is the exhaust hurting my numbers and what could i do about the fast 102 to get more out of it?

The FAST is fine. It's the intake piping. We ussually do a custom 4" pipe which helps alot.
For exhaust gain, best test is to dyno it open headers and see.

I agree the intake/exhaust exhaust could be a major restriction. On my 402 (Formula) I gained 20whp by switching from an SLP lid and stock MAF to a 104mm FTP lid and Z06 maf. I picked up another ~45whp or so from going from a 3" y and hooker catback to a TSP true dual setup. The intake/exhaust switch took me from 445whp to 511whp/480wtq! My car also tuned by RPM. The tune is NOT your issue, I can assure you that. :D

I know its not the tune ,I just dont understand with the mods that i have already why i wouldnt get the results that im looking for. when it was just a heads &cam car without the 402 it was making 460 or 470ish then with the 402 went up to high 480's low 490's now with electric water pump,1 7/8 header larger cam i picked up 6rwhp ?

Think of the motor as a simple air pump. Now you've increased the volume of air that the motor displaces, you now need a way to more effectively move air in/out of it. With more displacement comes new bottlenecks in the way. :)

This stuff never ends, heh.

Your airbox/intake tube restriction (not as familiar with the "Goat") and the 2-1/2" exhaust is hurting, but, I think it is something more than the FAST 102 and 1-3/4" headers ... here is my graph. The only difference between the "green" graph and the "blue" graph is the addition of a SDPC 402 short block. This is through a Vengeance ported FAST 90/90 NWTB, CNC'd TFS 215's and 1-3/4" Kooks into a 3" ORY and 3" dual-outlet Flowmaster. You must be pulling in the same or more with your "out of the box" 102.

I believe all of the TFS 225's are cnc'd and the as-cast is the TFS 220 ... someone can correct me here ... so I believe your head flow is fine and more than my TFS 215's.

As cast is the 220 trickflow. Things to consider is how much the trickflow head was milled, what the static compression is, what fuel are you running, what head gaskets were used, was the piston run out of the hole when the short block was put together, what pistons, etc....
ive played with 2.5" catbacks to 3" catbacks on my blown GTO with no noticeable gains. Maybe 2 to 4whp. But that couldve been the day. Hard to say?

Not a firm believer in the svedeOTR intake either, the short runner length and placement of the maf sensor can make a larged cam car are real turd for street manners. With the long intake runner tube of the LPE, powerchamber, etc... the intake place the maf farther upstream from the throttle body alowing a steadier flow of air across the maf. Creating a better running better tuned car.

Plz excuess the grammer in my last post. This is done from my lovely droid!

The car has the 225's I don't know if that matters, wesico pistons callies crank heads were milled 59cc. Don't know what the static pressure is, running 93 octane

-8cc Dish Wesico's?? Any specs on the deck??

this a copy of the dyno i was wrong it put down 503rwhp and 458rwtq.

congrats!

i saw the cam size and i thought it was RPM! Roshan spec'd that cam for me as well but on a 111 lsa for my stock cube 346 :)

btw the dyno does show lower numbers compared to others around

i have a SD tune so not using maf and have the stock intake piping and maf hooked up to an slp lid. i want to take all that out and get a smooth intake pipe directly into the ftp 104mm lid. do you have any suggestions what piping i could use to fit this? i may have read somewhere the 104 lid is 4 1\8 i.d? what is the o.d of the stock tb? going to be a wierd setup
