What did you do change on the car on the 320 rwhp/341 rwtq. pull? Did you pull the belt off or something? You should be trapping higher with 320 rwhp...at least 108. I don't think we are getting the full story.
Pulled nothing!
I posted a link..........
Again I have not went to track with DR with this setup. I am sure I can run High12s. I think my A/F low I want 12 at WOT 14 on crusing.........
I know on the DYNO day..... I threw little flame out; when let off the gas padel
BTW temp was 104 with 90% humid

What correction factor was used?

The only reason I asked if u dropped the belt is because you gained 11 rwhp and and 12 lb. ft. on that pull. Again, you won't gain much from a tune.

I got my air damn from RK sport cost around $40 I think but it should come with Body kit if you get one. It came with my Rk sport - mine wears out fast though because the car is lowered

Mir, is the higher dyno a difference between stock and 1.6 rockers? My dyno numbers are nearly identical to yours throughout the power range on the lower 2 pulls.

I do agree with Beast tho, the numbers on 1995Red are pretty low. My car with LTs, CAI and true duals made 300 rwhp and 337 torque. Mine had more hp and tq across the board until 5400 rpms. Right now I don't think its worth sacrificing the idle quality and sleeperness of my car for only a 25 - 30 hp gain in a 500 rpm range. Would it be faster, probably, but not by most drivers. I know I pulled an LS1 car that dyno'd about 325, but I had a LOT more torque until 4500 rpms.

On this, I would go so far as to say maybe the cam is retarded. Was the cam degreed before install or just lined up dot to dot. I think this a main reason why the numbers are so different from one car to the next. I just doubt there is that much difference in the castings. Nighttrain said LT1 heads flow 215 on his bench, I had a spare set I had here flow tested, and they did 213, so I'd say they are close.

Where could the extra power be? I have a cc305 on the shelf but I don't think I'm gonna put it in if I only pick up 25 hp. I want 50 from a cam.

those are good numbers

I made mine with stock heads and I have a A4
A friend of mine has a m6 with a decent port job with the hot cam and made 370

i guess after seeing a bunch of dynos from the hotcam id say my car is right on the money. im sure there are a few cars out there that just push more horses to begin with. like i said im happy where i am right now with stock untouched heads.

Where could the extra power be? I have a cc305 on the shelf but I don't think I'm gonna put it in if I only pick up 25 hp. I want 50 from a cam.
extra power? i dont think there is any extra horses anywhere!! the shop had a scan tool on the car during the dyno and said everything looked perfect. how do you figure i only picked up 25hp from the cam?? only 2 major mods cam and headers. so basically gained about 80-90hp over stock between the two. seems most in the 360hp+ range have had head work. oh well!! hey dont get me wrong id love to be pushing around 360hp as the cars sits now! but i think 330 is respectable.

I think there may be a confusion some of the people are reading into horspower... Flywheel or Rear Wheel. To me the numbers look good for rwhp. 80-90 hp is for the flywheel hp I'd imagine.

Not trying to diss your car, I'm simply saying that I think there SHOULD be some more power there. My car with only LT and CAI did 300/336 SAE. So, esentially you lost torque and gained about 25 hp, but didn't even gain the hp across the board. It made less across the board, and only overtook mine above 5000 rpms. Most people also say that the hotcam doesn't peak very high and yours carried out to almost 6000. Also, I would EXPECT a gain like that by simply adding a cam with more lift and duration, but you also have 1.6 rockers, which gives it even more lift.

I am going to do 1.7 rrs soon. I was going to do 1.6s but with everyone talking about 1.7s now, and people thinking the results aren't real, now would be a good time for me to prove it or not. I think I can pickup about 15 rwhp peak, and should see gains across the board.

The main thing is, if you are happy. If so, then ignore everything else. Ignorance is bliss, and if a cam swap nets you that, and thats fine with you, then no problem. I can't see spending roughly $500 for a hotcam kit and only getting 25 hp. Thats me tho.

hey i dont think you are dissing my car at all. but i dont think you realize that you dont see too many of our cars that dyno over 300RWHP with only intake and headers! thats awesome that you managed, but i dont think the magority of us can! you should def. do the 1.7 swap, i was thinking about it, but would like to see a little more proof that it actually is worth the $300 it will end up costing!

i still dont see how you are saying i only gained 25hp from the cam?! like i said stock our cars dyno around 240RWHP.... now im at 330!! that means almost 90hp we gained between headers/cam!!! you say its not worth the money, but yet we spend about $600 for headers and that looks like it gained you the same amount of hp.

Dang, look at all the hating going on! This reminds me of when the first 400 rwhp heads/cam cars were showing up. Everyone said, "Not possible, BS, its a 383, blah blah blah." I think the hotcam is a poo cam and you need more lift and duration, even with stock heads. I believe Hussain's numbers and I think I can match or beat them with 1.7 rrs. Might have to do it a bit sooner than I planned.
