New dyno numbers: 04Z, pat g cam, LT, FAST 90/90
Just got the car dynoed after putting a ported FAST 90/90 on...new numbers are 433rwhp and 402rwtq. This is up from 419/391 without the FAST.
Mod list:
Pat G Cam (227/231 .614/.617 112+2), ported fast 90 by tony mamo/90mm tb ported by Vmax/pete I, ARH 1 7/8, vararam, pulley, Ford 30#
Numbers are ok, I think my cam is holding back about 10rwhp. I dont think its optimized for the stock heads due to the huge lift. (227/231 .614/.617 112+2).
Edit for dyno pics: The circle is what Im talking about...I think thats where my power goes missing. O and Iphone pics dumdumdum
Mods: cam, lt, pulley, vararam, pre fast
Post FAST 90/90 (ignore the 390tq, the dyno didnt pick it up. Numbers were 432/402 all three times

sounds good man. i got a 224/230 with like a .605 or sumthing like that( dont have the card in front of me at this moment).. but i was at 428hp, but i had bad fuel and it was pickin up knock, so he backed off timing, and i got 420hp, and 404ish. ( dont even remember lol) but yeah. im plannin the fast setup and some good heads.. can you feel the difference with the fast 90 90?
and have you been to the track yet? since we have a similar setup ( curious about numbers)... .. and what tire you runnin

I dont really know whats holding the power down, Im going to try to scan the dyno sheet, you can clearly see where there seems to be missing power with the way the curve looks at about 5k.
I can do heads, but I think I might just keep it as it is till I can boost it, then get a blower cam. WI would be happy with 470rwhp with the ability to drive it everyday if needed, however. If keeping it na I will talk to pat g and pick my heads first then design a cam around those heads to maximize the power...I think thats one of the reasons why more people dont hit the high 480-500rwhp is b/c they pick a cam first then throw heads on when it should be reversed, pick the heads then a cam thats perfect for them
I ran a 12.3 at 120 with a 2.25 60ft (stock supercars at 40psi...a pure 100% street setup) and a DA of 1300 or so with the above mods, but the tune was a bit off. Im hoping for low 11s with tire/1.7 60ft.
The car rips on the street, I think if I had a different intake setup like a callaway or honker, I would pick up 5-8rwhp, as the vararam doesnt do squat on a dyno. Despite the lower numbers, it is a very fast car that would give any 500rwhp cobra a whoopin

Car was tuned on the street too because I didnt have access to a dyno. I do plan on getting it to a dyno with my laptop on hpt soon to see if I can mess with fueling/spark to see if there are more dyno numbers. I then plan on logging/tuning at the track to see if I can get some better times.
My only concern is that with the vararam (since it is just 2 big scoops basically), the airflow is soo much different on the street than on a dyno, that fueling may be off when driving around.

Well cost to gain was a little low on the intake but you have room to grow if you ever upgrade your heads (which aren't that bad to begin with). Otherwise, I'd say you're making fantastic power for cam only. Ask yourself this: what's torque like across the board? If it's flat (which it probably is), you're in great shape.

Cars need to be tuned for how they drive on the street. Not how they drive on the dyno.
Your #'s are respectable. There's probably more to be had with a different cam but it's not a lot. 10rwhp at most.

Just throw a good set of heads on there and be done. AFR 205's or even TFS 215's if you don't mind getting different rockers. I say AFR 205's milled to 59cc to raise compression, then watch your numbers go near the 500 rwhp mark.
How's the drivability ?? If its perfect then as Damian said why mess it up for a few more hp? My 402 doesn't have massive PEAK numbes, but it does have more power under the curve then just about any other N/A 402 I've seen so far. Very good manners, and only gets wild when you go WOT.

The car is great driving around on the street, I do have a little cold tuning to do as it will usually die if I come to a stop when its not fully warm (RAF is too low I think) but once warm it drives and runs great.
Damian, your right. I know the car is faster than a 430rwhp, if that makes sense.
Honestly, the curve isnt that pretty. Ill see if I can get it scanned today so I can post it up. Ive seen more power/better graphs from smaller cams (ie Pat G 224/230) Pat specd me this cam to be a little more wild/make some more power than his 224/230 since my lobes are LSLs

Stock 243 heads correct? Making 430rwhp is more HP than some of these guys make with milled PRC heads and TSP cams. Thats nothing to complain about. That cam is not a max effort cam by any means. You cant compare your dyno numbers to someone else's car unless it was done on the same dyno the same day. What you can compare on dynos is how much hp your car baselined at, and than how much hp you gained for your mods. You can't have your cake and eat it too!

If the dip was not there with the old intake, but was there with the new intake, I feel that it's most likely tune/fuel related and not valvetrain related. Did you log the dyno runs to see what your spark/fuel/and TPS were doing at that rpm? I've seen funny things with Corvettes on dynos where traction control will creep in even when you have the car in competition mode. The throttle was actually closing around peak torque. Going into the traction control section and maxing out the torque values typically fixed this. Not sure if that's what's going on with yours, but it's not cam related. It's tune related.
