GURU'S:How much Rear Wheel Horse Power

[dstanggt50]

I would say it depends on the heads, how well they have been ported. I dyno'd with gt-40 intake, full lengths, off road, cat back, ported & polished heads, 1.6 rr's, pulleys, pro m that was giving bad driveability issues, 24lb inj, with exh leak 260rwhp (acutally 259.7, but wanted to round to make myself feel better), I think around 270-290, maybe 300 on tune, and like I said, how well the heads are ported. (factor less if your running nitrous tune)
Also, it was a 248c dynojet, so if you get it dyno'd on a mustang dyno, would be less.

Just my opinion.

I turn my timing down to 10 degrees when spraying. My plugs are gapped at .035. Still trying to figure out whats the best plug to run with my setup. Part/Plug#????? Suggestions anyone??? I'm running autolite's now.

i run autolite 24's. one step colder plug. and i use a 100 shot.

my buddy has an identical setup; y303's and an E cam along with the other bolt ons and made 304 rwhp on the dyno. The only difference is he has 30 lb injectors but I'm sure the 24's are plenty.

I just checked back and my heads are the y303 also. I think I'm going to take my car and put it on the dyno, just so I'll know the rwhp. Thanks everyone for the input. Its greatly appreciated.

get a stage one timing retard and a window switch for the nitrous. that way you can have peak n/a power untill your nitrous is activated then the timing will retard, so you dont go boom.
Its the best of both worlds.
