here's my dyno graph of the mods in sig...it's a 98 with 100k miles on it...fyi

 

what do ya'll think

 

thats pretty good. do you have a underdrive pulley.

 

Nice numbers I dyno'd mine today and wasn't as happy

 

no underdrive pulley no ported throttle body...the intake ports on the heads have had work done to them but i don't know how well they were worked on...obviously not very well since i'm not at 400+rwhp

 

im seeing a lot of different results with this cam...most people are dynoing really low.... in your case its one of the better ive seen...

 

yeah i don't know why this cam is bought so much...the f-13 from futral is usually a 400-415 rwhp CAM ONLY cam...you'd have to have heads with the tsp231 to get those numbers...and they are basically the same size...plus futral's low-end is far superior to this cam as well...

 

nice numbers!

 

not bad numbers at all.. i think everyone always compares numbers for the fms cams. those cams are definitely badass

 

a ported TB and UD pulley prolly get u over the 400rwhp mark!
and yes FMS cams do kick ***, just hope my F14 makes it to 400rw cam only

 

For comparison's sake (they look very similar), here's my old stock-head/ 231/237 graph (with a ported TB and UD pulley, thru a 9" with 4.11's).......

 

This cam likes to breathe.

 

i guess i need to get me a ported tb and a pulley...i'm about to seafoam the engine next oil change...i went looking today and couldn't find any...umm i think there is a lot of stuff in there...for one it has 100k miles on the engine...last week the car was running super rich...umm like 3months and the spark plugs were toast rich...so i'd say there is a lot of carbon up in there...

southfl.02.ss - my heads have been worked on somewhat...i've seen the intake ports...i guess they aren't that good...haha...i might redyno it after everything is done...i just don't feel like driving 100 miles to tampa to do it...

 

What is seafoam?

 

top end cleaner

 

Those #'s are pretty good.

 

I dynoed 382 rwhp and 351 rwtq SAE on mine... with the mods in my sig (minus the LSX intake, which I just added). Powerband is really flat, so that was nice to see. Wasn't disappointed considering I'm dynoing through a 12 bolt with 4.11 gears, a denny's nitrous ready driveshaft, and heavier 17" wheels instead of the stock 16".

The numbers were 401 rwhp and 370 rwtq uncorrected. Before the cam I dynoed 336 rwhp and 337 rwtq, so it gained 46 rwhp and 14 rwtq. The only things added between dynos was the cam, the driveshaft and the wheels (both hurt dyno numbers a little).

 

well i guess i'll add a few more things...i have zr1 replicas with 315's on the back, also a spec stg2 clutch that is somewhat going downhill...and i just recently had a few problems with the engine (running supper rich) so i'll sea foam it, get a tb and pulley and have it retuned.. i'm sure i'll break 400rwhp
