Removed l92's for t.f.s 235's + and went to track. My old set up was 402ci 11.1:0 comp,242 250 cam,ported l92's,vic jr. Car is a ws.6 trans am,m6,asp pulley,kooks 1 7/8,off roads,3'' cutout,12 bolt w/4.11's,90mm th body,85mm mass air, 3480lbs with out me in it.
NEW-still 402ci,11.6:1 compression,24x/25x cam,out of the box tfs 235's,out of the box fast 102mm. All boltons are the same..
Both dynoed 530hp but the tfs heads made 12lbs more tq through the entire power band producing 12 and even 15 more hp in some spots under the curve where they both meet at a 530hp peak. This is a mustang dyno. I will try to post a graph of an over lay in the dyno section as soon as i can.
Old
1.44 60
7.03 1/8
101.33 1/8mph
10.863
127.66 mph
New
1.50 60
6.921 1/8
102.01 1/8mph
10.631
130.08mph
I was hoping for lil better but i think my slicks are shot. With the same low 1.4 60's the car could of went 10.5 at near 131mph easy and it will.......
My wife was to go and video but she backed out on me..
I hit the rev limiter the first run and went 10.86 @128.99 on a shitty 1.55 60 foot. I had a hard time keeping the shift points for both runs. I have a shift light,but think a real tach will put me on the money since i have no clue as to when the light is gunna come on. Also,i think i need new slicks,i was told i was spinning some off the line when i used to dead hook to a 1.42 to 1.44 60 foot. I seemed to cross at 6,500 rpm's or so in 4th gear and may try a 27'' slick for next season to give me a lil more side wall. I feel the car has another tenth in it with better driving and new tires.
Also,i'm gunna have the intake ported,go to a 100mm massair and 100mm th-body and hope for a 10.4 1/4mi car that has power windows,locks,leather seats,heat and full interior like i do. Thanks,mike c.

I actually dont see a huge difference. there are enough variables in the diferent setups to make the 3mph difference. comp, intake, cam.....
NO DISRESPECT to the TFS heads at all, I am just REALLY impressed with the performance of ported oem truck heads!

you up'd the compression and upgraded the intake, also who ported the L92's? to me you cant compare a budget head/intake to a high dollar intake and head set up.
you only gained 2 tenths, you should have upgraded your heads to mast or tfs L92's and a fast 102 before going back to cathedral

On these runs i was hitting the rev limiter in first gear,i just tepped it on the best run and kept in it. The weather was low 60 deg and thats the only time i go to the track. beginning of year in the 60deg and in fall when it hits again. My last set up over this one i was told after the tune i have a restriction in my induction system now. going to larger mass and th-body will gain more. also my exhaust is arestriction. last set up opening the cutout gained me 16hp,now opening it gained me 30hp.. Where my old set up was dialed in and maxed out,this set up is not....and in the end will gain me more over the last. The cams are both simular size with the l92 having a good bit more lift to it..

Nice gains. Again you can't compare the 2. The 102 should pick up torque and with the Vic Jr you really need to rev the engine.
If you put a soild roller and spun the engine with the Vic Jr you would pick up over the Trick Flows and 102.

who's trying to compare the two set ups? It's two different sets of heads and intakes. all i'm showing is a gain or loss from a swap. This new set up does have more restrictions on the intake and exhause over the old and when addressed should shine alot more. But this is not a apples to apples compare. I do feel the new set up has more ability to go faster when all is put togeather.
1lejohn- The vic jr on the l92 heads picked up 19hp over the fast 102mm and l76 intake. it did lose a good bit of tq way low but picked up where it was only down 8tq on the topend. With this set up i made the same hp on the topend and gained from start to stop in all areas. I will post a graph when i can get to my friends house to do it.
The trick flow set up is not stomping the l92 set up so bad everyone should run out a buy them. I was wanting to improve the set up and had tried different cams and intakes on the l92 and was just done. Now it's time to see what the trick flow set up can do when it's dialed in.
