The car is a 6 speed, 3.42 C5 vet. GTP stage 2 heads with 1 3/4" primaries and !CAT!. My set up breaths well. Without replacing gears, I want more low end TQ. My current set up takes until 4200 rpms to get to 300 ft-lbs of TQ.

I want something that is more fun from stop light to stop light, that you can take to the track and run 12.0s on steet tires . I want a cam that is somewhere between a 405 Z-06 cam and the tr224. I also want to limit rpms to 6300 to 6500 rpms. I have 987 duals and a speed inc built 346 motor. I dont want lift above .570/XE

Cams of interest:
220/220 114XE
221/221 114XE
222/222 115-116XE

400 HP and 390 TQ are what I am shooting for. What do you all think about my cams of choice, any recomendations?

TIA

The TR224/112 that you curently have has more trq down low than any of the cams you mentionned.
You could check the Vincy cams (Vinci High Performance), I believe there is a thread about the 047 going on right now.
or there is always the old faithfull from Comp Cams 216/220, .525/.535 114 lsa

GMPP ASA cam has a nice torque curve.

There is something wrong if you have almost 400 RWHP now but only hit 300 ft-lbs at 4200. That should be close to peak tq. Are your numbers right or is your sig out of date?


The more low end tq you have, the easier it will be to spin your tires in first gear. If you're spinning, you're not winning...

Just in case you want to know.

Man, that's some great under the curve power.

my wrong, it makes 375 ft-lbs at 4000 rpms.

I like the TR220-114. My torque curve is pancake flat from 3200 rpm to 5500 rpm it's stuck between 360 - 369 rwtq. I have stock heads. Add some TEA 1.5's and I think you would be good to go.

The TR224 cams typically make better mid range (3500+ rpm) torque than the TR220's. You might also look at your current head selection. I don't know much about the GTP S2 heads, but maybe a smaller port and increasing your low rpm velocity would help get some more low end torque. The 220 cams will definately be better with your 3:42 gears.

Another great street cam is the LPE GT2-3. Doing it again, I would put in the LPE GT2-3 cam.

I agree, check your heads intake port volume=velocity=low end power.I don"t think its the cam.TR 224 is one of the best!!

If you want to try this cam let me know, i have a brand new one: lingenfelter 218/229 .560/.560 113lsa you will love this cam!

Chubby,

Any news on which way you went. After looking at the GTP S2 heads, I just bought a set. I called GTP and talked with them about there S1 and S2 heads. Holy cow! Those are some sweet heads. Velocity is the name of the game, GTP certainly understands that.

Another way to get more torque is to raise your compression.

Good luck.

A smaller Cam won't give you more torque.Like said above, raise the compression for more torque

You could advance your current cam 4 degrees. This would shift the peak power and torque down about 200-300 rpm, but you would also make less peak power. If it were me, I'd consider a smaller cam with a narrower LSA. Something like 218/226, 110LSA +0. This would be very torquey down low and still make good power to 6000 rpm. Idle would be about the same or slightly better than the TR224/224 112 cam.

Damn I was gonna say something was all fuc*** up if your Heads @ TR224 was only making 300rwtq @ 4200rpms. I am making 300rwtq at 2K rpms with my setup. As mentioned before going to a smaller cam will not make more torque your only gonna gain it by going with more compression, smaller head port volume = high velocity = more torque or a larger cam.

Go 383 or bigger if you want TQ.

If everything is ok with the engine, Id get some gears. 4.10's would really wake it up.

Something doesnt sound right. The cam I got is supposed to be weak for lowend power yet it still has no problem hazing the tires in 1st gear from 2k and up. It isnt even tuned either and has mac headers which suck for lowend power. Granted its on regular radials but it doesnt have the front sway bar and 140lbs has been removed off the front of the car so it gets some traction.

I dunno something doesnt sound right.

Make sure cam is installed @108 cl. and install 3.73's.

Call Alan futral at futral motorsports. I promise he can fix you up with what you want he has some of the best cams for low end tourqe. They just got there wed site running this week.You can check the site out but it is best to talk to the man himself cause he knows his $hit!
