300-400 rwhp on stock tranny/clutch???
 

I'm just wondering.......I'm not there yet (400 that is), I figure I'm around 310 now. I'm thinking of spraying 125-150 horses and I'm not sure what tranny/clutch set up I'd need. Right now I'm still running te stock tranny and stock clutch. I don't run it hard too often. I'm thinking the Tremec TKO and Centerforce DF would be overkill. What do you guys think/recommend? (the reason I'm asking is I could always use that extra $$$ saved on something else. Thanks for your $.02!:)

Pay me now or pay me later...

I dunno, I broke my T5 with 330rwhp (NOT drag racing, but roadracing) pretty quick. Like within 18K miles.

Went with a TKO and never looked back... :)

Thanks Darius. But you don't think the TKO is overkill.....would I be ok w/ a 3550 or even a heavier duty T5? How about clutches....would a King Cobra handle up to 400rwhp?

I have no personal experience with this, but I've been told that the 3550 is only slightly stronger than the stock T-5. The TKO is supposedly much stronger. Besides, the price difference between the 3550 and the TKO is nominal. If you go with Tremmec, just get the TKO because most of the cost is in installation anyhow.

If you are going up to 400 ponys, get the TKO. It's rated up to 525 ft/bls of torque. The T5 is only up to 320. The 3550 is just a little bit stronger then the T5 but not my much.

Which clutch kit?

I would go with the RAM 900. It holds up to 500hp.

The 3550, and TKO are the same except for the input and output shaft. That alone makes the 3550 much stronger then the t5 because most people break internals on the t5's. The 3550 is underated IMO. Take this for what it is worth, but I ran low 11's w/ slicks using a 3550 and a centerforce clutch all day long.

Also, if you get a TKO you will have to get a new crossmember, yoke for the drive shaft, and bell houseing. There are few companies that make clutches specifically for the TKO. :rolleyes: But the ones that do, are good.

Oh, and it come with the shifter.... The T5 shifter won't fit.

If it's not obvious, haven't made too many passes w/ slicks w/ my stoc tranny and clutch. :D It's still in good shape actually, but I'm planning on running DR's on the street, full time (again).....ad w/ the added hp/tq, I think I'd rather sell my tranny before it goes pop. What is a used tranny in good condition w/ 12k on it worth?

You don't need to replace your T-5, it don't matter they all break, I've ran over 170 passes on my 93 T-5 at the track with a basic motorsport clutch, 91 of those passes were on a 150 shot out of the hole on spray and slicks.

Tremecs slow you down too, ask Bob Cosby.

Why would a tremec slow you down? Are they alot heavier than the t5?

I run 11.19@124 with a World Class T-5 Z7003 and have not had a problem. I run slicks and launch off of a MSD 2 step at 4600 rpm's and it has pulled 1.60 60 ft times. I have a Motorsports SVO 10.5 clutch. I have raced these parts for 2 years with no problems. Just my .02 cents

got this from the corral

"I agree. 3550 is good for racing with drag radials at the power levels of 400rwhp+ If you want to do clutch-drop launches on slicks and WOT powershifts, move to the TKO. And the TKO requires the clutch disc as mentioned, in addition to a different driveshaft yoke (larger diameter, greater spline count as well). "

While chasing a driveline vibration I borrowed a 100K+ T5 to see if it was the trans. Took it to the track sprayed 125 out ff the hole , 1.57 60 ft.s, & carried the front end all night. I would have just left it in if it had a reverse. Now running world class T5 with ram 900 clutch. 11.90's on motor no trouble. I hear a lot about the tremec, but never seen anybody running faster than mid 11's with one. When the T5 pops I'll probably put the spray back on & go jerrico.

What's the price of a world class t5 and who carries them?

Thanks 1bad89. For another $200 could get a Tremec 3550. Is it worth saving the $200 for the worldclass t5? What makes the world class t5 better than the stock t5, anything?
