Anyone running one in their T45? Ive got a turbo setup in the works and need to beef up the tranny. I dont think my Spec2 will work I plan on tuning it to 600+rwhp and need something that will hold that power. What are the pros and cons to the twin disc or should I stick with a single? The price of the McLeod twin doesnt look too appealing Anyone else got a clutch suggestion?

 

I responded to your post on the Coral. Seek and you shall find.

i've had experiance with tilton twin disc BUT not in a t45, but i can tell you they are well worth it....but when you say 600HP, you talkin high or low 600's?

 

A twin disk clutch with a T45 is over kill. The tranny would blow before the clutch let go. Not only that,.. it costs more to replace the clutch than it would to rebuild the tranny. T45 even with a billet shift fork and hardened input shaft is still going to break the input shaft at those power levels if the power is ever really put down at the track. It will live on the street,.. but then why pay the coin for such a clutch when a Spec 3 or DFX clutch will live just as long on the street? Its like buying a TKO 600 for a stock 2v GT. Yeah it will never break,.. but why?

Definately, thats why i was asking his power levers...again i have no experiance w/ t45's, and yes and can tell you from personal experiance they also suck driving on the street ie: the damn tires would spin by just TRYING to drive. All i was saying is they are worth the money WHEN the power is there, like you said the tranny wi,l break before and the damn things are so damn expensive.

I also had a friend w/ a Civic hatchback with a 700+hp Garrett 42r powerd 2.0L w/ a twin disc talk about a SHITTY street driver

Good luck on your adventers to the OP and Hurst, you Def know your shit

 

jim im not going to say you dont know what ur talking about, BUT i always hear about how weak t-45's are. the power iv put threw mine should count for something. now iv only launch my car full out{nitrous and 2step pulling the front wheels} like 10 times, and countless launches on the blower only ...... iv never had a issue with my tranny and im putting more torque then anti-rice will ever make. the clutch i run is a 2600lbs pressure plate and a 6 puck un-sprung ,ceramic. this clutch holds power but sux to drive in traffic.

 

Ill looking toward the low 600s when I get it together then put more boost to it once its broken in. I was planning to upgrade the shift forks and input shaft on the T45. The other option I was thinking about was swapping to a T56. I just havent looked into the cost of doing it minus the tranny.

 

You know me Brian.. I'm like Mark when it comes to a T45. When it breaks I'll just buy another one. I had 3 spare T45's when I finally got out of the 4.6 motors. You can throw a gear at any rshared_pm. But they dont last. That motor you bought from me,.. the one I hurt pretty bad. I went through 6 or 7 of them in that car. I've seen it all. 3 of them got stuck in gear on me from bent shift forks, (It takes skill to limp a car home stuck in 3rd LOL) I had one completely lock up on me at 60mph on the toll road coming out of Cocoa Beach,.. that was a fun ride. I bent an input shaft at DH3 and I twisted another at DH5. And all that was done with a motor making barely 280 - 290.

But be realistic. I'm not saying a T45 is going to blow the second he lays into it with 600. It will last a good while,.. especially if he doesnt power shift it. But.. if he hits the track with 600 and the car sticks,. how many passes do you think it will take for the input shaft is damaged? I've seen LS1 cars break T56 input shafts making barely 500hp. Same with Terminators. 10 spline just werent meant for that kind of abuse.

But all that really isnt my point. In my mind I cant justify spending $1500 - $2000 for a clutch to put in a tranny that can be rebuilt for half that and will only be a matter of time before it blows again. I'm scratching my head trying to rationalize it. With that much HP on tap, he should buy a tranny like my TKO and then get a clutch to hold the HP. And if he's just going to be on the street 99% of the time,. then he wont have the traction to worry about bending the input shaft and in all honesty wont need a clutch that expensive. A Spec 3 or DFX should work for him just fine and both are fine for daily use. And neither one of those clutches are cheap.

I used to bitch about forking over $380 for the DF clutches I liked to use.
