Ok, does anyone have any suggestions with running the Tilton clutch and flywheel at the track?

I've got a track model with DRs on the stock rims but it's time to replace them. I went to the track with the Tilton for the first time this weekend and things did not go well. Not only could I not get off the line better than a 2.3 60', at times, I was spinning all the way through 3rd and I couldn't spray until 3rd at the earliest. I think the track might have been a little damp cause of the 90% humidity, but a 14.2@106 is not something I like.

I'm having a lot of trouble now that I can't slip it very well. I was planning to get some Weld wheels with MTs, but I'm not even sure if this car will be able to use them.

 

I have pulled 1.8 with my drag Radials and 1.7 with my M/T streets... No offense but you have to learn how to launch with your clutch setup. The Tilton is not the best choice for the drag strip... You can run a 15x 9 or 10 with no problems and a 26x9 ro 10 slick with no problems but you are at risk to break your axles... I broke my cv joint once so far and that was launching at about 5200 rpms on 9.5" wide M/T street ET's .....

 

I understand that I need to practice, I'm asking for people that have experience with the Tilton or any other non-slippable clutch.

Notice that I said track model, I can't run a 15" rim on my back wheels.

 

Sorry if I came off harsh, not my intentions. The CM clutch that I am running is also impossible to slip.. It obviously takes practice.. Since I broke my axle dropping the clutch at 5200 on the M/T's, I would reccommend about a 3000 rpms launch.. It just takes the perfect balance of starting to apply more gas right where the clutch strats to grap....

 

Sorry I cant give you advice on the Tilton cuz i dont have one, but nice trap speed. What other mods do you have?

 

what's the problem w/ the clutch is it grabbing too hard? launch at a higher rpm, the centripal force will just naturally cause the clutch to slip more.

 

That's not how this clutch works, please, I'm just asking for experienced people here.

 

I have raced with the Semi Street Tilton but no track time. Maybe I can give a little insight. I imagine at the track it is going to be extremely hard to get going without spinning the wheels. For me a pretty good launch came at about 3k rpms but I had to be precise because the tach drops FAST. Usually I would rev up to 5 and release the clutch @ 3k on the way down.. once I got going I could feather the clutch a little bit to control the wheels from spinning. I'm sure second wont be any easier, but you should still be able to feather the clutch in second. Its going to take some time and preactice to get the routine down.

If you have the semi street I am going to tell you now..that clutch is very tough.. it can take a beating cause lord knows I gave it one and had no wear on it.

 

I went to the track the other night and also had a hard time but I was only running Kuhmo MX tires....275 wide...... I spun a little through 2nd.....Keep in mind I also have the 3.917 gears besides my tilton street clutch.... I slipped the damn thing at about 2500 RPM I belive with a better tire... my 60ft was a slow 2.25...... Im gonna be buying a better 275 size tire soon...hopefully it helps.......


I previously had the rally clutch and slipped that also...even though it didnt like it..... just prepare to inspect the clutch at 10,000 if you force it to slip....

 

One of Z owners here in San Antonio was telling me about you not too long ago. The reason it came up is because I just recently installed nitrous myself.

You have two main issues going on with your launch. With the Tilton clutch and flywheel you lose a great deal of rotational mass which helps the motor keep momentum during launch. This within itself is not a bad thing because it can usually be offset by raising the RPM's a bit, however you need to be able to slip the clutch in order to control the higher elevation of power/RPM's. The problem is, you can't really slip the clutch much with your setup. I'd like to go into a bit more detail, but seeing how this thread is old, I am not even sure if you will see this.

I personally am using the JWT setup and am able to pull 1.9's for 60' on Goodyear F1's (non DR or ET streets). I run 245/40/18's and believe it or not, I pull better 60' times with the tires at 35 pounds than i do at lower pressures. I believe that with all the negative camber we have, lower the pressure seems to make things worse. At least in my experience. I also went to a bigger tires and that was worse as well.

 

Done12many2, first off... Semper Fi Devil Dog.

Second, I'm just curious what kind of times you are running with your setup.

 

Semper Fi. On the 4th of march, I ran a 13.07 @ 107.58 with the Maximizer adjusted to a maximum of approximately a 35 shot. Yesterday was a bit warmer and took me a bit more to get a 13.06 @ 107.45. Keep in mind that I am running these times on a set of regular street tires (245/40/18's). Of course with a set of ET streest and a 1.7 or better 60' time, I would be well into the 12's.

 

Definitely saw this post and thank you. I just had a set of PS2s put on the car, so I'm not going to the track again for a while. I am gonna pick up a set of those 16" Weld wheels and MT ETs. Do you think these will work cause I will be able to launch at a higher RPM? Also, are you talking about Josh in the Blue Z?

And on a side note, here's the end of the DRs. www.clemsonpilot.com/joez/Zburnout.wmv

 

don't even bother going to the drag strip w/ street tires and a tilton. You'll have terrible times because you'll be spinning through 1st and 2nd. Even before the tilton I would spin through first and second.

get some ET Streets, you'll be very satisfied. last weekend I wasn't able to get hooked up and I got 1.9xx 60' times consistently. my best ET was a 13.66.

I was trying to launch at different RPMs and I still was getting the same 60' times. 4000, 4500, 5000 & 5500. I think it was mostly because I just wasn't getting them heated up right. Also I had them aired up to 18psi cause I didn't want to float around to much. And for the last 3 runs I brought them down to 15 psi. but still got the same 60'

and yes I have a tilton

 

Appreciate it.

 

Yeah a tilton needs FAT tires........ but i think once us Tilton owners hook up we'll be hittin some nice numbers..... a LSD seems like a must mod also.....

Im thinking a Stillen S/C
NISMO LSD to complement my 3.917
and some slicks......
