  1. Yes a 7.25" Tilton cover can be built as a single, dual or triple disc. The cover is mounted on stands (perches?) and the discs are stacked with plates in between. More discs = longer perches = taller clutch assembly. Buy the disc(s) with the correct spline for your trans and choose the friction material. Tilton makes a couple different friction materials and I've been told that the Clutch Masters 7.25 discs work as well (unverified).

     

    Sorry can't help on V8 flywheel/flexplate compatibility..

  2. Jon,

     

    I have been running a 7.25" Tilton twin disc (sintered metal) for three years and found it to be totally trouble free and actually very driveable (my car still has a license plate). The engagement point is precise but just takes a little getting used to. It's the only clutch I've ever had in the z that has not failed in some way. Mine's mounted on a Tilton flywheel but the flexplate option is better for a track car I believe.

     

    One bonus, you can sometimes find smoking deals on the triple disc version since the nascar guys use them as well.

  3. since I put my Aluminum rad in my Z, my t-stat was higher then the Rad opening. I took a funnel and plug, I drilled a hole in the rubber plug and epoxy the Funnel in it. I stuck the funnel in the Rad opening and just made sure the water level in the funnel was higher then the T-stat. Worked like a charm bleeding the system of all air. Make sure you turn your heater on so you fill your heater core.

     

     

    I use a spill free funnel: 410gKy372TL._SL500_AA280_.jpg

     

    Same idea, easy to use, works great.

  4. I have two sets of Rota RBs, one set with DOT Rs and the other with Goodyear slicks. They have many track days and time attacks on them. I've dropped a wheel off the track pretty hard a few times too. I've also heard of the problems with these wheels so I check them often. Happy to report so far so good.

     

    Absolutely beautiful car! Well done.

  5. What does EP stand for?

     

    E Production (SCCA)

     

     

    Nice numbers Jeff, I've seen your car in action many times, no doubt it's dialed in.

     

    For comparison, my car dynoed 253 whp, 232 tq on a Mustang dyno.

    Specs: 12:1 cr, 3.1 L, N42 with moderate work, Rebello "road race" cam (specs unknown), Mikuni 44s, 3" exhaust, crankfire.

     

    So that puts me at 82 hp/liter and you at 96 hp/liter.

     

    I've been told by several people that Mustang numbers are consistently lower than Dynojets. There is a Dynojet nearby, so I think the next step is to take a few pulls there and compare them.

  6. For some people it's just a "grass is always greener" thing. I know I have that problem sometimes. My 240 has a stroker with triple 44s that makes WELL over 300hp and almost 290 tq. It absolutely rips and runs flawlessly but sometimes the turbo bug creeps in and makes me reconsider everything (damn it's annoying). You're not crazy for considering a trade if that's what you really want. The hard part is deciding. My car spends most of it's time at the track or auto x where I believe my setup is better suited (my opinion only). If I began using the car for more street/trips and just ran an occasional track day then I would definitely build a stroker turbo.

  7. I agree with the comments above about the cummins diesel engines. They have proven to be one of the best every produced for light trucks and are certainly capable of towing your loaded trailer. However, if you guys are getting 17-18 mpg or as posted above by mark.deady, 24+ mpg when loaded, I wish you would share your secret to great fuel mileage. My 03 Dodge 3500 duley can deliver 18-20 mpg when driven very "gingerly" and not pulling a trailer. My best mileage when pulling a 24' inclosed, v-nose trailer and z car is 12 mpg on flat interstate highway at 70 mph. So......what's the secret?

     

    Mayolives,

     

    My truck is an '05 2500 4x4 crew cab. I built the intake and exhaust myself (because I'm cheap). The transmission has been built with a billet low stall converter and a trans-go kit. I also use a Smarty programmer. It has 3:73 gears and 285/70/17s. With no load the best I can get is 23 mpg. Loaded with trailer, Z car, junk, is 17-18 mpg all day long. I've duplicated these numbers over and over again. I've heard claims of higher numbers, especially with the older 12 valve engines. Mine is the last of the HO 5.9L engines. Economy of the new 6.7L is poor from what I've heard. PM me if you want specifics (happy to share).

  8. Worst one? I'll just go with most recent: Welding under the car with no gloves (like an idiot), giant blob of metal falls off and lands on my wedding ring. Nothing I can do but watch it cook my flesh and then the skin just melted off (would that be considered 3rd degree?). Surprisingly it healed up perfectly.
