Chuck asked me to post this for him because he can't get the links to work. Happy to oblige him. Chuck drives an ITS RX7: Part 1 http://www.youtube.com/watch?v=K2h7e62FYX0 Part 2 http://www.youtube.com/watch?v=GZWSZ1neRJ0 Part 3 http://www.youtube.com/watch?v=YGnpMz6WMao Ron

We have two cars, Car1 and Car2. Attached below are the actual dyno plots for Car1 and Car2. The dyno plots were taken on the same day and on the same dyno that is always used to dyno Car1 and Car2. I apologize that Car1's sheet is in ASCII data format from the dyno but it is the real deal...

I’ve finally received the batch of billet aluminum underdrive pulley dampeners for the Datsun L series engines and am offering some for sale. Basically these are solid billet copies of the Euro single grove dampener/pulley that is available; however, this design cannot break. I have had two...

I thought I posted this yesterday but I must have not hit submit. Anyhow, what are your recommendations for a good clutch and pressure plate? I'm dropping the coin on a "pro" motor so I figured I'd see what was out there for clutches and pressure plates. I've been using standard Nissan...

My trailer man needs to know the inside dimension between the front wheels on the Z. Unfortunately, I am 2700 miles from my Z. Can anyone measure this distance or estimate it for me? I need the inside tire to tire distance within a couple of inches. Thanks! Ron

As some of you know I lost a dampener off my 260Z motor at VIR and cooked it late last year. The damage to the head was extensive. I had a deep channel cut in the head between cylinders 3-4, pitting, and severe warpage. My head man was able to salvage the head and press it straight. They had...

Hey David, Don't worry about the drums. Once the FWD weight situation gets resolved we'll write in for allowances for the drum braked cars in IT because we now see that we're at a disadvantage. Heck, when selecting our cars to race who would have thought that drum brakes would be a...

I've got my car apart for a new motor and I'm trying to fix some issues that I have found. First up the cage. On the driver's side, do you think I'll lose any cage integrity by deleting that lower bar on the driver's side long with the tooth pick bars that attach it to the second bar? I'm...

Jeff had a new long block built that will allow him to run a fuel injection setup for the TR8. We've been spending all the spare weekends converting everything over for the new motor - wiring, FI system, etc. Big project for the off season, I think we're probably easily 60-80 hours into it and...

I'm not a wheel guru at all. I've simply purchased old wheels from David Spillman, Steve Parrish, and others to run my Z. But, I'd like to get some new Spinwerks Z wheels in a 15" flavor. The car seems more predictable and happier with 15" wheels. Spinwerks wants to know the wheel pattern and...

I’m trying to replace my worn out and dead front struts on my Z car. The left side strut I removed with no issues – simply took the gland nut off and the strut insert pulled right out. My right side strut is a different story. It is steadfastly stuck in the strut tube. I took a nut...

Before this last weekend’s race at CMP I spent Friday morning on the dyno with the 260Z trying to get some more power out of it. As some of you know earlier this year (detailed in other threads) I suspected this Z might have an "A" cam installed by the builders of the car down in Atlanta and...

It has been a little more than a year since ITR became an official class in IT. I've seen a few ITR cars on track and read about several being developed, but, I've lost count of how many we have in total on the forum. If you are racing an ITR car, or are buidling one for 2008/2009, could you...

I thought some folks would be interested in my 260Z dyno plots so here they are. We’ve never pulled the 260Z before and figured before this weekend’s VIR race we’d get it and the TR8 on the rollers to see what they would do. The dyno runs were performed at a shop here in Durham NC that we use...

Any more news on the Pony Car proposal for ITR? I read in the last FastTrack that the proposal was still under discussion. I'm assuming it is dead or rejected, but thought I'd ask around before pronouncing time of death. Thanks! Ron

I am trying to wire up my Z wiper motors so that they will work. My car has a switch at the dash, but it is not powered and the harness is all hacked up. Besides, I like my toggle switch panel and I'd like to wire them through my 15 amp breaker. I popped the access panel to the wiper motor and...

Z fellows, I don't think my rear drums do much braking and I want to learn how to get them to do some braking. My wheel cylinders and drums are in good order. I use stock shoes (might bemy problem). When I check my brakes I'm getting plenty of fluid back there and my brake proportioning valve...

I'm looking for some more 14" Z wheels. I know a lot of guys have gone to 15s and am hoping maybe to get a set of homeless 14" pieces. My intention is to use these as rain wheels so it is not necessary to have a really nice set. However, I do want to avoid those hubcentric wheel nuts if I can...

I'm trying to make my 260Z as legal as possible. It has always been "mechanically" legal but I've got missing pieces I'm trying to round up. I'm looking for: *The air scoop thing that connects a front firewall to the side wall of the car on the right side. This piece supplies air to the cabin...

I am wanting to make a intake plenum for my 260Z. What I wish to do is make a "log" style plenum that will tie both carbs together. I can then take that log and connect it to a cone style filter out at the front of the engine bay to maybe help pull a bit of cool air in the engine. Maybe the...
