Love the traction enhancement on the bubble!

Where did your 5 end up Sean? It was certainly a great little weapon, even in low boost guise!

The new toy looks good... are they 4x100 wheels? I thought the RX/929's had different stud patterns. What developments have occurred since you bought it?

Yay a comment!

The MX5 went to a member here who has improved it further with air con and some other comfort mods

The 929 is soooo much work, think patchy time by 15 or so. The wheels on it are 114.3 now, they were re-welded and redrilled from a different pattern, and spacers made up to get the offset right.

It looks a tad more grey now thanks to most of it being in primer.

So far the engine has been rebuilt to stock spec - definately not a rocket, but the big manual choke switch gives a real sense of ceremony.

A whole lot of rust has been cut out and replaced with new steel, a HUGE job, much bigger than I was planning on, but it's coming along slowly, the body itself is fairly good, but the sills were rubbish, as are both the doors, we patched the doors with some plates but I'm keeping my eye out for 2 new doors, I dont feel right about welding so much into doorskins!

Will get some more pics of her up soon.

Have logs of it making over 24psi, but we ran out of map sensor up there so never intentionally ran it above about 21.

Made approx
235@13psi
260@15psi
280@19psi

All without gas, it seemed to be quicker 1/4 mile wise with the smaller turbo and lower powered set-up.

are those power figures hp or kw?

Haha; that has to be HP.

This is a sweet car. Got the pleasure of riding shotgun last year for a flat foot moment. Very schweeet.

12's off the bottle

rw hp

It's not uncommon for MX5s to run 12s in fairly streetable set-ups.
This one and Steve's blue turbo NA6 have both run in the 12s, Steve had a much better MPH, but I can't recall what it was, I think he ran 12.4? From memory Jas's GURGLR ran in the 12s too.

BJ and a few others here have run Turbo NBs (both SP and custom) into the mid 12s with great MPH

Sasso wrote:What sized turbo?

Small
Had turbos from a 280hp AVO to a Garrett 2871R.
Ran 12s with a 2860 almost identical to an SP turbo.

Nice stealth ride Sean, very clean and immaculate. I can imagine the look on the guys faces when you smoked them off the line.

Keep us updated on the 929!

nice looking miata, very sleeperish nd quite an achievenment to be running 12's

tell me more on that nos kit, got any links? what shot was it? dry wet or direct port?

Single fogger wet kit, but set up as a dry kit.
Basically we got the fogger2 nozzle and blocked up the petrol side with a speedflow blank.

Extra fuel delivered direct via the injectors, all setup on auxilery input to the ECU, so the signal that opens the nitrous solenoid also tells the ECU to up the open cycle time on the injectors.

The main rason for this was that a seperate line to run the fuel through a solenoid and in teh fogger would pull a truckload of rail pressure out of the fuel rail and was really hard to control (sometimes it seems to take more pressure than others). Easy solution is bigger injectors and \\blank off the foggers fuel side - Not plumbedin at all.

The kit we used was the Universal V8 wet kit, but using a smaller 32hp jet. The only reason for using the V8 kit over the 4Cyl one was that it came with much bigger, more solid solenoids, which were not only more sturdy, but could handle more nitrous flow if we wanted to go that way in the future. Never really got to set it up properly or race it with the gas.

It was (and I beleive still is) a great car with no gas!
