They are great cars for the money. I sold it ages ago. I've noticed MR2 values have gone up a bit lately.

The ad prices have gone up, in reality they are a struggle to sell. I just sold this lovely 2001 Roadster and struggled for weeks to find a buyer. He was the only enquirer, and even he was honest enough to say he knew he'd stolen it at £2200.



Great work on the Porsche, fascinating thread.

That first run looks like it was almost perfect on paper! (barring RT)

Given it's not a dedicated drag setup I don't think I'd be unhappy with anything there.

Great job.

Interesting stuff.

I reckon that car has got low 11s in it.

Hell of an achievement in the building of this thing, through many setbacks and trials. Bravo!

Thanks, it's all been worth while, the car is excellent now.

Going quicker is all in the launch. I've got the power and tyre width so t should be possible to get mid 3's. I'd need to spend more time configuring the launch control strategy on the ECU. There's an advanced set-up I'm not using which has loads of extra tables for fine tuning things like the way the ignition cut and fuel cut are implemented.

I didn't think of it while I was there but I might try starting in second gear with the launch control set quite high, see if it'll get off the line without bogging down. I'd also save some time on the gear change. The gear changes really kill the times.

At the top end I'd need to raise the rev limit so I can get it over the line before hitting the limiter. It's at 7400rpm at the moment and I'm not brave enough to go further on standard valve springs.

Well done Escy! Properly quick car!

Did the PAS fail just after hitting the rev limiter? Pas pumps don't tend to enjoy this and there are a few production roads cars where donuts will equal a failed PAS pump. Have you got room in the frunk for an electro-hydraulic pack? The TRW one has been used many times in Porsche applications with good results.

I think hitting the limiter did cause it. This is the 3rd pump the car has had so I guess it's time to do something different. I've seen the TRW one people use. It would be nice to get rid of the pump in the engine compartment, it was in the way of my boost pipe I made recently, it would be good to free up some space and simplify things.

I've got one issue with doing it, every installation I've seen it takes up space in the frunk, I've managed to get this far without stealing any storage space so don't want to start now. It might sound odd but the way I've hidden stuff away is one of the aspects of it I'm most proud of about the car.

I'll have to try and find to scour ebay, see if I can find something that's a bit more compact. I wouldn't want to go with a fully electric option, in case it ruins the feel.

I've put a video up on YouTube shorts. The outside view is a 12.1 run and the inside the car is the 11.8. On the inside video you can't really hear my launch control as there was an 8 second Escort Van in the other lane. He aborted his run, knew he couldn't live with the Boxster.

Comparison with the old bolt. You can see the design has changed, no longer threaded all the way up.

Confused here

I stripped the drive shaft off my 986. These are all the bolts removed, from one side - ignore the nuts. All are the same as your newer design so not threaded all the way. Car is a 2001 and very original. I had 2 camber adjusters - not sure their name - and a chunky bolt for tuning fork to coffin. Nothing here like yours?

Mine were on the front control arms.

R50 Mini pump may be worth a look. This can be mounted horizontally with an external header tank so quite often packages better than the TRW integrated pack.
