Title: Its almost finished

Basic update is the FC made 421bhp (fly) at 1 bar on sat, thanks to a cancelled day we managed to sit and play with the map for a while.  Its helped that we think the engine has a mild street port.  Graphs will follow when i get them off the dyno.

Its been running 360ish for a couple of weeks and even at that its a bit scary. Took it out today to go get a quote to get the external WG plumbed back in (its so loud its actually painfull in the car) and its deeply scary, it will on occasion spin up the rear in 3rd, and by god its fast!

Things to do now are get it weighed and corner weighted (and be disapointed i\'ve not made my 1000Kg aim, then start with the carbon fibre bits) and get it back to the paint shop to make right all the things they ****ed up the first time.

Hopefully then i might even get to do a track day in it! Lets see how long it takes for me to blow it up!

I\'m really pleased with the way its turned out, thanks must go out to Prof and others on this board who have helped out, and of coarse my friends Mark (who helps me out on the dyno) and Ed at Fusion motorsport who despite never having even seen an FC before took on much of the reassembly of the car.

I\'m afraid to say the Cab has gone to Seven heaven. :(

*gives sticker for most improved FC* lol what rear wheels are you running?

I just checked on the rx7 store for the T78, it says its max power RWHP is 430, so 421 at the fly is pretty good :) and thats only at 1bar :D

I\'m not entirely sure, I bought the whole set for £200. Rear tyres are 255, however they are all Firestones straight from Japan and are not what i\'d call the greatest in the world.

Excellent power figure - bet it\'s a white knuckle ride now ;) :driving:cool
 
It\'s so sad to see that cab going on the loader - still bits of it will live on in mine - many thanks for letting me pick at the skeleton before it went off :)
 
Be interesting to see the power curve from yours - it\'s a big turbo - but it sounds like the car breathes easily and has no problem spooling that thing.

The engine was a freebee that came in the cab, its been rebuilt by someone oop north, maybe Pip, but he does not recall the customer. Its a bit of an unknown so i dare not push it over a bar. If it manages a year on track i\'ll push up the boost.

I should also thank the chaps at RXmotors and REworx for answering my often inane questions, and supplying bits that we um.. lost and broke.

Prof, curve is not that bad, will back up the dyno and pull the graphs off when i can.

I need to order a jacket for the turbo hot side as well, the under bonnet temps are stupid.
