Well, managed to get the nitrous controller sussed out and (sort of) wired in. Although it isn't working. It should pulse the solenoids and gradually slow the pulsing over the time you've set it to, so it eventually delivers whatever you have it jetted to (by not pulsing but just opening the solenoids fully). I've got around 150bhp jets in there.....
An intial test by brookster confirmed it was fiting the gas in but it was a bit of a "suck it and see" moment as the whether I could run it.
I'd done 5 runs, managed a 14.3, equalling the time set by the other corrado when it had the 2.9 in it and decided to try the gas. I cracked open the bottle and flicked the arm switch, but sambo could hear a hissing. I quickly turned it off and popped the bonnet to see the foggers all frosted up!! ARRGGHH! just filled the not running engine with nitrous and fuel....not good. Left it for a few mins with the throttle body wide open then tried to start it again with it still open. thankfully it was fine.
The microswitch I'd fitted to the throttle body was the problem. The throttle mech was pushing the metal arm of the switch off the side of the throttle stop and it was jamming the switch closed. So I retired back to the pits after another nasp run. I bent the arm but then had to do a few more dry runs to be sure it wouldn't jam again.
Once I was confident I had no leaks and it wasn't going to jam on me I hit the gas once I'd got into 3rd gear. The effect was unreal! the exhaust note just picked up into a viscous, hard-edged roar and the car was noticiably faster, so much so i was actually laughing hysterically as I crossed the line.
A quick tweak of the knobs on the controller and went for a proper run with it on from the startline. the result? 13.6, 3/4 of a second and 10mph faster! insane.
I tried the controller in a few positions but it didn't make any difference, it's not working right, but I got down to a 13.58@107mph, which is pretty damn amazing for a totally standard VR6 engine with just a gas kit on it and a fancy gearbox. I was even changing up at 6k...
Much more to come, I might even downsize the brakes and run smaller wheels for drag racing as these yoko's are just far too hard for sprinting.
I reckon it's got a 12 in it....
some pics from GTI festival.
Seat frames were welded in 2 weeks ago.
I couldn't be bothered to cut out the old runners so i just welded to them instead.
Recaro Pro Racer SPG and Simpson 5 point harness.
Rear strap location isn't ideal but I fitted them at the dragstrip so I didn't have time to put them anywhere else, it was simply a case of where I could get at the spreader plate and captive nut.
the Brooksters twisted sanity nitrous controller now fitted. it would appear I am a numpty...I never quite understood the NOS controller, it all makes sense now...apparently the build up time sequence starts again every time you come off the throttle......so i'd got it set on 6 seconds...when I'm only in each gear 3 seconds...which means it only ever deliver half of the full 150bhp shot, apart from the run where i short shifted into 4th and held it, and unsurprisingly that was the run when it felt insanely quick and did the 107mph. so now I know what I'm doing i should be able to set it up better and get some proper results.
I fitted the carbon Subaru Impreza WRC mirrors today. I wasn't so sure about them at first, they look a bit wierd, a bit like a spaniel on a rollercoaster. but I love them now. They need a bot of work to get them to sit flush, I just didn't want to mess about in case I didn't like them or couldn't see out of them and needed to sell them on.
I think I found out when it had no power above 6k too, the old K&N was totally clogged up with filth and dead flies. Binned and replaced with a good old RamAir Pro Ram.
Car now has a dashboard. I've fitted my autometer gauges and rev counter too but just ran out of time to get them wired up. I'm part way there, might get them done at the track tomorrow sometime.
Off to york dragway in the morning, if it's class racing again I'll stay in class D and leave the gas off. then when that stops and it's just RWYB i'll whack the bottle in for some playtime :-)
Then it's home for tea and a shower and off to curborough for Monday. Never driven the car before other than in a straight line. Tracking and camber all over the place, not a clue where to set the suspension, and a potential 350bhp on tap. Should be interesting to say the least!
