There follows a few pics, a brief report and a dyno print out from Matt Clarke of Roger Clarke Motorsport.

All I can say is AWESOME INSTALLATION & AWESOME RESULTS!!!!!











The power figures are rear wheel figures, so outstanding results.

For anyone not familiar with the history of this car, it was raced last year with a NX kit fitted and suffered numerous backfires and consequential failures, before switching to our system and here are his comments after a season each of using both systems;

Hi Trev

Your system has totally restored my faith in nitrous, it has worked perfectly all year with no back fires or any issues with it at all.
We have had a great year with the car this year winning "ten of the Best" and scooby shoot out, and we were second in the "Time Attack" championship.
We haven't done any Pod meets this year, but did do a 9.59 1/4 at Evington at TOTB in July not bad for a concrete non prepped track.
We may do some pod events next year. I haven't tried the 150 jets yet its been running so well I was reluctant to change it mid season, I may test them now!
The graph from AET is power at the wheels, not bad for a two litre Subaru.

Many thanks

Matt Clarke

Just a shame this isn't a Pro Mod car but a similar result at that level is inevitable eventually.

The Roger Clarke boys helped me out big time at the Pod at USC 2006. I was backing the MG off the tow dolly just next to their big tent in the pits when one of my boards slipped and the MG was left hanging on the dolly with the front spoiler crushed on the steelwork. I was on my own at the time as it was very early on the Sunday. 4 of them rushded over and manually lifted the front of the B in the air and dropped me safely to the floor.
Big up to the RC boys!!
The sad thing is I remember watching "the" Roger Clarke race when I were a lad. Am I too old to be doing Nitrous? NO WAY !!!

Am I reading this right, the fuel injectors are upstream of the nos injectors?

Matt says he's yet to run with 150hp jets - what was he using?

[Noswizard]

Yes that's right and I believe he was using 100 bhp jets.

Utterly fascinating!!

[xxdrac]

isent this the way us bike boys with no airbox do the install as standard :-)

I remmber a convo about the cross fires a long time ago and the venoms with you trev :-) , need new inlet rubbers to try the upstreem set up altho injecting the fuel at inlet rubbers and then some how injecting nitrous from other end of carbs at WOT shooting thro carbs as it were still is something i want to try :-)

It's certainly how Dave Bailey is doing it and I'm sure Dave would admit that he was slightly reluctant to be the first to try this concept but having the pioneering spirit he soon overcame that initial reluctance.

The advantage of this concept on a car is that it can either be done after the carbs (due to longer inlet runners) or due to fuel injection it is less of a problem to inject at the runner entry.

Unfortunately Dave found out (for both of us) the hard and costly way, that injecting at the air intake (through a carb) can't be done in the gungho manner it can on a fuel injected engine or at least that's the case if you intend to launch on the gas, as we never tried it any other way which may have proved to be acceptable.

The worlds best Impreze??? Id like to think so, seeing it up close and hearing it go at various events this year its by far my favourate.

[Noswizard]

That depends how you define "best", as an all round performer with looks and style, it certainly has to be a contender but on pure performance it currently takes at best 2nd place to our other US nitrous kit convert Andy Forrest.
Andy has managed a low 9 using a NOS kit and had been suffering similar nitrous kit related problems to Matt but he's now switched to my system and we're confident nitrous problems are a thing of the past and 8s are a thing of the future.
