The fuel injection is going to be an interesting concept. I would doubt many of your possible customers will go that route at first due to the extra cost. If it was me I would build and test based on your highest mass market potential.

 
Again, agreed, but I have actually sold one already to someone that's going to be fitting it with a carb. I got the casting back from the foundry last week and have just finished all the machining and sent it off to him.
 
Here you can see the final design which includes some branding, 4 vacuum/pressure take-off points (dump valve, fuel pressure regulator, pressure gauge and MAP sensor) and an extra lug at the rear for anyone wanting to fit a water/methanol nozzle.

Looks much better in that picture thanks :-). When's it hitting the dyno?


All being well I should be fitting the engine next month. I'll be running it for a short while without the supercharger before taking it to the dyno, connecting it up and getting the mapping sorted.

Exciting times, let the testing begin.... At least you might have two units being tested at the same time.

 

As a side note, this injection mapping lark takes some serious time to get a state of tune that works on the rollers and the road...

Cant wait to see how this works out for you. 

 

If all is well i will almost certainly place an order.

I've just spent two hours reading your build thread, it looks fantastic, I hope it all goes well at the dyno :-)

i saw this build thread a while back when i was weighing up to go turbo or supercharger for my thirty.

 

i would be interested to get my hands on one of these providing the RR testing goes smoothly.

 

Will be watching this

I really do like the look of this and Im a bit disappointed about it not fitting a 998 but if it's just fouling I personally wouldn't mind working around it but thing I really want to know is boost creates hot air and by looks of the pictures the hole where the charged air leaves the manifold to the intercooler looks quite small won't this creates heat? And the. Trasfur that into the right hand inlet track? With a charger getting hot ontop aswell with the exhaust just below cause hot air rises and the filter is high at the back aswell so this will suck in hot air aswell?

Don't want to seem like I'm tearing it apart I'm general Intrested in this alot jusy want to know the results so will be watching intently thanks Stephen

The idea is you pipe the outlet hole through an intercooler before you pipe it back into the carb.

 

I doubt it well get anywhere near as hot as a turbo gets.

I know no where as near as hot but they still run Hot

its still air being forced through two tight blades then though a small hole

 

and Like i pointed out the air filter will be getting hot air from the exhaust as it gets warm in the engine bay.

I would say the amount of air it sucks it will get very cold for the same reason you get icing up on a suck through. And will always be cooler than a suck through as its passes though an intercooler. If you didn't run an intercooler it would probably a similar temp as suck through, the exhaust and charger heat are there for both set ups.

That's fair enough then I'll see the dyno results from you hubba and the fuel injection run then I may purchase one

Thanks for your input though but we'll see from the results thanks Stephen

Thanks again for all the positive feedback so far.

To keep you updated I should be fitting my engine in the next two weeks and hitting the dyno about 4 weeks from now. Fingers crossed it doesn't blow up!

The 998 fitting issue is something we'll be looking at once we know it works well on a 1275.

With regard to the outlet hole:

1: The internal diameter is about the same as the inlet holes at the rear of a well ported cylinder head. Why have a huge outlet when it will have to go down to this size eventually anyway? All you end up with is an engine bay full of unnecessarily large diameter silicone and alloy pipework making it harder to fit a decent sized intercooler and all the other accessories needed.
2: The external diameter of the outlet is the same as the 'snorkel' on the carb plenum, meaning you can use the same size pipework throughout the installation.
3: Realistically this is as large as you can go and still clear the bulkhead.
4: It's still larger and far less restricted than other kits out there.

We're currently working on a multi-function inlet adaptor to go on the mouth of the supercharger that will allow fitment of an air filter without modifying the bonnet or, alternatively, a cold air induction system with the intake behind the grille.

Im just gonna cut my suck through inlet pipe in half, drill a load of holes in whats left (so it lookslike a thompson machine gun heat shroud) and whack a filter sock over it. Simples
