Hi all

We are looking at releasing a blow through kit for carb and SPI minis ( not sure on MPI just yet) and looking for a little feed back and views from people either looking to supercharge their mini or just curious about how the kit will work.

We have booked a stand at Bingley this month and will have the car on display. We are hoping to have prices available by then and be on hand to answer any queries potential customers may have and possibly start it up a few times for people to see and hear it running (if allowed).

From this poll, we are looking for people to give reasons why they would choose one kit over the other so we can try and match typical demand, but will also sell parts of the kit separately for those that may have already collected parts over time.

For anyone curious about what the kit looks like, the car is being featured in Mini Magazine this month (out on 14th Jan) and might give an idea of what to expect before the show on 30th Jan.

Any feedback will be much appreciated.

Thanks

Dont really know enough about blow through so i would choose suck through - sorry

I suppose if I was in the market for a blow through kit I would want some detailed information on your website like a FAQs section - fuel consumption, comparison with suck through and turbo in terms of power, reliability, boost potential etc, and I would suggest making a real effort to provide some really good instructions for people to be able to fit the kit themselves.

As with some other kits the build quality isn't that great and the kits really aren't 'everything you would need'. It goes without saying that the quality of the components needs to be excellent, a comparable price, and as you've already said - it would be a good idea to sell the individual components.

In summary, I'd like to see good information/instructions, quality parts and realistic pricing, and of course good after sales support because there will be snags...

Good to see some entrepreneurial spirit in these dark times!

ive already had a suck through system so id have to say blow through for a change and to acheive more power

[Darkscamp]

Just in the process at starting a blowthrough system on Minx's mini.


What sort of bits will be in the kit?

[TopCatCustom]

If you are developing them from scratch why not build one of each and rolling road both, drive both and show comparisons, then rather than ask what people want (who probably won't have a real reason for either) you can tell them which is better, with facts to back you up!

[roofchoplofty]

Great idea, wish you the best of luck.

Ive had a suck through supercharger conversion and had nowt but hassle with the thing, however it hasnt put me off and so now looking at the blowthru version with interest, i still have bits and pieces left from the old kit ect so would be interested in what parts are availible and cost. Hopefully see you at bingley too pick yer brains.

Cheers


Heat issues are a big thing with suck thru, is this reduced with the blow thru?
Also fuel economy figures ( not that im too bothered ), if its that much fun you dont mind sticking the extra pennies in the tank.

Im looking to supercharge over the summer and would much rather have a blowthrough kit.

I do have a good comparison that can be used as the car was first setup with a weber suck through and run on the same rollers that has been used to develop the blow through.

Good luck

Also if i remember correctly, its not a half arsed attempt as suckthrough, he made big power compared to the normal suck through charget setups. If i remember correctly!

The heat difference between the suck through and blow through is massive. After a run in the suck through, the charger was red hot, you couldnt touch it. The blow through just about stays cold. I know that where the blower is on suck throughs isnt great as its going to also retain heat from the manifold. I guess another plus point with a blow through is the charger is at the front of the enginge and will get a good cold air feed. Also the ability of being able to run with an intercooler will help cool what heat does come from the blow through charger and if needed, give the ability of running higher boost and reduce det.

suck through superchargers cant produce as much power.

intercoolers cant be used with suck through chargers,

suck through chargers are *******s to get started

plus point of suck through chargers is the carb dont suffer from heat soak lol

also suck through chargers gives you somewhere to put the charger,

[johnnysti]

For those that have asked (and an oversight from me) the kit will be using the Eaton M45 super charger. We are also looking to develop another blow through setup and will be hoping to offer a Rotrex kit as an option. This is still in the early stages of development so initially the Eaton kit will be the first one released.

Hope this helps

I would be very interested. Hope it works out.

The setup you have is by far the best, if you want to run higher boost i.e. the use of an intercooler smaller pulley extra. On my setup the charger doesn't get that hot due to the fuelling being rich, this helps keep things cool. However I'm going to fit a SPA boost/Air temp gauge soon to see what the temps actually are relative to the boost being used.
