developing individual throttle system for mini with cable throttle for racing purposes at http://www.haywardperformance.com, the patterns for casting are being made this week

 

COOOLLLLL

 

Way Cool!!!!!!!!!!!!!!!

Can't wait for the Hayward Performance "reacing cylinderheards and the intake systems. Wonder are will be the price???

Wow, that's a big job. If I'm not mistaken that means the computer and everything would require changing, wow.

Body Motion, http://www.bodymotion.com/ did a conversion much like this, except still single TB, for Nuzzo Motorsports.

You cant have ITBs on an S.

 

All of the worlds fastest cars run individual throttles, normally aspired or with turbo's.
It's the best way to throttle control an engine and have the least amount of airflow loses, so using with a cooper s is just how serious the user wants to be,
pressure plenum onto the throttles and jam boost down it's neck. LHP

 

LHP-
Thanks, great gallery pictures. Keep us posted. Any idea on price range and development time- less than 6 months?
What does your system do with gas mileage? Any negative effect? What about on street driving since this is a race system? Thanks again. We are interested.

You cant run ITB on a postive displacement blower. Its not an opinion, its a fact.

Yes Mr Cheese, your correct I was thinking about turbo's at the time. LHP

 

The intake system is designed for racing (normally aspired) so gas milage on the street will suffer, how much hard to say.under cruise might not be to bad. Time to get the system available to the public, I'd say 2 to 3 months. LHP

Its Dr Cheese. I didnt go to 8 years of Lactose U to be called "mister"

 

Dr Cheese, eh?

Sure, its got a nice ring to it!?

The manifold for the individual throttles will have a wall thickness of .250" for future port work, because the cylinderhead intake ports are very small at the mating flange area. mated prototype intake to local customer's head and did portwork,
will see how it works, when I have info will forward to forum. LHP

It doesn't mean much to me, as I don't understand that part of the car enough...

 

Why not? Just take off the horns and replace with tubes going into a splitter that comes from the IC.

 

Wow, way to revive a 3 year old thread

At least it's pertinent info. How much performance can you really expect by adding this to a Cooper? You've already bought yourself an S with the money.

 

Yeah, I was going to start a new thread when I found the hayward performance webpage, then I searched and realized the guy doing the work had started a thread about it already - a long time ago.

That kind of talk is not welcome in the Cooper forum.

 

Uh?? That doesn't work might be why you uh??? can't do it.


Nice product though. You would end up with a more robust NA motor but at the very least you'd need new pistons to bump CR back up to useful rates.

 

Whoops, just realized that this thread is in fact not in the Cooper forum. Perhaps it should be...

 

This would definitely solve all those pesky front mount, top mount, side mount, sprayed, cryoed, etc IC issues.

 

Seeing that Haywood and HPA are both Canadian, would it be safe to generlize the famed HPA ITB photo to be that of the Haywoods installed?

Now to find the cable throttle conversion discussion I recall from a while back...

Nuzzo's Motec engine management (cable throttle required): https://www.northamericanmotoring.co...ead.php?t=7044

There was a discussion about converting to a "drive-by-cable" accelerator (vs stock drive-by-wire), however endless searches turned up empty. Help please?

 

.... if you want these throttle bodies then plan on at least another $6K for an aftermarket ECM.

 

Thanks for chiming in, I was going to PM you the link to this thread..

Putting the ITB aside for a moment, what about converting to drive-by-cable throttle? Same ECM issues?

If not, could one piggy back the fuel injection duties of the ITB?
