I am glad that even more people seem to like the car. jlm also wrote on mini2 that he droved it the same day and liked the smooth but huge power it has. The ambient temp of 15degC is not fairly hot, to me at least. I would like to know the numbers the car returns when 25degC. Also from your graphs it seems that your car seems to be runing "hotter", which is a plus for the SPI car IF the measurments were for the same conditions.
thanks

I would like to know what 25 degC feels like as well. We have had one cold winter in New York and this is the warmest it has been here in months.

If you look closely at the IAT numbers you will see that the twincharged car ran consistantly in the mid 140 degF range while my 19% pulley car ran around 115-120 degF.

Remember he is running about 20PSI boost versus my 17.5 psi boost. He is making 250hp at the wheels versus my 190. Given the significantly higher boost and hp numbers one could draw the conclusion that his intercooler is working more efficiently than the OEM unit.

 

Any chance we can get some video of this car in action, interior and exterior, so us international people can get some sort of feel for the pace and sound of this car.

 

I plan on going down there before they go to the show to shoot some video and take some more pics. A little patience is needed because I don't want to get in Hubie's way...

By all means :smile:

... But video with sound from yourself or SPI would be most appreciated.

 

It will be a video with sound. Nothing professional, but good quality. Expect it by the end of March maybe.

I've already started the countdown

 

*still waitin for the video....

i want it nowwwwwwww

 

April 1st...waiting for video :smile:

 

$5800 put me on the list. PM me when you have the kit. I have the 15%, intake, wires and cat back. With plans of 19%, bigger cooler, header and head work and that would be around what $3100. Thats a better deal than the S over the cooper. Well close. :smile:

 

8th of April and still no Video. Come on us Europeans are dieing to see and hear this

 

I will see if I can get some video this weekend. If I can't get it by then, then by next week if Hubie isn't too busy...

 

I talked to Hubie at SEMA, and the car has changed from the initial pics posted. It's pretty impressive.

 

SEMA? Wasn't that in November? The first post about this car was posted back in February. Anyways, I will stop by sometime in the near future and get some video footage and take some new pics...

 

I'm going out to do some dyno work with Hubie today. His car has been out west at a show for about a month and won't be back in NJ for another couple of weeks.

 

Looks like a pic of this beast at SEMA: Import Tuner

Hmm...did they have two of them there? or did someone else make a twincharged version too?



The piping looks different. One car has the tubo outlet going straight into the intercooler and the other car looks like it is going to the throttle body.

 

Good question... I would prefer a turbo replacement for the blower myself, but it looks like it is easiest to twin charge the S, if more than one person has done it. I had just found the pics over on Import Tuner and assumed (bad word) he had just changed his setup a bit.

 

Woah! Looks like the Twincharged is now parallel charging rather than series. This may be a good idea since it would keep the inlet air at a reasonable temp going into the supercharger.

 

the car in BC28's post is Hubie's twin charger; I recognize the intercooler and air intake. It is picced on pg 2 of this thread as well

Interesting! Those do appear to be two different MCS with two different layouts of twin-charging (turbo feeding the supercharger -vs- turbo and supercharger feeding the intercooler).

I have never been a real big fan of turbo's. I think the supercharger offers so much more. The turbo lag is a real drawback. I think the twincharged setup offers the best of both worlds.

This 90 degree inlet from the turbo looks like it would be a very turbulent area for air flow...no? Also, is there a risk of turbo pressure backing into the supercharger?

 

OK two question on twin charged motors. First the twin charged motor that feeds into the intercooler is the air still going through an air flow sensor. Dumb question but I cant see the set up in my mind unless it goes air cleaner- sensor- then a split one path SC other path turbo. Next question on both twin charged cars could you use a SC pulley that is like an AC pulley? Clutch style so that when turbo spools up a boost switch could release clutch and let the SC freewheel. And I know the water pump issue so a elec. water pump would be used. I think I have seen a clutch pulley on a blitz add.

 

yeah, it is 2 different turbo kits. One is being developed with Garret, and will be available sans intercooler.



there will be an intercooler, but it will be extra..

and this is the SPI powerexcel

extra blowoff valve for the supercharger was added by Hubie from the time the last photo was taken.



it also uses a Garret turbo..
