HP and torque limits? Cold side kit

[Hrogi]

This might have no answer. Or it could have already been tested and answered. but I have not found it yet.
So I am asking..

What is the know max HP you could get if you spent to money to do witha Stock miata motor?

I am sure the Cold side kit has a limit. I am wonder what it is...

I took a right in SoCal pats car. It was really nice. it was not in perfect tune that day, but that is now fixxed. SO it might bew a better ride now.
Also there was 2 people in the car, me being 1 of them so that added about 250 extra punds. That slowed the car down a bit i am sure.
I know when i have a passenger in my car I feel it..

I just want a fast car. Fast from 0-60 is what I like...
but as alwasy there is a budget and CA Smog laws.

I see the FFS kit as the only way to go for many reason...

If I set Smog aside, what can I do to make more power with the kit?
What parts are needed.
Here is what i think might be needed.

1. Fuel Injectors
2. Fuel rail
3. Fuel pump
4. IC maybe.
5.Different pullies
6. Computer ?

Ok I just do not know for sure. So any help would be nice.

I am not looking for a debate or flames. just what can be done or expected.

All you would need is a bigger crank pulley if you were willing to set CARB aside.

CARB = ~185WHP
Non-CARB can get up around 210 at the moment.

[Hrogi]

Ok thanks Tom. that helps...

1 Pully 25 HP not to shabby...

[Tom @ Fast Forward]

I do what I can. Pulleys are not too expensive either.

[bogey]

The 94-97 kit already comes with an upgraded fuel rail.

[Hrogi]

Came up with another question.

How much Air do these Cold side unit put out. in Cubic inches or liters?

[Tom @ Fast Forward]

The blower is 1 liter or 62 cubic inches (MP62) per revolution. It spins at Crank pulley/nose pulley * RPM. With a stock 105mm crank pulley and 65mm nose pulley, it will spin at 105/65 * 7000 * 1L = 11,307 LPM or 701,034 cu-in/min or 405.6 cu-ft/min (1728 cu-in in a cu-ft).

Yup you remember right. The car at that time had a bad alternator on top of the fact that it was running PIG rich. tip in was ~10:1 on the AEM which could have actually been worse since I think 10:1 is as low as it shows. It now runs crisply with a 115 pulley and a pair of PC-Pros. I bet with a stand alone, bigger injectors (not too big) and a better fuel pump and Tom's fuel rail you could get a good 225 out of the coldside. Problem is most folks would hate to risk the stocklike drivability. In time though someone will test it.

[Hrogi]

Thank Tom...

I just wanted the 62ci number... but you also put in more data than I will ever use in my life...

Yepper Pat I remeber... I think I need a another test drive..
but this time you drive... I am not use to your clutch...

Well for now that 185 CARB and 210 non bard change pully is the way I want to go...
After reading Track Dog website. and he saying 225 RWHP is the max you want to run.. That sealed it for me to get a FFS.. those number relate to having the car last the 200K on boost by the way...
if I want a track car that got rebuilds then 300 or more would be the goal..


I know I want a 400 HP car, but that will not happen...

So I need to get a 200 car that wil last for even and be happy with that.
Learn to drive it and enjoy the saving...

Also staying Carb legal is nice...

but now to save up the cash to do it all.... the price is right...

you can not get this power for less and have Carb.. i checked..

[Tom @ Fast Forward]

The model numbers for the Magnuson blowers denote the displacement in cubic inches. M45 = 45 ci, MP62 = 62 ci, etc.

[Hrogi]

Umm boy you think i would have picked up on that...
but no..
thanks for pointing that out. I had missed it seriously...
I would about my self at time...

Hmmm... check (FM Link Obiwan), check (RC440s), no to fuel pump, and check to Tom's dual feed fuel rail! Add in water injection, and that's the setup I'll be running in April sometime. I don't expect 225, but maybe if I move from the 115 pulley to a 120, or... ? ;)

Hi Tom. When does the size of the blower begin to show diminishing returns? What I mean is; can I, as a car enthusiast, expect a larger blower to be developed in the future?

Rafa

[Tom @ Fast Forward]

The MP62 is all I will be selling. It could make 300WHP and i won't be selling kits anywhere near that.

Hey Gord, are you running WI in lieu of e-cool? I wouldn't think you'd do both? Does WI have an advantage in your setup?

[bambam]

Yes I would like to know too. I have contemplated buying WI however running E-cool... having combination fuel and water being injected at the sametime would I get any benifits? Would one hurt the other sorta speak?

I am running a 110mm and not sure what whp I am getting "yet". But still believe I can run at least 115mm and would llike to get to 120 mm "SAFELY"

If you spray the water injection pre-blower it has the effect of helping to seal up rotors better and cooling off the blower/intake. This couple with the E-cool would probably allow for a little more power.

AND the mind starts to ponder ??????????????
good question though, WI & E-Cool ????? I know WI pre blower has been discussed at length on M Net. and as usual NO clear answer, and I'm thinking a lot has to do with your area and the relitive humidity. Here on the Gulf Coast the RH runs from 60 to 110%, where as out west the HR is < 10%
