no no no....I think if you leave the hood closed and the F10X hooked up (even with boost). Your car will sniff just fine. I also think it'll pass an OBDII test but i'm not certain. You can always tune the Haltech 2 ways...it has switchable maps.....tune it for boost on map 1, map 2 should be an all NA map. (also good increase the belt breaks). Before you get to where you're going just remove the belt....no boost, car runs NA.

Does this work?? Cars aren't required to have powersteering are they?? I hate your states!! So what if I had to marry my sister. I can run Cat-less!!!

I want. I need. I must have!!

W.O.M.P.!!

yaaaaa ...now Im glad I told you about it. Have you seen the discussion on the link I gave regarding IC's...how much room are we gonna have in the bay, enough for an aftercooler like Vortechs?

Roddimus Prime

no aftercooler....I'm not a fan of water cooling at all.. very ineffective. I am including an FMIC option at a very low cost for those who want the look/gains.

Also, aftercooling is used on the vortechs because they aren't as efficient due their drawing of hot engine oil into the blower and large compressors....Take a look inside the powerdyne blower I posted and you'll see 2 things....

#1. Internally stepped-up gearing @ 3.05:1 ratio....means INSTANT low end boost and gobs more low-end power than most other superchargers.

and

#2. The belt drive elminates all need for coolant/oil/lubrication. No additonal heat added there and the lack of "gears" like the procharger means no fluid for the gearing to bite through.

I think this is a much better design....especially considering that AREA51 used the vortech blower and you see what horrible problems they had.


havent re-checked the thread yet.

Racing Beat

but you forget that when you compress air you raise its ambient temperature, I agree that the powerdyne is more efficient and introduces less mechanical heat into the system, but as was pointed out pv=nrt which is the ideal gas law, you cant compress air without heating it.
Lets get one (yours) up and running, do some serious data logging of intake temps, this that and the other and go from there. Who knows, we may be just fine but until we start testing and going over numbers, we'll have no clue. I will probably add an IC of some sort to the base PSI kit for longevity...

Roddimus Prime

yeah, Powerdyne has already done this. The same blower at 6psi on their Mustang 5.0L kit only added 20-30* temps above ambient.....I think a turbo adds about 200*+ but after intercooling it's only about 80-100* above.....

I personally WILL have the intercooler on my car as I want it to run boost levels above what I'm selling to you guys. For a 4-6psi kit it's really overkill and you could probably save that money for some new tires or a new clutch.

Roddimus Prime

Nice, thanks.

I think a lot of people/doubters thought this was merely a whim for me that I hadn't put any effort into thinking this through or looking for the best pieces possible. That is just not the case. There is about 5X's as much info I could've written about the SC that I didn't because it would take too long. I figured if someone had a question that I didn't answer I could just update the list.

I have been making plans for some engine work in the future, and have been disappointed at the lack of a supercharger option. I am bummed about the loss of the AC. However, the one thing I am waiting for is some real tests and numbers. Are there plans to produce some?

Roddimus Prime

hahaha, yup. Not many people will fork over $2700 without knowing what their getting in return! I'm hoping to have everything fully assembled and on the car for testing in another month or so. I'm doing this 100% out of pocket so it's taken longer than it would normally take me to do this.

p.s. I can't believe how attached people are to their AC. I understand it's nice to have but people concerned with power have to make sacrifices somewhere. I'd much rather lose my supercharger and add 100whp than keep my ac with a turbo and risk boost spiking, excess heat, additional maintaince, etc...

Roddimus Prime

This blower will produce gobs of power down low but power will be made with rpm's.....it will feel like lag to someone who doesn't know what to look for. In all honesty you won't feel "boost" per se. It'll feel more like a V6 under the hood. Power just gets stronger and stronger as you wind it out. MSP's, MSM's, GT's, Redlines, SVT's better watch out!

Blarghman

Yeah, i know the feeling of a supercharger vs. the feeling of a turbo. I'd rather have turbo than a normal *** n/a powerband like ours (especially with no vvtl-i-like-stuff), but then i think i would rather have an SC over a turbo (especially for a better price!).

What kind of effects to superchargers usually have on gas mileage?

Roddimus Prime

when you do let me know. also, let me know how you were able to keep the belt from slipping when the AC comes on. Vortech had a lot of problems with their blowers and AC on the honda/acura models.

I sincerely wish you the best.

Roddimus Prime

Depends on how you drive it. If you stay out of boost all the time you'll probably get much better gas mileage due to the Haltech beng able to tune for "out-of-boost" driving. If you drive like me then you just enjoy the trip and don't worry about the gas bill.

rktktpaul

The problem with the slippage due to the a/c compressor is that the electric clutch is either full on or full off, and when it comes full on the compressor has to fight the initial pressure of the a/c refrigerant, putting a high initial load on the entire belt system. If there was a way to incrementally engage the compressor clutch, you might be able to get around the slippage problem.

Nah, screw it - I'll just put a smowmobile engine in the back to run the compressor.

Roddimus Prime

hahah, I looked into using a small electric motor...1/3hp but it isn't enough to turn the compressor and you still have to overcome the pre-formed hard lines routing. At least when I relocate the powersteering I have soft lines to work with. Makes it much easier. Also t3h powersteering loop will be removed since it's all but useless anyway. Yet another clutter-item that can be removed.
