Correction, the quads are supposed to give up to 100% gains in HP, with the right supporting mods of course. BUt you are correct, the quads did need a full standalone system. Most likely the twins will need too cuz like rhyzin said, they would need to use MAP instead of mass airflow.

 

hrm, 100% more HP w/o FI? sounds strange to me.. I could see 50%, but 100%? got any proof (for our motor)

 

yeah im not seeing 100% hp, here is my reasoning...7 psi of boost = approximatley 100+% gains in HP, quad TB's = approx 2 psi of boost...let think about it. maybe if the supporting mods are a rocket strapped to the back or a 50 shot of nos? i'm not saying its not possible, i just don' see how it adds up.

 

lets just say that if these things drop and they dont need a full stand alone im gonna stay N/A

 

I've been talking to Dave about this for 2 years. Hadn't heard January from him, just early next year.... he's probably tired of me bugging him about it

I've asked and asked and asked, and unless they suddenly made a huge change in the design, and are making the 4cyl TBs different from their 6cyl TBs they just finished.... you can use the eManage on the setup that they're working on. That's the reason they're doing it this way- to keep the stock ECU in the loop and allow for a less technically intensive method of fuel management.
No guesstimation on gains from RPW, but I wouldn't be surprised to see at least 30% gains on the 52mm twins. The 58mm twins that they had for another car were supposed to be making around +50%

Porting gives good gains, no matter what. I dyno'd at approx 10WHP gain from my intake mani and Dave is estimating 10-15% on the head based on the previous generations of Mitsu's that they've done. We'll see what the gains are when I'm finished with mine.

quads will run more than $2k because you have to use a standalone and they recommend the haltek E6. street value: $1600 bones. The AEM is still $1300 (I believe) and then there's tuning time.... most people on this board are worried about figuring out the wiring on their piggyback, I don't think there are a lot of people who can self tune a standalone... even Hobie had a steep learning curve for his AEM. Quads also tend to be upper RPM band power makers.... not very commuter friendly, so RPW has strongly recommended that they only be used on the track.

 

yeah i think i could do a good enough street tune on a emanage, with a wideband and egt gauge... until i was able to get enough money together for dyno time... i dont wanna drop a lot of cash for a full stand alone then drop even more to get it working ::double thumbsdown::

 

Boe said he felt some gains from it N/A, but it was done in prep for boost.

Sorry for the delay in getting back.

 

I was just going based on the RPW claims. I was priveleged to work with one guy who actually did have the RPW quads on his Mirage, untuned. Several problems caused the project to die but according to RPWs claims, it is 100% gains. Of course, we had an aggressive cam, RPW port matched headers, FPR etc etc, but that is straight out of the horse's mouth.

Dont forget there are 4 throttlebodies each sucking in an equal volume of air. You are getting more than 3 times teh amount of air, than stock.

 

I frickin love google

Scroll down a piece to see Dave's response from 2002.

so maybe the twins will only make 15% or so on a mostly stock engine...?

I frickin hate google.... now check this out from the RPW site:

Mike, did Dave give you an approx price yet....

 

"To finish off - a well designed motor with qauds will basically produce teh same level of improvements as a turbocharged stock motor with 7 psi boost. The main difference is the qauds do not prematurely wear the motor out and are less tempermental and many other benefits. "

Strangely enough, Dave said you are looking into the 50% gains yet there are claims of 100% increase with 7 psi. Nonetheless, that is what Dave had told me, I will see if I can dig up the emails for you.

 

i forgot what forum i read it, but a 4g93 got the quad tbs, cam, headers, haltech, supporting fuel mods, etc and DID get approximately a 100% gain in hp. you have to remember that psi is a a measure of pressure, NOT the amount of air. with quad tbs you are getting way more air than stock but not at as high a pressure as with a turbocharger, but its not needed. that is why a theoretical 2psi from the quad tb can possibly net a 100% increase while it takes 7psi from a turbo.

eboy, he did not give me a price yet, i dont know if hes ready to even do that yet until he has it all finished up.

 

Dave usually reserves pricing to the US market for US retailers since shipping costs have to be added in. We'll just have to wait until the product is released to find out how much it is going to be.

WADAD

 

Yeah, figures..... oh well.... guess I keep putting pennies in the jar until I know how many I need

 

wad u gonna be doing this... or is this too extreme for your project?
