newbie with ???'s

Hi, I have a 1993 Olds Cutlass with a 3.4 LQ1. I have a CAI and a custom mandrel bent exhaust. I would like to know what else I can do to squeeze more ponies out, short of a 4.9L V-8 or L-67 swap lol. TY

depending where you live and the your epa laws u can gut your cat. there is a cam timing mod u can do. depending on the year there are performance chips available, underdrive pulleys,high performance plugs and wires(i would wait til later on those). porting and polishing of your uim and lim. kinda high but they say it is a good mod. head job REALLY expensive. that is all the mods i can think of off the top of my head. hope that helps.

cat gut

Laws fail here after about 10 yrs so i took the cat off with the custom exhaust......i had them run 2 1/2" from the down pipe to a high flow baffle then 2 1/2" into dual 9" around stainless mufflers ( 2 1/2" in 6 1/2" out).

Electric Turbo

I've been doing a lot of study into these "electric turbo" units. Most of the ones I first saw are nothing but bilge pump housings that only affort 300cfm @ max . Not sure how accurate it was but my friendly mechanic measured my LQ1 as taking in 268 cfm at idle. So i got to thinking , how does one get the air moving so as to make positive pressure? It took some long nights of web browsing but i may have found the answer. We've all been to the dentist and been gouged at by the drilling/coursing tools. Most of us (me anyhow )didn't , however, know that these units are 12 volt and that they can produce up to 195,000 rpm from a unit the size of a ball point pen.
So, here's my question. I want to know what would be the result if i were to take one of these units and mount it powering a high draw 2 7/8" impeller inside the 3" CAI I made.....what would happ in theory? The specs the guys at the Elec motor shop gave me stated that with the impeller (2 7/8") running through 14 1/4" of 3" pipe (CAI) at full rmp ( 195,000) should produce around the same as 9.6 pounds of boost. Now that number is at idle. He "guessed" that while driving the number could jump up to as high as 11 or 12 due to less drag on the impeller from forced air. If this were to hold true would it be worth while to try this or would ramming that much air into the throttlebody be useless or harmful ?

Those little things don't make enough torque to turn such an impeller at that speed, and I don't think they're even electric powered... I always thought they ran on air.

air/electric

I think your refering to a "Die grinder" only about 26,000 rpm this unit is 5/16" in dia and WILL turn a 2 7/8 impellor at 188.000 rpm. There would be what the motor guy called a "Dry Load" , but because it's air we're moving and we're not trying to compress it ,at idle (no help from air flow ramming in) these numbers I was assured would stand. In case you're curious, the draw on this unit us 6.3 amps at start 4.6 continuious. Down side is they aren't cheap and at full time run only have a life expectancy of about 1200 to 1500 hours.

i did some more asking due to the imput of lacking torque. I went to their web site and e-mailed a ? . I liked the answer i got....."tourque to run a small fan shouldn't be a concern when you consider this unit is designed to propel a diamond bit efficiently enough to grind tooth or bone"

[dykz34]

Sure, it can move air up to a billion rpms... but can it COMPRESS IT? I can blow air through a straw a lot easier than I can blow that same air into a sealed bottle.

That theory is flawed though--I can grind a tooth or bone w/ my DREMEL! And that thing sure as HELL won't boost a motor.

[RednBlack]

I can't see any electric motor stong enough to run an impeller, except a 440 volt, 10 HP. And a long extension cord is needed. And a lot of gearing. And please recheck the RPMs on the dental tool. 195,000 seems way too high. I have one of the best air "pencil" die grinders and it does only 50,000 and absolutely no torque. Plus the electronics to keep the power in sync with the engine would be a computer nightmare.

ty for the input...this is why i asked before i started buying parts lol

Bottom line anything put in the intake stream is an intake restriction!! Unless it's a bonafid turbo charger or supercharger.
