pressurized intake system

**89gtslb** · 10-23-2006, 12:33 AM

ok so i've been thinking abouth this lately, is there such a thing as a pre pressurized intake system, like not driven by exhaust gasses but an electric pump will pressurize a chamber just before the air goes into the intake manifold, so that when the throttle is opened up the air is sitting pressurized and flyes straight into the chamber. like a leaf blower turbo so that you can turn it on and off when accelorating or for extra hp at time to time. is this a rediculouse idea or....

Not one that actually works. You'll find lots that don't on ebay. Electric superchargers they are called. Belt driven superchargers are the ones that actually do something.

**Pineapple** · 10-23-2006, 10:56 AM

Its called supercharger.
You can't keep intake pressurize all the time. You need to release the pressure when idle.

**MartinGouda** · 10-23-2006, 01:03 PM

he said electric... thomas knight makes them with battery banks

**klue** · 10-23-2006, 06:15 PM

its not a stupid idea, its been done before. as far as pratical application goes, the vast majority prefer turbocharging for obvious reasons. For you to have a pressure chamber feeding the intake plenum, it would have to be a sealed system to prevent the pressurized air from moving away from the cylinders. I think that you would end up creating to large of a pressure drop by simply trying to keep the air heading toward the cylinders. so if you had a tank pressurized to lets say 100 psi by some means. and you ran this on N/A celica you would probably on realize a change of 1-4% positiv pressure in you cylinder, the rest of the pressure would just be releaved to atmospher by traveling the opisite way in the intak. however if you were to rig up some kind of solinoid to shut the intake take trackt and regulate that 100psi, to around 6psi over a longer duration then we got somekind of actual gains. there would be no pressure loss. you basically have a no lag forced induction system which should provide a pretty linear power band. would be nice. in theory that is.

just go turbo.

Good luck trying to find a compressed air system to supply 250CFM at 6PSI. A fan/blower can supply 250CFM or more but not pressurized.
How much PSI you got with turbo/SC when you're idling? Is there turbo/SC system which idle at boost? Could you idle at boost? How about throttle respond? It would be worse then a turbo kicking in after lag.

Just get a nitrous kit. Cheapest power on demand. Its extra air in a 900PSI bottle.

**89gtslb** · 10-23-2006, 08:02 PM

i am going to turbo my car weather it is this winter or next spring, i just though abouth this and had to ask, i think that ill make one from diffrent turbos from other cars mainly because its too expensive to to a gte turbo, i could buy the exhaust manifold off ebay or some thing and then use like a vw turbo

**89gtslb** · 10-23-2006, 08:11 PM

also, what is diffrent about the comp on an alltrac vs gts in turbo wise, correct me if im wrong but isnt the turbo not connected to any electronic component or does the comp control the wastegate and w/e?

-ive never worked this stuff out. "in theory" i know this whole idea is bogus. there is no pratical application yet, i was simply entertaining the idea, because ive though about it too.

A fan/blower can supply 250CFM or more but not pressurized
- yea like those e-chargers i think they are called. lol electric turbo.

im not talking about idling. this system sux, for all the trouble you would have to go through to work something like this out you could fit a small turbo and trumpet 6 -8 psi on your bonestock bottom end with zero lag.

i dont know what the comp is on the N/A cars because i dont build them. the 1st gen 3sgte is 8.8, the jdm 2nd gen i have is 9.1 and the usdm one is slightly less. the trubo is not directly connected to any elctrical device. but the map sensor is connect to the manifold which reads your manifold absolute pressure. the wastegate is plumbed to the turbo and is vacuum operated, when you reach 7 psi it opens fully mechanical.

i dont think its to expensive to do a gte turbo set up. persoanlly i would just swap motors.
the manifolds go from 30-50, map sensor- 50-100, downpipe 50, turbo, 50-700 depending, then the rest of the stuff is small balls.

**89gtslb** · 10-23-2006, 09:58 PM

thank you, i would like a whole s3gte engine it would be way easier but the guy who owned the car b4 shipped in a JDM 3sge engine and after beeing in the car for a month blew it spun the rods and bent the crank, this was the condition when i got the car/engine so i had to get a brand new crank and lots of others ive spent about 4 grand in just new parts for the car all round, so im going to prob get all the turbo components like you listed

**klue** · 10-24-2006, 02:27 AM

wholy crap how did that happen?

**89gtslb** · 10-24-2006, 08:38 PM

the kid drove the car from kelowna to calgary all the time so im not too sure how he actually did this the car sat 3 years b4 i got a hold of it, amazingly enough it did run i olny started it once and it knocked and banged and spewed oil all over the trailor it olny ran for about 20 seconds before shutting it off. too bad i never took any pictures of the engine restoration i really wish that i did because everything was apart and i ported the head myself

**MartinGouda** · 10-24-2006, 08:52 PM

why don't the people around here read my posts? i've shown these pics like 10 times now

electric turbos have been done and have made power...
proof?

**MartinGouda** · 10-24-2006, 08:55 PM

57% increase in tq and 80% in hp

**wil_wil2** · 10-24-2006, 11:20 PM

Thats the largest electric supercharger I have ever seen. But if you want boost in a bottle but dont want to pay for the cost of nitrous oxide, you can use the same system and just run compressed air. It doesn't have the same gains as nitrous but it will still help. Always to remember to shorten your plug gap if running boost or you will blow your spark out.

**MartinGouda** · 10-25-2006, 11:18 AM

compressed air would expand and be useless... just feeding it oxegen would be better

**Pineapple** · 10-25-2006, 12:10 PM

How much boost will you get if you spray compressed air into a 2" pipe with vaccum pump at one end and open on the other?
