i would like to know what kind of engine mods/tweaks your all making?
and what the power gain is
the 350 i was gunna get, is gone. she dudes ex wife gave it to her little nefew

so im back to increasing a 2.8L 's power
ran across something called a e-ram
and it got me thinking,
......hmmmmmmm
electric supercharger......
ok here goes
i know few would like this set up but.....
ok have a onboard air compressor, half way small size, supplying a smallish tank in the hatch
with a insulated air hose running to either to the intake
have a water filter mounted inline somewhere
and some sort of switch to allow so many psi (im sure they make these somewhere)
hook the power up to the air compressor and there ya go
instant power
just try to keep it down and toy around with it
also
how many cfm of air would be needed to push a 2.8L to 200 horses and about 230 foot pounds?
if i was running accel injectors, a differnt fuel pump and a regulator on that,?
headers also?
3" single exhaust going to a flowmaster single in dual out muffler?
i know it folks this one sounds brain numbing but......
turbo's and superchargers merely push more air in
and get me wrong here
but air from a air compressor is COLD
so thats something up from a non intercooled turbo at least
bye for now

 

Just get a 3.4L engine with a nice aftermarket Cam in it and don't dream about a turbo or blower because they don't make them for our cars.

 

I've seen those compressed air systems in some of the import magazines. But honestly, I don't think it'd be worth it. You'd have to have a big *** tank to hold the compressed air. Then, you'd only have enough air in the tank for one pass. You'd have to have a valve in the intake that would open to the stock air intake for normal driving, then close for the compressed air. And realistically, people have been using nitrous for decades. Don't you think that if it was as simple as using compressed air, people would do that instead of nitrous (sure sounds safer). All in all, I think it'd be a bad idea (and waste of time and money). As for the eram, those things are junk (search for the previous posts on it). They only create 1 psi of boost, some of the time. $300 for 1 psi? For that much money you could do mods that would really give you some HP. I still haven't given up on the turbo idea, and I'm trying to find a way to do it under $500 in parts.

 

look for a mid to early 80's gm turbo i got mine off a riveira for 60 bucks at a junk yard
spins perfectly no rust on it or anything

also
anyone know how much air the a/c pump puts out?
surprised everyone here just says swap in this or that
why not tweak the motor we got?!
that is what some of the v-8 guys do
i dont know about all of you, but i dont like pulling a motor out and then putting a differnt one in
its time consuming, and costly
but like 500-600 in mods,
well
cams, and the ussual would work to gain power,
so anyone know any good hott cams that someone with a 2.8 has? what kind of felt differance do they have?
also i did say a onboard air compressor like th eones air shocks have?
you could technicly adjust it to give out like 8-10 psi so that would be boost right?
poor mans turbo ?
lol
POOR

has anyone on here REALY mod'd a 2.8L?
or do ya all just pop a k&N into it and slap on a type r sticker an go?!
no flames ment but come on
lets share ideas that dont include a motor swap
as far as a motor goes, it needs the following
fuel
air
and spark
increase all three and your increasing your power
big injectors, a high volume fuel pump and a regulator and you got your fuel there
petronix coils are amazing on the cars ive seen that have them
so there is your spark
no air and air flow from intake to tail pipe
boring out the tb porting and polishing it all up would help also
cams so forth
but it would still be the tiny pistons and cilinders pulling the air in, not to effeciant
so we need to find a way to ram more air into the motor
compressed are would work, technicly if not practicly
turbos yes if your willing to spend the time behind a welder
s/c's yes but you have to shell out a TON of cash
and peeps
anyone know about taking a turbo and slapping a pulley wheel onto it then mounting to the a/c mounts ?
and also if you rip the cataletic converter out of a 86 camaro, would you still need the smog pump?
i pulled the cat off my regal, and then cut the smog pumps belt drove it around the block a few times, and if anything it ran a LOT better, certanly wound up faster

 

also
i only have about 500 i could spend on the motor of the car
im going budget all the way across the board with this camaro
cheap stereo , jensen and lightning audio gear
radar laser detector ( a must since my last one was jacked)
lil interior tweaks, scanned white face guage covers, that carbon fiber sheets thing
and tint
its already got a nice set of 15 inch chrome wheels on it with PERFECT tires
and the motor has jus 70 sum thousand miles on it
the compression is still at factory specs,
distributor is good, but a higher voltage coil couldnt hurt the slightest

 

A lot of people here have done some, if not all the mods that you listed. However, if I bet 95% of the people that bought a v-6 fbody did so because of money. They're cheaper to buy, insure, and are better on gas milage than the v-8s. So are there gonna be a lot of people on here that have dropped down several $1000 on their car's performance, probably not. The AIR pump on these cars (at least mine, not sure about all years) routes air to the exhaust manifold, not the cat. But if you don't have emissions testing where you are, then you can remove it. Although most people report very little gain from it. Now if you were looking for a place to mount a S/C, then that may not be a bad spot. The aftermarket support for our cars isn't very good, so don't expect a wide variety when it comes to things like cams.

 

crane makes a couple cams, but there emmissions legal :P on that
140 out of summit
ive ripped heads off of motors before, done a couple swaps and have assisted in 3 complete rebuilds, i know i can do just about any type of repair/swap/power booster myself
and thank you for not saying
put a v-8 in it
lol
im a HIGH RISK DRIVER
ROFLMAO
ever have to pay 105 for insurance? how about liability?
it sux
and i think from the way the motor wound up its got a LOT of room for improvement
and therefore more power.......
yea and count the smog pump as being gone soon as i take possession of the car
know anything about injectors?
accel makes some 30 pund a hor ones for lt-1's ls-1's and so forth
that some way to push a crap load more air in, and let it back out just as fast, and a better spark might be just what the doctor ordered for the 2.8L TPI

 

People who have upgraded their ignition systems have reported better throttle response, but not so much of an increase in power. You can put in bigger injectors, but without an increase in airflow, they really won't do much. The key to getting a lot of power out of these engines, like 200+HP, is gonna be to increase the volumetric efficency. To do that, you're really either looking at forced induction, or nitrous. Both of which are do-able, it's just gonna take some effort. But if you're looking to spend about $500, you're not gonna get into too many "serious" mods. But if you're real familiar with this sort of stuff, you may want to look into porting and polishing the heads. Do a search on it, some of the people that have done it had really great results. Oh, and I'm with you all the way on doing stuff on a tight budget. That's why I bought my camaro, cause I can afford it! I don't have a $2500 stereo, because I shopped around and didn't buy big name brand stuff. But I'm not interested in dropping down serious amounts of $ on Rockford Fosgate amps, when all I have to do is say "I've got two 600 watt amps, and that's just for the back seat" and people think I'm cool. And all the music these days sucks anyway, so why bother spending a ton of money to listen to crap?

 

roflmao
i like SOME new music
but ya cant beat the classics
anyways
im going over to my uncle garage tomarrow to finish ripping the a/c crap out of my regal
im going to get his air compressor up and running and blow some air into my air cleaner
not realy testing it but to see if the it makes the car putter out or what
like a concept test or something
anyways walmart had air pigs for 15 bucks
and a cheap lil 12v air compressor was 40 bucks, plus fittings cost, hose wires ect. plus ya'd need some sort of preassure regulator (any ideas on that?) plus, a water filter, and a fitting to install the air hose directly into the air cleaner, before or after the air filter, id go after just to make sure theres nuthin bad getting into the motor
yea man im spending like, 400 on my stereo system
tinting it all myself so :P
budgets ar ekinda cool
kinda not
lol

 

if you get pictures of the built and running turbo hardware ill send you a copy of the bin im working on for a 2.8 project i have brewing. the bin should allow ou to run the boost and compenstae for the extra fuel. however i will tell you striagth to yr facde that threr is no way i can make it even close to perfect.

 

buickboy, I wrote you a long *** reply, and then my computer froze when I tried to post it Basically, if you want help with a compressed air setup, let me know, although personally I don't think it's a viable idea.

 

Last week, I started looking into the possibilites of converting a turbo to a supercharger. (See the "turbo questions" thread) So far, I grabbed a little Mitsubishi TD04-09 turbo for $10 that works. I believe that the biggest problems with converting a turbo to an s/c are: Driving the turbo at an appropriate speed off of the crank, mounting the turbo and driving setup, and getting a decent sized turbo. The last item is my biggest problem. At this point, I think the turbos that I have seen in the Chrysler Turbo 1 cars and this TD04-09 that I have are too small. The larger the turbo (and the larger it's turbine/impeller), the slower it will have to turn to move the same amount of air. I've spoken with a few folks around here who have a lot more knowledge than I do and they seem to think the same thing, although we could all be wrong. I need to go and look around the yards for the largest turbo I can find. I am also going to look around for superchargers, the ones that Buick used on some 3.8liter engines and some that ford used look like they might fit in the engine bay somewhere...

 

there is another good lil v-6
the 3.8L buick motor
mmmmmmmm 231 cubic inches of power, seriously!
when i was tweaking and tuning mine in the regal it was making some very impressive seat of your pants gains
headers realy did help the low and high end,
the edelbrock performer package SERIOUSLY helped, i mean like WOW
the car was brain dead, i had ripped out the comp of it it had no cat and no smog pump belt on it
i had about 1mm or so milled off the heads surface to help bump the compression up a bit it helped a lot too the motor certainly wound up a hell of a lot quicker
i used a adjustable vacum timing advance module from crane cams to make full useage of the spark curve and had a summit high energy coil in it to help also,
it would haul *** on the highways
but those cars (gm "g" bodies) are geared fo rhighway driving, very high gears in them like 2:41's and the such
ive seen severaly with built v-8's just screach the tires a bit.
if your a injection junky then you can swap in a 80's to like 92?! fuel injected intake manifold and all hardware from another 3.8L of those years,
also as far as i can tell the 80's-early 90's FWD 3.8L's have the same trans bolt pattern so they would make apretty nice lil swap if backed by a 200 R 4 transmission
i was forced to change out my timing chain along witht he covers gasket today when i yanked the a/c stuff
and lemme tell you
WOW
tons of pull to the ol girl
compression is a hair over factory specks, so i think the rings are still good so i might just change the distributor, get a new set of headers (one of mine rusted thru) and a 200r4 trans with a shift kit in it and swap IT in
goddam
wish i could just decide!
but this way i already got the motor, i know whats been done to it, and what NEEDS to be done,
just need to get some new headers, and another 600cfm edelbrock performer electric choke non emmissions carb again.......

 

3.8L buick engine in an fbody=TTA. Now those things were/are FAST. But you can't get the whole 3.8 to fit, GM had to use heads from a different engine to get it to fit between the strut towers. Of course those engines were turbocharged too, so I'm not sure what the results would be with a stock motor. If you've to a 3.8 in good condition, maybe you want to try and build like a TTA replica. I suppose it'd all depend on if you could get the exhaust manifolds from a TTA or not.

 

i personaly understand a carb'd motor a LOT more than a fuel injected one,
so i would love to keep a carb set up
but if your looking for massive gains in a turbo set up you NEED fuel injection
with the 3.8L i got, when it was tuned properly and was running good, id say about 235-250 horses, and about 250-270 foot pounds of torque
(just a seat of your pants guess)
as far as swapping like a GN motor into a f body, you would need tta mounts, and possibly a set of custom made eaders, IF you couldnt get TTA set
assuming the stock GN headers wouldnt fit
now considering a STOCK motor can handle 125 hp shot of nitrous oxide, that would bump my hp up to around 300 or a bit more
if i were to add turbo to the 3.8L with all the old good stuff on it, and keep the compression where it is at, i would be able to make about a 15% to a 20% gain if i ran a pretty high boost 10-12 or so
so my gain would be roughly 30-40 hp
respectable?!

and my uncle who is a die hard monte fan and currently has a supercharged 84monte ss with a 327 wich has like EVERYTHING done to it, says keep the regal put the money into it blah blah blah
but the fact remains, i dont want to have to make a new interior, retune the motor, replace the transmission, install new rear end gears, get the new filler panels, repaint it AGAIN, and still be lacking the "look" factor of a fast car......
dont get me wrong here monte's cutlass's and regal's all have a NICE look to them, but it doesnt look like a 150 mph car......
camaro's sorta do
and those firebirds definatly do......
also is it just me or does the roof line on the firebirds look a bit differnt than a camaro?
the windsheild looks like its raked back a bit more.......
just me or is it realy like that?!

 

linuxguy,
drop the tiny turbo lol
the riviera one is STILL small, BUT there is a pretty good aftermarket for them , rebuild kits ect.
to do it, you would need to install a pulley wheel onto the turbo,
block off the exhaust in port,
weld up a mount for it (a/c bracket comes to mind)
get a belt for it
and possibly have to have it geared differntly
definatly worth the gains if you have a drill press and a good set of tools

 

Yes, I am going to drop the tiny turbo, it's just not big enough.
A turbo off of a Riviera you say? What years?
I am going to go back to the junkyard this weekend and look around some more.



Yup, already thought through all of that. The turbo will have to be spinning quite a bit faster than the engine - so it will have to be geared up (planetary gears would be nice) or use some sort of belt and pulley setup. The exhaust side of it will have to be removed so that it is just the shaft sticking out. When it comes down to modding the turbo, attaching all the gearing/pulley, mounts, etc...I have access to a machine shop for all of that. Only problem is finding a turbo that would be useable. If I can get a hold of a supercharger for a decent price, I am just going to go that route though.

 

The turbo-S/C option is a good one. Once I start geting money I have a nice little turbo that I am going to do it to. I am looking at a 1/3-1/4 drive system, where as the turbo will turn at 1/3-1/4 the speed of the crank. Simple math and gear ratio. If you do not feel like going through all that simply put on a BOV(Blow Off Valve) that is set to a certain level. Problem solved, and that way you can build the engine to take high PSI, but turn it down on the street like a normal turbo, then when racing turn it up.

 

What turbo are you planning on converting?
1/3 to 1/4 the speed of the crank?! That's slow. Turbos spin at around 100,000 RPM ya know. In order to get decent boost I would think it would have to spin at least half that speed...
That means a 1:10 ratio (engine spins 1 time, turbo spins 10 times, 10:1 if you look at it the opposite way) at 5000 RPM.
Sorry if I misunderstood anything in your post.

 

well i kinda test drove a 89 chevy s-10 blazer today......
4.3L 4x4 two door all options plus some
very nice ride,
mmmm
lit the tires up and made that whaling sound only a set of mud terain tires can!
very cool
probably going to use the camaro towards a trade on that since the dealer told me hed give me 1200 for the camaro and the blazer is a mere 1950
soooooooo........
:>
not gunna be a f-body owner for long,
but relax
im still with ya and am going to convert the ole regal to turbo so i can be of SOME use on here

 

Yeah i got the number reversed...I have a KKK .o6 Ex .08 intake
