in search of more power.....can a mild 350 support turbos..with a little psi
 

i am searching for a little more performance out my motor ...i cant seem to break low 13's but i know it has it in hear...it is really stong mid way but not alot down low.....just looking to break low 13's maybe 12s can a mild motor support a turbo making small amounts of boost.....twins or single......not looking for a kit but a home built kit to stretch my fabbing ability......looking to get 500-600 rwhp...is this obtainable with a mild 350 non forged bottom end but all new parts?.......looking at maybe a cummins or some other diesel turbo to make a single but for a street car i heard the take alot of rpms to spool so i heard it is just better to go with twins......any help......liek i said i am not looking to break any lamd speed records just a little performance..... whatscha think

Yes but be prepared to break stuff. If a little boost is good, more is better, and it's sure easy to turn it up. I had an all cast internal twin HY-35'd 327 in my 67 Chevelle. I think those turbos were a bit large for my application but it would start making boost around 2500 if I just stepped into it from idle. I broke the ring land off the number five piston after about a year running 7psi, but It was an old motor. The engine builders on this site will probalby cringe, but used forged 350 pistons are cheap on ebay. I have a single hx-35 making 12psi on a injected 302 with forged pistons, stock crank and rods. I blew the head gaskets once, but replaced them with better ones and installed ARP bolts. I currently run 12psi on the street. It spools almost instantly. I highly recommend EFI for helping a turbo motor survive.

turbos
 

so in reality there is no insurance ....it may or may not support it... i want to build a boost ready motor but funds dont allow right now being 19 and in college....even a small single turbo my motor wouldnt withstand...

little more uh
 

do you know that your motor now is probaly only 300 rwhp?? and you think alittle more is to double it?? good luck, i would throw a 100-150 nitrous shot onit and call it a day

I second the nitrous shot
 

You can get an adjustable plate system for $400. Run that and start aquiring parts for the turbo set up.

It's hard to say for certain what your motor will withstand. I don't have a lot of experience and the guys on this site with the experience probably run all forged internals on all their motors. Check the jyturbo site.

turbos
 

i would have to disagree i knowi have no monster but my motor is making a little more power than that even before the rebuild and headwork

either way
 

that thing will blow up, if you try to double the power.
and a 350 with a 268 cam and some cast iron heads, is not going to be 400 rwhp, which would be 475 crank hp or so.
goodluck, but i would throw some nos on it and slowly pick forged parts on racingjunk and ebay then do the turbos

turbos
 

thanks ..i wasnt saying that i knew what kinda power i could get out thats why i was asking i had no idea just twnated to get some knowkedge.....i thought nos was harder on a motor than boost....so a mile motor can handle 100 shot

nos
 

yes, i think 150 shot and under is safe on most stock type motors, plus it will be fairly cheap, look at the top shot set up or better yet a used plate set up, that will get you what you want.

more power
 

so what kind of system will i be looking at fogger, wet, dry....any kit specifically

600 RWHP will get you WELL into the 10s... I'm with the rest of them and say look into NOS, it will get you into the 12s fairly easy and save you a ton of time and money. :thumbsup: :thumbsup:

nitrous
 

i am uneducated when it comes to nitrous also...what kinda set up will i be loking at. i dont want to blow a new motor up..

I agree with the rest of these guys about going nitrous, a stock engine should be able to handle a 150 shot. I have seen more but you are risking it. Look at a plate system, it sits between the carb and intake, easy install. But you have to make sure your engine is tuned very well otherwise you will have problems but that goes with any power adder. I was also building an engine for turbo but it was just out of my price range so i went nitrous, but my engine isn't a mild build either.

a "dry" system would be a nitrous only shot, normally used on efi motors where the injectors "can" add extra fuel.

a "wet" system adds both nitrous and fuel, either by plate or by nozzles.

for your set up you want to run a plate system, a seperate elec fuel pump just for the nitrous fuel side, 150 shot "should" be fine on a cast motor as long as you have fuel to go with the NO2, dont forget to retard the timing.

nitrous
 

so i would need an elect fuel pump on top pf my mechanical.

Here is the nitrous kit you need. http://www.jegs.com/webapp/wcs/store...tegoryId=14689

Adding a turbo or turbos will probably hurt your motor and cost you a good bit of time and money. You should be able to safely run one of these nitrous kits as long as you follow the instructions, take 2 degrees of timing out for every 50 HP and tweak it from there, check the plugs for lean or fat conditions and either adjust the fuel pressure or timing up or down depending on what the electrodes look like. Easy cheesy.

check to see if you have a place near you for filling the nos tank they dont last long. the next cheapest item i think would be a small blower like the b&m 144 they make good power for what they are i used one on a stock motor for 8 yrs with no problems 7 psi of boost ran like a mild big block.

Nos
 

thanks guys iwill look into it...got to see how my money pans out and i will go from there..
