Ive been on here for a while but havent made many posts, i can usually find an answer to a question but this time i was wondering if anyone had run a stage 1 head from zpi, trd supercharger, zpi 9 lb, 550cc injectors and greddy emanage for a tune?

im thinking of going this route because turbo kits, plus install, dyno, emanage and tune would run almost 7000 dollars and a supercharger with big injectors on a stage 1 head with emanage i could run for about 4500 - 5000 and hopefully getting about 230-250 whp

anyone thoughts are greately appreciated

thanks in advance, brian

 

I was under the impression that the upgreaded heads were for safety, but did not actually increase power.
Also, other guys with JUST the SC and 9lb pully arent' makeing 230whp, but I've heard that the stock ECU reflash is really inadequate, so you can pull another 25hp or so just by getting some management, like the emanage.
That SHOULD put you at about 225.

 

but hes asking how much mroe power he will make since w/ the stage 1 head u can increase the redline. That would make hte 9 lb pulley do more boost.

I would suggest keeping stock pulley w/ the stage 1 head and get a boost gauge to see what it finishes at. That will give a general idea of how much teh boost goes up. If u exceed 10 id suggest getting water/meth.

 

If you are willing to spend $4500-$5000 for 230-250whp with a supercharger because turbo's are too expensive, your money could be spent about a million better ways, like a turbo kit. ZPI stage 0 for around $2k, and you've got your 240hp, and you would have about another $2500 to play with. Thats just my $.02, though, do what you will

 

theres not a single bolt on ZPI stage 0 kit that has dyno'd at 240 hp in the world. There 230whp that they advertise as right out of the box is a far cry also. It seems like he doesnt wanna do things half azz'd so Id say the stage 0 is out of the question right of the bat.

 

i think it's very possible for you to hit 230-250whp even without the head upgrade or 550cc injectors, esp. if you are a 5spd. the 440cc that come with the s/c are able to deliver enough fuel for the extra boost. since you plan on tuning (i'd recommend the eman. ultimat, not the blue), add i/h/e, NST 9.5psi pulley (it costs less and you'll be getting a little more boost out of it too), forge 007 bpv and i think that'll get you to your goal.

 

You can get a little out of the midrange by tuning but for the most part only the people with water/meth have pulled decent gains. I'd really recommend trying to contact another person on these boards that has a turbo and see it in person. I was lucky enough to run against my friends turbo tC while I was s/c, learned first hand just how different they are (even @ 9.5 psi s/c'd). If you do the s/c do it for the right reason: money and the warranty.

 

from his post, it looks like he's more worried about money. but you're exactly right Rob, 230whp s/c'd will not yield same times as 230whp turbo'd.

 

I was always a person to do extensive searching and research before purchasing anything, through most of my searches correct me if I am wrong but isnt a turbo a better bang for the buck. I never even considered buying the s/c because of what I read. I personally would look through all the turbo info before settling just my oinion though

 

turbo is best bang for the bucks for most street 4 cyl cars. i think if white tc do stage 1 head with sc, full exhaust,9.5psi and tuned should see 240-260whp aprox.. right now im at 250whp with bolt ons and tuned.. so i dont see y not u make over 240whp head job gives more hp then a better intake and exhaust...

 

what i was thinking was the stage 1 head putting out 21 horse, or thats what its advertised at do to the polished ports and running more rich, the supercharge with a pulley and i have full line exhaust i was just thinking a new header, my car would be a hell of alot safer, it would be a good every day driver, and with the 2000 - 3000 id save could go to engine torque damper, stage 2 clutch, carbonfiber hood and trunk and still have money for a tune

 

if thats not enough to put me at mid to low 14's then its a lost cause and will just turbo the car

 

My friends best times (bought the s/c off me), ran 14.8's all day at the track with a 9.5psi pulley, full exhaust, and drag radials (not slicks). With a good driver you may get down to 14.5 with a good tune, but that would require the purchase of a computer. And to be honest with you, I don't like the idea of piggy backing a s/c because the boost isn't throttle dependent and will always run on the stock tune unless you punch it. Like I said before, if you're going to boost for performance go turbo. The midrange of a s/c isn't going to help you down the track as much as a turbo will. I think my car is pulling 200whp at 3500rpms or so (I don't have the dyno in front of me so please don't quote me). If you want a quick car that will retain your warrenty by all mean the s/c.

 

if you really want to stay with the sc,this is what i would do...9.5 pulley,cai/not sri,meth/water injection,all the little bolt on's,and full exhaust.that should put you close to 250whp,not require any aditional tuning,and run 13's with SLICKS. right?

 

Not 1 SC has seen 13's..

 

not even with slicks?

 

No. Although IceNine might have broken into 13's with traction, but he's also pushing more boost with cams, tuning, water/meth.... The power curve is impressive but still lacks a lot of midrange, spikes after 5k rpms.

 

are 13's possible if i had stage 1 head, ripp cams supercharged with a 9.5 pulley, header, full line exhaust and emanage ultimate with an aggressive tune and some good driving?

im not one of those kids that like to try something different i just dont have 6500 at one time to dump on turbo and all the goodies needed, atleast with supercharge i could keep that stock for a few months and slowly upgrade it to get about 260 whp, but if i cant get matching torque numbers than the car will never see 13's

 

its deffinately possible, but you'll need some good tires and suspension work.

 

You could do that if you started with a ZPI Stage 0. then slowly get more parts for it and you'll be at 230 off the bat.

I got my low end Turbo Toyotas kit for under 4K with injectors. It's been running without management for a week or so now cause I haven't been able to get to the tuners yet. then you would need gauges, but I would not wait to long on management.

How much do you have to drop on it up front?
