I have been thinking about going turbo for a while, but I keep overlooking the potential of my Vortech supercharger. I know that Tech2 makes a 9psi pulley, but I was wondering what the limits of the supercharger is. It says that the max impeller speed for the V-2 SQ SC-TRIM (which is what I have) is 53,000 rpm. How much boost would this be? Also, I think I read that 14psi is about the max. psi b/c of slippage problems. How much would it be for a custom pulley? I just want to see the price differnce if I juiced up my current setup opposed to going turbo/built engine. If I went with upgrading my current setup, I would probably get some head/port work done. Any help and input is greatly appreciated. Thanks!

I believe 14 psi is right. A custom pulley is only like 100 bucks. You will need fuel management though.

 

Right...at 14psi, I would need larger injectors right? What size?

 

14psi.... the size of the injectors depends on what you want to do.....

 

I want to make as close to 400whp as I can. I really don't know how much hp 14psi with good tunning would yield. I would search s2ki.com, but I haven't been able to access it for the past month or so. My list:

-Custom pulley and belt
-Injectors (size??)
-AEM EMS
-Comptech housing
-Alaniz Competition Headwork (including Titanium retainers, Bronze guides, and Inner spring/locator kit)
-Alaniz manifold work
-Godzilla BOV

Would I benefit at all from a Spearco radiator? What are the gains from 4.57 (would this be the right one?) gear be? Is it worth the $$?Also, I don't think I am going to need my engine bored, sleeved, etc for this setup. Anything to add or subtract to the list? Thanks!

 

well from my knowledge 400rwhp is as much as these paxton blowers will produce....

as for the gears.. it's not going to give you higher numbers it's just going to allow you to go though the gears faster....

there's a couple of people on s2ki. have have reaced around 380rwhp with these superchargers....

 

Yea, I don't really expect getting 400...in my mind I want about 350-380. How much do the gears help in acceleration? Would they be worth it for just street driving? Also, what range of other cars would I be in..you know, what could I beat?

 

Ive seen the over 350 mark also with S/C, but I dont think Ive seen anyone running over 11 psi. 14 is the absolute max boost the Vortech unit can put out. Whos to say if the unit can hold out running that high.

Your going to need at least 650cc to 750cc injectors and a reduction of compression to run that high of boost along with your AEM and some major tuning. Dont worry about gears until you have the engine setup.

 

Whos the guy on s2ki.com who has a vortech supercharger and runs higher boost? I think he was running at 11psi, and he said he was beating 360s, and other high end cars like that.

 

The guys is BS'ing. I'm assunimg you have a s/c now right? What is the real reason you want 400 hp?

 

Yea, I have a vortech supercharger, hks exhaust, dc headers, act 6 puck clutch, fidanza lightweight flywheel, and some other non-perofrmance realated goodies.
Why do I want 400hp?

1) I want more power, so I thought 350-400 would be a good goal if I keep my supercharger. If I went turbo however, I would buil my block and boost around 14-18 psi.

2) I want to compete with some high end cars that swarm my area. On the track or course

3) Did I say that I want more power?

4) I need more power.

 

Ok, have you had your car dynoed in current form? What type of cars and what type of track are you trying to compete on.

 

you might not what all that much power if you're on a road track....

and with 400rwhp.. you'll be able to hang with a lot of cars out there...

 

Nope, never had had my car dynoed. I figure I have about +- 300 to the wheels right now, but I plan on dynoing my car once the weather gets nicer. It's all snowy and crap right now...I need to drive the car soon or I am going to have a breakdown. Actually, when i said track, I was trying to make a smiley face with a wink. I don't plan on taking my car to the track (maybe once or twice for driving school) but I want to be able to compete on the street if I have to. My good friend is getting a C6 Corvette in April, so I guess my first target would be that. My neighbor and his 360 would be a nice lunch I guess, but I am not expecting to beat him. Anything from there on would be a bonus!

I dunno, I am just thinking to go to a turbo setup. What would you do?

-Matt

 

if you want to kill those.. go turbo hahahaha. get the inline kit.. and you'll be able to hang/beat them..

 

How long has InlinePRO been driving their s2k with 18psi? Do you really think that it would be safe running it that high with just a 3mm hhead gasket and ems? It scares me for some reason...I guess b/c alot of people have said it can't be done.

people are just idiots. hahahaha. they are scared of things they've never seen before....

as for the inline turbo.. they've been running the car like they stole it for around 10k miles now.. at 18psi.. however they are using a vafc......

now think about that.. but upgrade to something safer with an aem ems... complete tuning, and you can even lower the boost if you want... it's just awesome.... keep in mind the s2000 comes with forged pistons and rods.. so it's quite strong to begin with..

 

Do you have any idea how long it would take to tune with an aem ems? I need to find a place to get it tunned thats near me (St. Louis). Also, how much more power would head and manifold work from Alaniz Technologies free up?

 

i dunno.. that all depends.... tuning could take a long time.. or it could be really short..... if i was you i'd go out looking for someone that has the kit. and is willing to give you their tuning sheet... so you can copy it and work off of that....

as for the head and manifold work.. i dunno how much it would free up.. boosteds2k has a ported and polished head i believe.. but remember.. a lot of the stuff for our cars is really based on tuning.... the better the tuning the more power and the safer it can be.... tuning is number 1 on this car...

 

Yea, I will look for some more info, but I can't get into s2ki.com. I have no idea why it won't connect me to the site.

 

yeah i had that problem yesterday... i've gotten on today tho..

 

To compete with them youll have to go turbo. 400+ hp. Be ready to spend over 10gs to do this right. Do you have a second car, a tuned to that much HP will kill your everyday drivability.

Remember though, there is always someone faster.

it doesn't necessarily have to kill your daily driving..... yoiu can always get a two stage... or get a boost controler... so when you're daily driving drop to boost down to like 12psi or so.. around 350rwhp... and then when you're racing.. raise the boost to the 18psi.. for 450rwhp.. and have a go at it...

it's not like yoru supercharger, where you gotta pull out your pully and get your tools out.. and start working under the hood. to change the boost hehehehe...

turbo, push a little button. and you change the boost hehehe.

 

Yea, I actually have 3 other cars so that is not a problem. I really only drive my s on the weekends and on really nice days. I would definately get a boost controller for what you just said.

-InlinePRO turbo kit
-Head and manifold port/polish work
-Enlarge exhaust piping on my HKS to 3"
-Comptech reinforced diff. housing
-aem ems
-boost controller
-uego controller?
-wideband ?
-3 bar map sensor?
-larger injectors (the inline kit doesn't include them right?)
-install
-extensive tuning

I know that I am probably missing some things. What else? I have a boost gauge right now, are there any others that would be useful?

 

You know if your going to do all that, you might as well and not cheap out with a head gasket. Get low compression pistons and the rest of your block redone.

IMO, I have yet to see a turbo S run trouble free. If its not an idle problems, its a boost leak., etc...... Not to say that there are some out there running fine.
