Is there a way to increase torque from the supercharger other than not reflashing the ECU?

smaller pulley = higher boost.
intercooler maybe? I know that ZPI is working on that.

Unfortunately with centrifugal superchargers you sacrifice tq to make more power. This is due to boost threshold not occuring until redline. A smaller pulley would net you some extra power as you will hit more boost earlier in the power band but it intercoolers and smaller pullies wont get you turbo or roots blower style torque numbers.

People would just be adding stress to the motor redlining it in every gear just to eeck out the most boost lol.

more torque would be awesome with the SC.

so would a lsd

Get an emanage and up your rev limiter to 8600rpms, all the S/C dyno's I see just look like they continue to pull. Maybe those extra RPMS will give you a few more HP and FT LBS.

OutCrnrU 's dyno sheet for reference.

A nice water to air intercooler with a custom ice box setup should give you a nice gain.
And Smaller S/C pulley and Larger Crank pulley. That should put you where you want to be.

They continue to pull because you are increasing boost by overrevving the motor. The boost continues to build and as a result you get a little more tq and hp. Even with the watercooler dyno you posted look at the tq numbers. While 180s is not bad its not 260 ft/lb that a turbo will net. The upside to the centrifugal blower is that the power curve is as linear as it can get.

Depends how hardcore the S/C guys wanna get. A lot is possible.

We know a turbo is better. :| I just like the warrenty part...but it will go away once you add pullies and whatnot. So we cant win. lol

Tell me about it. At least you guys get a warranty ok'd kit to boost the car... If we boost the car at all we lose our warranty...but yeah I hear you. A lot is possible with a blower. I'm just a turbo-nut...LOL

^ I noticed...:lol: I love my DSM when it works... So i'd like to get the S/C and keep it reliable....

i talked to my tuner and dyno guy and says there is a lot of room to work with in the ecu. because of the refshlash the car runs pretty lean, tune the ecu to run optimum air/fuel ratio and you should see some good torque gains.

i just intalled the pulley tonight and i am impressed. once you hit 5 grand the car really pulls you into your seat, definately more high end torque and hp.

HTH

Lean? All of the charts I've seen (mine including) the AFR dips into 11s closer to redline - and that's the opposite of lean from my understanding.

With a rev limiter so low, I think it'll be ok. It's hard not to bounce the rev limiter.. I'm used to my Miata, fuel cut at 7300ish, valves float around 8.. :o

To a certain extent, lean would give you more power.. until you start detonating or melt the pistons..

I have to agree with zoltiz.. It's pretty rich at WOT. You loose some power from it, but it's a good safe tune.

How can I have the torque match the hp with the supercharger, similar to the 160hp 163tq from stock tc. I am aiming for 250whp and similar tq numbers

Who cares about tq numbers? You want a pretty dyno picture - there's photoshop for it ;)

Thing is, you'll never be able to match it.

Why?

Max torque happens at max boost. Max boost is at redline. Due to the HP formula, at 6000 rpms, HP will be 14% higher than torque, and that percentage only increases if you bring it to 6500.

If we had a roots-style charger, it'd be a different story. More TQ than HP. It's also possible to get more TQ than HP by using a smaller, low-spooling turbo.

would you e able to get a dyno now too with the pulley? :pray:

ZPI pulley showed 21whp / 10wtq on my car. So all in all I have about 46% gain over stock with SC/pulley/stock exhaust.

How much torque do people really want this days ? :nails: 180ft/lb is alot already! I have no plans of hualing a boat with more torque.

or are you looking for head jerking power once boost tops out ? Centrifugal dyno's are pretty :P

a lot of vic owners would kill for those torque numbers :P

180 is just about right for the tC. at 180 you can put some gummy tires on and not be too hard on your axles. Too much torque + some sticky tires = broken parts.

you will notice a big difference i u get a light flywheel and a ingalls etd. the etd helps u put aalll your torque to the ground instead of some torque without it. the flywheel will kick your power in sooner with the faster excel that it does. i hope somebody tries this.

I will tell you guys this. As long as there is no Quaife you may not want all these torque numbers. I am at 197ft-lbs and there is NO WAY I can full throttle in 1st gear...
OutCrnrU you need to get that thing dynoed now. I cant wait to see where you are at. You should have passed me with that addition, unless that S-Pipe is really that restrictive.. Cause as of now, you and I are both restricted at one point. Me at the header and you at the S-Pipe... hehehe..

i know i will try to get it dynoed again but its so expensive i cant make any promises... also i was gonna try to get the s-pipe before i dyno again, i believe the stock s-pipe is really holding me up right now, i will see what i can do in the next couple of weeks.

Aight man.. .take your time. I am hoping to get my header here in the next month.. CROSS FINGERS!!!!!

What about replacing the stock cams? N/A cams in a forced induction application is less than ideal, I would think.

if you could tell me where to get fi cams for the tc i would buy them tomorrow but to my knowledge nobody makes them yet

You should ask the Dezod guys about that. I thought they were working with crower or someone to produce FI application cams.
