Hey folks,

It's starting to look like we have a few HP increasing options available from the aftermarket. And more than a few of you are getting these mods dyno tested.
Examples are the TOG header, K&N intake, PSI blower mods, Cat Back mods etc. Even the torque braces are offering performance improvement, even if it's not HP related.

I think it would be good to have a central location that explains the modification, accompanied with the dyno proven gains...or losses if that's tha case.

It will make it simpler to see what works and what doesn't..work as well.

The suppliers can get in on the parade too.

So how about it?
Would love to see combinations of mods especially.......

Ron

Excellent idea !!!


Peace :eek:

I am from winnipeg canada and nobody here seems to have anything but stock and no ideas

No offence guys... but long before you need a repository of information on how to increase hp, you need to establish a concrete way to put the power you have already to the ground. You've got a good starting platform and starting whp, yet the times aren't what they should be for the power in my opinion.

I'll give you an example. In RSX land, we found out over time that an intake manifold gasket and bypassing the throttle body coolant greatly reduced heat soak and kept the car from going limpy after 10-15 minutes of use. We also determined that different motormounts (energy suspension motor mount inserts or new enjo mounts) dramatically increased the ability to launch / put the power down. Also we found that there was a LOT of time to be made up with mainly midrange power -- with an engine tune I got arouns 20 whp in the *MID* section of my rpm band -- yet peak was far less of an increase -- note that time directly relates to power over time and power over time is area under the curve so don't concentrate on the peak number, which with a S/C, the cobalt ss should be a perfect platform to have fatty midsection growth with the right mods/tune. Also many of us on the rsx side just got sticker tires for our (02-04) 16x6.5 16 pound alloy wheels from the factory, others got rota slipstreams (13 pound 16 inch wheels) -- you guys have 18s from the factory -- get rid of those mofos asap! Also with the rsx we found that the shorty intakes actually LOSS power over the factory intake due to heat soak after a while, making a CAI almost a requirement unless you were turbocharged.

I'm just saying -- instead of focusing on peak power gains and performance (in the sense of motor), focus first on applying the power. You guys have a pretty impressive platform to work with stock.

One problem with increasing power a little bit is the inability to tune. The only thing that adresses this problem is the PSI-Fi kit, which uses the piggy back to help tuning with the addition of the pully. Getting our power to the ground and improving our times isn't as easy as other cars, because one of our biggest problem is gearing. The way the car is geared, and with the blower, 1st gear basically doesn't exist. There's either too much spin with the power, or launching too low to avoid that spin. We're supposedly geared perfectly for a turbo, but instead have the blower, so it makes things a little more complicated on the 1320. Put us on a road course though, and our cars kick ASS stock. The focus on makign our car was to design an overall performer, not just a straight line beast.

My first gear is basically worthless too... I have to 'sorta launch' then short shift into second and hold on or first simply goes straight to 8k instantly as the tires smoke away.

In regards to tuning -- why can't you use something like greddy emanage -- I mean I know it says for *japanese* ecus but... ignition and fuel is the same electrical concept right?. It would be neat to know if emanage would work for you guys.

just to let you guys know i have had the 3.0" pulley on for a week now and not problems with the car at all. Everything is handling great. wont have a chance to dyno it until next month but as soon as i do i will post some numbers. i also have a dynomax muffler to replace the stock one.

The reason I'm interested in the concept of this thread is that it's not just HP gains, its HP / performance gains. I want to hear about torque braces and motor mount setups here too. And I know we've got some guys that have already begun addressing the traction issues on here, so I want to know what's working and what's a gimmick.

I absolutely agree that this thing needs to handle the power it's got first and foremost, and the way I was spinning through first the last time I went to the track is proof that it is NOT capable of handling that power as-is.

I'll get us rolling with the mods I have planned and I'll keep up with this thread as I complete them to let y'all know how they turn out:

Torque braces
tighter springs
15-17" lightweight rims preferably on BFG rubber (well, for street use- Hoosiers on 15's for track nights)

These are the things I want to do before I even touch that blower, cause more power on the stock setup will either mow the clutch or the tires and still won't realize it's potential until the above mentioned mods are in place.

So c'mon guys, let's get the ideas rolling.

Well, I've got the BFG KDW II's, and the IronMan (formerly GoofyGuy) Torque brace, and have noticed vastly improved grip in first gear for launching a little easier. I haven't made it a habbit of launching at high rpm's and trying to practice, I just have done it a couple times. The brace helps with engine movement quite a bit, and the BFG's are a vast improvement over the stock rubber. Only have the K&N under the hood, but the TOG header is on its way as well. I believe those two mods are the best for the stock car as of now, then start gettin stuff for more HP/TQ.
