Thought this might be a good idea to have a running thread for EVO owners' and potential buyers.

This would give us an opportunity to discuss problems, improvements, software updates, driving impressions, etc...

This would also be a great source of info for potential buyers.

Feel free to post pics, dyno charts, kills, etc...

There have already been improvements made that I'm sure owners' of the older kits are not even aware of (new oil return line, silicone boost hoses, brand new software upgrade).

I think this could prove to be a valuable resource as the kits get older and more kits make it to market.

Feel free to chime in if you have TPC, but I don't want to turn this into another TPC/EVO pissing match thread. We already have a "verus" thread going.

So if you have one, post up so we can get a count.

 

Check the AUTOWEEK magazine this week for a good article on a Modified C2. Maybe you can also look at it on www.autoweek.com but I am not sure.

deputy: I think that's a good idea if enough people are game. I'd like to know what some of the improvements are since I have kit #10.

I'm having fun building my own using the Vortech as the SC of choice. In the process of doing so I found many modifications which are useful if not, needed. Anyway here are some engine mods.

1. Temp sensitive fans upfront on the SC radiator (important in southwest where it is HOT!) still in development stage
2. Larger resevoir for closed loop system
3. Diverter valve - good choice is FORGE (slide type) this is if diaphram type is installed.
4. Oil drain line on SC, bendable but of all metal
5. Cool air brought in to the SC from outside engine compartment through tail foil - still in development.
6. Improved intercooler connector clamps
7. In-line crankcase vent filter back to inlet of SC

 

I'm too scared to talk

 

HA!

 

so there's only three of us on here with evo sc kits???

 

have any of you guys put your car on a dyno yet? curious to know what numbers you ended up with....

 

how is it driving or have you been able to take it out with all the bad weather down there?

 

haven't got it back yet. they had to tighten up a few more things before i could take it home. hope to have it back in a couple days.

 

I would love to get a software update so that d*** CEL would go away. I use my OBII program to reset the CEL and for 100 or so miles the car dies on decelleration while its learing about the lightweight flywheel, then after about 400 m the CEL comes on again. Now I just drive most of the time with it on. Todd gave me a new resister to try at my altitude but I feel that it was just a shot in the dark and I haven't tried it yet. I still would like to try a water spray in hot weather and see if it helps the intercooler work better. Will

 

Post pictures HAHA

 

Good seeing you and james yesterday.

 

Well, got the car back today. Impressive. We had a small glitch or two, but seems to be worked out. I appear to back at full boost and the car seems to be running very strong.

Other than a mild wine from the SC, you always can't tell it's there at low rpm/throttle. However, wind it up and you can really start to feel it pull. Much different than the TPC kit, but I think my wife will enjoy it much more so due to the fact that it's not "ON" all the time. The TPC kit made a lot more boost at low RPM's, but you also hear it running (and it's loud) all the time.

So far, I'm very pleased. No CEL's and it's running smooth (knock on wood). I have an appointment for a dyno run on Friday. This should be interesting. The weather has really cooled down here so that should be very helpful. Not to mention the dyno shop has five fans, so we're going to have one on each of the three radiators up front and two on the engine. Needless to say, it should be very breezy

 

I wonder if the fact that the EVO in not on at lower rpm's will mean less wear and tear on the engine in the long run. For instance, if you are not stepping on the throttle all the time (I usually do not when I drive - only when I really need to), the engine will get that same amount of pressure as a stock engine. Make sense?
