cp-e "Standback" equipped SPEED3 made *ALMOST* 300hp to the wheels!!

[www.cp-e.com]

That is true on a stock MS3 with the older ECU firmware. To avoid getting into a long discussion about this, I could make one suggestion: Try running that graph on the 297 HP car and I promise you it would look nothing like that.

I'm glad you brought that up. I actually have a datalog from our SPEED3 when we were initially testing our intake and turboback exhaust. We made somewhere around 280whp (I can't recall the exact number) and the throttle did the same thing. Here is a graph of the throttle position versus rpm for one of the dyno runs:

You can see that despite making ~280whp, the throttle still tries to restrict engine output.

Methinks you got that one a little bit backwards.
In your previous example of how the throttle is closed (or open) 50%, it's not like the turbo is running at full song and the throttle plate is restricting the boost. Think about what it is that causes the turbo to spin faster or slower. Yes, it's the throttle (plate). It doesn't matter if it's drive by wire or not. More air in to the air pump, more hot exhaust gases out which causes the turbine to... ah, you know the rest.

You should drive the 297 HP MS3 and tell me if you have a frown on your face (because of the throttle plate) while it's smoking the tires in the first 3 gears. For most people, that is the bottom line. I find it very hard to believe that this car could make significantly more power and do it safely with the stock mini-turbo.

I would like to ask you as to where you draw the line with the stock turbo (keywords: efficiency, overspinning, seizure, meltdown). I'm sure you can easily imagine an over-zealous enthusiast trying to boost 15 PSI @ 6500 RPM. That scenario sounds like a recipe for disaster.

BTW, I think that you make fine products but someone has to ask the tough questions, right?

This isn't about "How much is enough," because certainly a ~300whp SPEED3 is going to a lot more fun to drive than my Geo Prizm! The point is that many people out there wish to push the limits on these cars, and we're going to do whatever we can to help them achieve that goal.

As far as melting the turbo, you really just need to keep an eye on your exhaust gas temperature. I wish I could give you some explicit parameters to try, but we haven't had much time to experiment with the car and probe its limits. So the best advice I can offer would be to invest in a good EGT gauge, wideband, and a good engine controller and find out. But if you do, you have to let us know what you've found

And I absolutely encourage people to ask questions! If we have data to provide, or have some experience to share, then I'll be happy to discuss anything SPEED3/6 related. So please don't think that you're "bothering me" with your questions!

what will the pnp second gen system cost?

what will the pnp second gen system cost?

I can't really say unfortunately, since we don't have the 2nd-gen hardware layout completed yet, and we haven't assembled a sample PnP connector, so we don't know how much labor to charge yet. But I would imagine that the next generation will be $100-$200 more expensive because the updated electronics are quite literally state of the art, and the PnP option will probably be another $200 depending on the labor involved in installing the wires into the connectors. I'm sure we'll have a much better idea of the final price in the near future as the project progresses.

how much is the current system so i can add it up and get a estimate..so i can save up ya know

$635 list per Street Unit's MS6 page.

Ohhh man!... (nailbyt) I wasn't thinking of getting the cp-e piggyback until I started reading this thread.
But I got a Q, Does the speed6 ecu controls the throttle the same way?, if not I wonder if we can swap ecus? (uhm)

 

[udontknowjack]

wow...thats right up in xede price.....(boom06)

hey jack, I see you have falken rt615's on yours and I am also frequenting the track with mine,

this is unrelated but how do you like them so far?

love them!!! first set is about to retired....alrite have a new/bigger set of falken RT615 waiting in the garage....(2thumbs)

u cant beat the price/performance...$137 plus shipping for 235/40/18
but if 1 have money to burn....i want to try yoko's ADVAN Neova AD07... most evo/sti guys used them in autoX....BUT they are double the prices of falken..(boom06) !!!!...i'll stick with falken RT615 for now....

 

[sixerjdm]

Yeah they seem outrageously reasonable and at my last track event an Evo 9 had them and he was caining everybody. I'm gonna order up, hope the back order isnt to bad.

i had a srt4 come into my shop that had an ems that adjusted the engine to the different octane rated gasoline the guy put in. if he put in 87 octane it tuned itself down to accommodate to the change. on 110 octane it tuned it up putting over 450 hp to the wheels. i'm still new to the computer tuning but was impressed.

Thats what knock sensors are for. You can pull or add timing to within a limit.
