What do you make of this device?

The D-Tronic module. Looks kinda like a MAF Translator for 3x the cost (but then again D3 is always ridiculously overpriced). No idea why anybody would go that route over a Trinity, but I'm kinda curious about it.

Dude, if their idea of 'optimal' AFR for a supercharged vehicle is 12.5:1, then thats the end of the story (and the end of that engine )

[mikel]

At least when I had a MAF translator, it had separate settings for idle and WOT...and cost about 1/4 of that price.

Thats why their cars, even running over 1,000hp, are still barely in the 10's. Can't tune worth a damn.

Bummer.

I see the local V (fastest in country, still stock blower) is apparently planning a whipple upgrade. Should be sick.

[Mike_Levy]

I was looking at going to a 4.2L Kenne Bell instead of messing with the Eaton, but dropping $11k on a blower is not anywhere near in my budget. I'm gonna try to make 1,000 with the stocker, then drive it down the coast to you guys so Johan can dyno tune it.

[mikel]

1000 with the stocker aint gonna happen

They seem to be done by 700 rwhp. beyond that you're just heating the air and pushing way past the blowers efficiency range.

Maybe look into a 2.3 TVS (ZR! blower) upgrade....

[Mike_Levy]

Looked at that. For the $7k it'd cost, I'd rather go twin screw. The blowers aren't interchangeable, according to Lingenfelter, so gotta go with a Magnuson kit to get the bigger blower.

I like this Stage 4 kit, but the cost and needing a new hood and everything kills it.

The 1.9 is good to about 21000rpm, or 17psi. So I'm thinking if I can make power in the motor, with heads, cam, etc, then I may be able to run 17psi and get big power with it.

[Mike_Levy]

Okay, well the guys at Lingenfelter are wrong I think. Just came from the Chevy dealer. There is absolutely no doubt whatsoever that the LS9 blower will bolt to the LSA. The intercooler is iffy (can always use the saddle one from the ZR1), and the lines and sensors are in different places, so its not gonna be a direct swap, but I see no reason why it won't work...... if the belt lines up. And of course the TB is in a different spot, so the intake would have to be custom.

Gonna start searching the Salvage yards to see if I can get one. Making harness extensions is easy enough, and rerouting the coolant lines is easy too. Hell, I have no problem playing guinea pig. I do it all the time.

I think there is a front drive difference....pulley wont likely line up out of the box.

[Mike_Levy]

The snout on the 2.3L is shorter so the drive should, theoretically, line up. If I measured it right, both are the same distance from the front of the head. The only difference is the 2.3 has a 10 rib drive and the 1.9 an 8 rib. So put on the 8 rib pulley, and it should be fine. And if not, just press the pulley on less or more.

I have a message in to GM Performance Parts, since they sell the 2.3 and intercooler as a kit (P/N 19244103). I'll see what they have to say.
