Wholly crap I had a lower price for a one off set of forged pistons from another company (cant remember which one now). If I order them with coating on them they were still only $1100. Are these going to be coated as well, or just forged?

Oh, I could get cheaper pistons.....I just can't get these pistons cheaper. These are the LSI pistons....the cheaper ones are the L pistons....and we need all those LSI features.

Maybe that wasn't the best analogy. Before somebody asks no the pistons are not different for L's and LSI's. I was just saying the particular feature set we are using for these pistons is expensive.

I figured that was just an analogy, but part of my brain wanted to assign some meaning to it. I was thinking L = light and the LSI was Light Strong Indestructible or something

Everyone's piston orders are in with me and I actually put the piston order in a couple days ago.

It should be about 6 weeks till they are done. If anyone else decides they want pistons between now and then call me and I'll call them and see if we can't add to the batch.

sorry if i missed it but has any one dynoed an ecu-tune stage 3 svx yet, just looking for numbers thanks

Run a search and you will find the exact ##'s but here is what I remember
LAN on 12lb hit 270whp
Tom on 12lb hit 248whp (I think he needed a exhaust pretty bad at the time of the dyno)
Mike on 9lb hit 220ish i believe

I was hitting detonation at 12psi with my old motors

Not that there's anything wrong with a 70-100 whp increase but...

When you look up the old plots you will see we were hitting our torque peak all the way down at 3500 rpms and it looks like we were having problems clearing the exhaust out of the combustion chambers at rpms higher than that.

The expectation is that the cams we are developing will remove that bottleneck so that torque does not drop off until a much much higher rpm, in which case we will see much higher power levels.

We've also seen evidence of problems with blow by which we are overcoming with custom gas ported pistons which also have a lower compression ratio to allow higher manifold pressures and deeper valve reliefs to maintain zero interference with the larger cams.

Basically it's looking like you should really build an engine if you want to supercharge it--especially if you have a high mileage one. So far all the low mileage engines have done well and all the high mileage engines have not--probably because the rings are not as tight and just can't seal these kind of cyllinder pressures.

hopefully all these mods will be alive and kicking once I get some money in my bank account and my credit card paid off in full. I wet myself in anticipation about 3 times over the last hour while I was dreaming about a supercharger, and pistons, and a cam, and an exhaust, AND THEY'RE ALL GROUP ORDERS! damnitall.... why couldn't one company be like, "hey! theres a market for this stuff... maybe i should make a huge batch and then sell them out of a warehouse."

sorry guys i have to end my rant because i should really wash up.

sicksubie · #**1257** 03-15-2007, 07:38 AM

Not to dampen your spirits, but these are group orders because there is no where near enough of a market for these products. Also, you have a 1996 SVX. That means OBDII ECU. LAN's products are for the OBDI cars (1995 and older). I think he is working on or mayber even finished a stage 1 ecu for the OBDII people among us, but I think that is the only thing applicable to you at this point.

tommy96LSi · #**1258** 03-15-2007, 10:43 AM

theres always gotta be a first... I'm a little new so I didn't even look at the specs yet for all the mods. I look forward to having even that much more of an original car. Alright, I'm done hijacking, you can have your thread back.

sicksubie · #**1259** 03-15-2007, 02:11 PM

You will face more challenges, just dont get discouraged

longassname · #**1260** 03-16-2007, 10:15 AM

When the time comes and you are ready to build and engine and supercharge you can make an adaptor harness and install an obd1 ecu.

The plug off of an obdII ECU + the plugs off an obdI wiring harness + print outs of the ecu pinouts + a few hours at a table with a soldering iron = conversion to obd1 which can be plugged in without ever cutting a wire on your car and unplugged when you want to take it back off.
