    That's what I have heard as well from auto journalists who have driven it.

    Re: "Tuning" the LSA?

    D3 will eventually release new products to address some of the pitfalls for the new 09 V. We have already started development of some new items and it should be pretty interesting when the vehicle is finally released to the public.

    With any blown vehicle the intercooler is always a concern. Since GM only builds these vehicle to meet their desired goals, you have to dig a little deeper to find the areas that need to be improved to increase performance and efficiency.

    One of the items on our hit list is very similar to what we have been doing for the XLR-V and the STS-V application with our plug and play module. This will not give you the "MOST" power possible through ECU tuning, but it will also not void your warranty. We have determined that most people would sacrifice a little bit of HP for a little more leeway with their warranty. Of course we will address those that have little disregard for the factory warranty .

    Thank you,

    I saw your car at SEMA but didn't see you guys... Did you have a booth that I missed?
    Look forward to the new developments!

    Re: "Tuning" the LSA?

    I am new to the forum, I had an 03 cobra. (the supercharged one) My family and I have outgrew it, so I am saving up for a new v. When my 03 was stock it was way rich, under 10:1 at redline on a dyno. It took an 9 inch CAI and full exhaust to get it close to 11.5:1. One of the big differences between the 03 and other ford FI engines was the internals were all forged. You could change pulleys, blowers ect and have no problems where the other engines would fail under the increased boost. 600 rwhp was not uncommon after a blower swap and fuel system upgrade. It was very popular to do this, while using a programer, then if issues were present, go back to stock form, and it couldn't be caught through the PCM. If you were to put a "chip" on the car, it would be obvious. I didn't do this, but I knew many who did. I am sure GM cars are drastically different, but I know you could with cobras. I just thought I would share.

    It would seem one of the better answers here is to do the oldest hot rodding trick. The first trick, enging swap. Void the warranty and then replace the TC or the clutch.

    This is what I eluded to near the beginning of this thread.

    If you are going to increase power, you have to have the supporting mods in place. To know what those are, you have to find the weak links in the system, which are almost always 1) cooling and 2) fuel delivery. My unsolicited advice with new performance cars is to let a shop like D3, Roush, etc. build a car and identify all of the weak spots for you. That is their business and it costs money.

    On top of the hp boost, you have the traction issue. Mustang Cobra's already come stock with more power than the wheels can handle, so your first mods are chassis, suspension, drivetrain, etc. Everyone loves to brag about hp and dyno race, but on the street a decent driver with a $400 set of rear nitto drag radials will beat a guy with $2000 of hp mods. Something to think about.

    Lastly, a tune if detected will blow your warranty if you hurt your motor. The dealer does not pay much attention unless it is a major motor issue, but that is of course the only time it matters. Simply reflashing the computer is NOT fool proof. The ECM has codes that show every time it is reset, and some other hints that field reps can identify to detect modifications prior to approving a very expensive warranty fix. So I'm not saying don't mod while under warranty, I'm just saying go big because blowing a $15k motor over a 20hp tune is a tough trade. At least trust your tuner and do not be ignorant about how the power is being made. Keep the A/F safe, and know what safe means for an LSA (back to D3, roush reference above).

    Florian's source is also my source I do believe.

    I was told by this source that there's a relatively easy 25% more power to be had with the LSA motor. I didn't press to get the details, but "700+" was the number mentioned to be attained on an engine dyno. I'm sure there'll be even more made by creative minds.

    I can almost guarantee you that 800hp could be made with this motor cheaper and safer than 600hp with the LS2. Boost is a great thing. No reason not to go big if you are going to do anything but cai/exhaust IMO.
