Bang per buck, take a look at the LMS and Fujita intakes available. You can spend upwards of $200+ for maybe 5hp over a stock 259hp dyno is about a .019 or 2% gain!

So basically around $200 for each 2% gain on this car. This supercharger kit that nets approx 50hp and at $200 per 2% gain to total the claimed 50hp increase in power = $5000 bucks.
Unfortunately, we don't have very reliable baseline data to support that 20% claim. I also have a hard time believing that the resulting dyno data on a Mustang dyno would have been higher than the Dinojet data. It seems suspicious to me. I don't doubt that gains exist, but the data seems fishy. I also believe that SRI's make for poor comparisons, cinsidering the JoeZ intake is half the price, and AT LEAST as effective.

On top of that, an SC has much more impact on the car's warranty than I/H/E mods.

It also bugs me a bit that we aren't seeing how mid-range power is impacted. Peak numbers are fun to talk about, and probably apropriate for most I/H/E mods, but not for something that changes the character of an engine as much as an SC. I want to see how much may be lost down low. I imagine that the SC could be costing power (and significant fuel) at a 60 MPH cruise in 6th gear.

C'mon Gern. Haven't you seen the debate on whether dyno info in the lower rpms (below 4x00 rpms, where you have to worry about downshifting) is accurate or not?

Haven't you seen that the tranny can be locked in 4th gear by pulling a connector?

I agree. Is the juice worth the squeeze?

I don't think this has been tried yet, but from what I heard it may cause the engine and/or tranny to go into limp mode.

Sure. My post was clearly (perhaps?) in fun.

In deference to rt's post, I suggest we drop it in this thread.

I can see it possibly putting the engine in limp mode, but not the tranny. What would the "limp" be in a tranny that is locked in 4th gear? Even still, it is a diagnostic tool specified by Toyota, and I don't see why Toyota would want to limit the ability to diagnose something by automatically putting the engine in limp mode. We won't know until it is tried, but it certainly seems worth a look.

Departing from the argument now ...

Isn't there a general rule about percentage change in power based on each PSI of boost? I realize that some engines will respond differently depending on design, but it would still be nice to know how close this engine responds to boost compared to that ideal. I may be wrong, but I wouldn't expect an engine to benefit less from FI just because it has high compression. I would expect it to just tolerate less boost before grenading from detonation.

Damn. A company works on a completely new product for our cars and that yields pages upon pages of *****ing and whining?!

Why don't you wait until he gets the correct pully on the car and then he can post #'s with the original baseline data? Wow, that would be an idea [/sarcasm]

I am excited about this possability. I would really like to have a S/C on my car if it put me in the ~350+ rwhp range. I will wait on the new numbers and hope for me attention in this area from more companies (crosses fingers).

As lobux stated, the high compression is what's keeping the potential down.
Whoa, what kit costs $5000 that pumps out ~400 rwhp on a G35?
