On the NA cars that aren't fully modded, the tune is pretty unnoticeable, even with all the mods, they are somewhat different.

For the FI guys the tune makes a night to day difference, especially in the turbos.

True. There's really not much to gain on unboosted setups. I remember reading on Trifecta's site that they only managed 10hp on their 2.2. You can get better numbers for sure, but don't expect to even see 200hp.

I have the SC model with cat-back and CAI, hopefully I will get something out of it then. Thank you for the info.

You would. Best you hold out on the tune until you've maxed your bolt ons and got a wideband. This way you'll get the most out of your tune and won't have to tune multiple times and waste money. Measure twice, cut once.

If it were my car, I'd upgrade to a TVS supercharger. It's got an extra 300ml of displacement and is supposedly more efficient. I'd like to recommend it, but I don't have any substantial experience or knowledge on FI stuff so it's best you get another opinion.

Turbo is better . If you have an lsj, get 80lb injectors, dual pass endplate, 2.8" pulley and hub, heat exchanger, option b reservoir and a tune. I would highly suggest finding someone that has hp tuners to street tune it rather than going through trifecta. Id also highly suggest getting meth

If you compare the efficiency maps from a TVS to an Eaton........lol.

Pulled from a Lotus site, since these guys use the M62 quite a bit.

Quote:
Now, look at the vertical lines going through the maps. That's the RPM of the blower. Forget the X axis for now showing flow...

The other numbers in the maps are the efficiency numbers... Long and short of it, is that you want to be as close to the dark bluw island as possible. That's where you should design your system to fall. Anything outside of that, and you may not have the right blower or setup for the application. I say "may", as you may not have any other option depending on the application...

M62:Recall that with a 3.0" pulley at 7500 rpms, the M62 is spinning about 13,250 rpms... At 1.7 bar (which is about what the 3.0 does pre IC), that's about 54% efficient... Note that at redline, of 8500, the M62 is spinning 15,000+rpms and is off the map... No where near the island in either case...

TVS: Recall that the 3.55" pulley creates about 1.7 bar (no IC pressure loss), the blower is spinning about 11,200rpms at 7500. That's right in the island and falls at 73 to 72% efficient... Not bad Right in line with Rob's 33% more efficient number... At 8500 redline, the blower is spinning 12,700 rpms. Still in the good color...

TVS at 14 psi or almost 2 bar... would turn about 12,000 RPMs would fall between 70 and 72% efficient. Notice how the TVS island goes so far north? if a fella wanted to really push it, this blower will stay quite efficient well past 15-16 psi even at the RPMs we turn...
Compare said pressure maps. Especially since you guys are turning nearly the same RPM's.





In a nutshell, for those that don't want to grasp it.

You're upgrading to a blower that is making the same power, if not more...by spinning LESS RPM's, creating less heat and parasitic loss on the driven accessory (ala, your engine), and has a much broader area to be efficient/make power IN.

If you're making the same power as a 3.0" M62 on a 3.5" TVS, think of what the 3.0" TVS will do...and you're taking 30+ percent less power of your motor, to make the same power, if not more.
