But thats what you get when you try to make 500 hp on 2L or less. I love having an easy 350 hp out of 2L but its hard to compete with displacement.
exactly.

this is why a ITR trans on an LS engine makes it so much faster without even adding horsepower.

My ideal street car (honda) would be a 300whp GT2871R .86 with a ITR trans and LS fifth gear (for cruising)

Short gears is a MUST for NA cars (faster into the powerband, and when you shift, you fall back into the meat of your powerband aka rev drop) and most sub 300whp cars the short gearing is great. It makes the car feel so much more responsive.

It used to be that people thought the LS tranny was supreme for turbo setups, but now, everyone universally agrees the GSR is the best all around tranny. The LS tranny was just too long geared, and too much rpm drop in between shifts, and just too tall.

Heavier cars will want a shorter geared tranny, lighter cars can get away with longer gears.

It really all comes down to shift points, powerband, setup, displacement and rev limiter.

You can have a long geared trans if you rev to the moon.
