Sh0velMan - Who's dyno do you recommend we all use to get the most accurate results? So far you are not a fan of Specialty Z or Z1 as you have stated their equipment show inflated numbers.

Without an initial baseline run the final HP and TQ numbers are useless. Every dyno in the world will give different numbers on different days under different conditions. A car claiming 320hp and 260tq could actually be making less power than a car claiming lower numbers.

So many people seem to get hung up on these dyno numbers. Track and 1/4 mile times are the only real measures of whether you have actually made your car faster or not.

All of this.

It is my opinion that the Z1 dyno has about a 6-9% boost over most other dynos as far as the numbers reported on cars with near identical mods and conditions.

I have some stats I've collected over the last year that lead me to believe that there are some very real, very specific, horsepower limits without changes to certain key components which are basically never touched in bolt on builds.

So either Z1s dyno has some calibration creep, Z1 has access to tuning resources that other shops don't (meaning features of Uprev that aren't public and lead to huge gains, which is very unlikely), or these users posting results have secret mods they aren't mentioning.

Just one man's opinion.

They use STD numbers which is 4% inflated. It may not seem like much, but take his numbers and take 4% off -- not so impressive now.

Still pretty impressive for the mods he has.

Honestly, with his mods, I would be expecting 299-305 tops. I guess with a stellar tune and good weather, you could see 308 (which is his number reduced by 4%).

Sounds closer to the numbers i would expect. Damn, just when i had convinced myself 3 bolt ons would give me 60hp

Most base/stock z's are at what 275-285? And nismos maybe 10-12 higher? Thats a GIANT leap to 320 with a couple minor breathing mods. Hell i wanna meet this tuner, he must be some kind of ancient car god sent to earth or something.

I agree -- it's good for what he has, but we all know that the next mod won't give him that much HP. Hell, I dyno-ed 301 w/ G3's and FI -- I thought for sure I was going to hit 315 SAE w/ ARTs and tune. I ended up w/ 306 - 308.

My car was heatsoaked and it was 86 degrees out which didn't help. I'm going to install my oil cooler and go back to dyno tune so the tuner will have more time to adjust w/o worrying too much about heat.

edit: or F it all and go boost
