Nice! Is that the full stage 5 with the ported blower as well?

Nice # but i have a question

On that same dyno I made like 271whp and 258wtq

Cept I only had

K&N CAI
2.5"
60lbers
Rob's Tuning

I still had completely stock exhaust system and a stock UNported blower...was it the weather that day?

On that same dyno I made like 271whp and 258wtq
Weather conditions definitely make a difference. Even though we have all our dyno charts corrected to STD, ambient temperature, relative humidity and barometric pressure can easily account for 3 or 4 horsepower and/or foot-pounds of torque variance from day to day.

so when I ran with ya it was corrected?

I was just wondering cause he has lots of exhaust work compared to me when I dynoed

so when I ran with ya it was corrected?
Of course. Just look at your dyno chart. If it says 'STD', then the 'standard' correction factor was used.

Can't remember for sure. Sorry!

Ya I can understand the 3 or 4 hp from weather but I had completely stock exhaust system from header to tip where as he has header, high flow cat and cat back and a ported blower over me...thats was what i was wondering about...dont mean to sound like im bashing sorry if it comes out that way...sweet numbers either way.

I don't understand, on your site, the Sg 5 claims to give you 270 hp all by it's self. But all theses guys have many bolt ons along with the Sg 5 kit and not one of them have hit 270.
:wtf:

thats what I was wondering

Every motor is different and even the same mods on the year vehicles on the same day can produce different results on each car. Our kits have been proven to produce UP to specific HP ranges which we disclose on our site. This particular setup was within 2 hp of our best pulls with the stage 5 kit on pump gas.

As Scott stated, various environmental conditions can play a part in HP production. I'm sure you are all aware how much quick and stronger the car feels when its cold outside. If people want the best possible numbers from their setup then dyno when its 10 degrees outside on a clear day and put race fuel in the car. As this stands for a street tune its a nice setup with good safe power production.

One other thing...Maximum horsepower is not always the best gauge of how mods are performing. The shape of the curve along with power output over the entire range can prove a much quicker car even if two cars have the same or similiar maximum hp numbers.

It's at the track that numbers matter. :)
