BTW, can you send/post your g-Tech files? I'd like to have a few other cars to compare against -- I think you and I are pretty closely matched.

Must include hard data within your post. Something like this:
BTW, if you look close you can see I lifted before I got to the Qtr mile mark on runs 2 and 3.

Sorry I tought that the figures from an actual run were sufficient. I have the actuall time slip at home but not at work. Will take a picture and post it later on tonight. The time data from that run is accurate but to prove it, I will post the slip.

In all seriousness, that is an awesome looking dyno sheet, congratulations! I know you put a ton of effort into making that happen
![bowdown](https://rennlist.com/forums/graemlins/bowdown.gif)
Here is my best dyno sheet from about 3 years ago. This is from my 5spd car and I really haven't done anything to it since then. Based on the roughness of the curves and the power falling off up stairs you can see I'm having some issues. I'm hoping to get to it within the next month or so. Hopefully with a little tuning I can close some ground on you but those are some pretty lofty numbers.

So I guess your's is bigger than mine. But what was it that Dan said, you can hit both sides of the tuna can, just not the other end!

If we factor in cubic $ per hp, you are way ahead. Maybe....

I have a shelf in the basement filled with boxes of R&D parts and engine parts.
Mife wife asked me the other day; "what in the heck do you have in all those boxes?" I told her "religion".

I thought Dan was looking at you when he said that

600 rwhp is the goal for my 5 spd and yes I think it is very achievable.
My goal for my wifes car is 500 rwhp, which I also think is achievable. If I cannot get the car to 500 then I am going to **** can the Stage 3 project because in my opinion the cost and complexity to get the car past the 400 rwhp mark to only make an extra 50 rwhp isn't worth it.
Here is a Stage One Dyno

600 would be nice Tim. I'm sure you'll get there. Personally, I'd love to see 475. DR thinks it's there, just need to spend some quality time with a SharkTuner at a Dyno shop.
Here's a virtual drag rage between your ***** and mine (I got thoroughly spanked!)

Can you input just the raw 1/4 mile data and have the G-tech software run a simulated comparison against an actual G-tech run?

BTW (unrelated to the above), I just learned that when i dyno'd the car I had the guy hooking up the boost sensor to before the intercooler which will result in a reading .5 - .7 psi higher than actual boost. My datalog said I made 7.1psi which is probably more accurate.
