Let us see 3 back to back pulls on the street and then compare in virtual dyno. You likely will not be able to get repeatability like a real chassis dyno.

 

Same road and section you'll be surprised. I'll get some once I get my new aftercooler on

 

I have had very good results with virtual dyno myself. I got it tuned at 386 on a dynojet. Went out and did a virtual dyno...came back at 382 or so. It was very close.

 

Looks good to me being your at 18psi with E85. Should get another 50-60whp out of the 1200

How does the virtual dyno work and what software/device is used? Im unfamiliar with this.

 

You use it through aem

 

Wish i knew what a 450whp/500whp supercharged S2000 felt like. When i had my 350whp s2000 it still felt really slow. I was up on the fence between upgrading to the N1200 blower or going turbo. I decided that a turbo would make me satisfied. I still wonder sometimes if the N1200 around 500whp would of felt just as good. Haha.

 

There is a noticeable jump just from 350 to 400whp. 450+ is a thrill an a half! The stock NA power curve is fun, its just not enough of it for how heavy the car is as you know. But its fantastic when you literally double it everywhere in the rpm range with a 450+ sc. But it really comes down to what your expectations are going in. Some want the car to be heavy on bottom end trq so the car feels powerful when they put their foot in it at any rpm/gear, and some enjoy a power band that is top heavy where they get more enjoyment out of ringing the car out and driving it to get the most out of it etc. I really enjoy a top end power curve myself, where the faster you go the harder the car pulls, its just more fun. It also suited my road course driving style better.

 

Currently getting a bigger heat exchanger, parts should come in tomorrow! So hoping to see some
Lower iats!!! Maybe that means no more
Heat soaking!!!

 

Looking for 520/560 on 1200

 

I followed these instructions and got the most accurate readouts.

I am pulling my charger off today to send it off for the 1200 impeller upgrade. I will be running the 3.2" pulley on E85, but it should be close to what you are going after. I will report with dyno numbers when it is all said and done. I will be happy just to hit 500. Joey Butel hit around 510 with he 3.0" pulley on E85 way back when.
