That's sort of what I was thinking. 750-800, I don't think I will ever need larger. I

 

i don't think you'll need 720's on this turbo if you're runnin alky though.

 

Tym said 660s are ok.

 

If you're upgrading, why not go bigger anyway? I'd prefer a larger cushion. As long as you can control the dead time either w/ a flash or EMS, driveability should be fine.

 

Larger injectors cause slow throttle response. Buy what you exactly need and don’t buy 750CC thinking that you need room for later (that does not make sense).

660 for this turbo should be more than enough.

 

I have 1000cc injectors and my throttle response is lightning fast, so I think Tym said 660 as a this will work fine, not that 720-750 will not work.

 

650/660 should be good huh? Especially with alky. Cheaper

 

if your going to use a safc get the 720s so you can get a nice timing advance.

 

Umm then you shouldnt be driving an EVO.. go get an LS1 or a Cobra

 

What I have said above is not my experience only. It’s many years of experience on the track for people who been doing this forever. Trust me for a daily driver you wont feel it because your feelings are num towards your EVO. However, once you put the power you are making to the ground you will feel everything.

Why do you have 1000cc by the way? bigger turbo?

 

larger injectors aren't gonna slow you throttle response down! you can tune the throttle tip in accel or whatever it's called. most people with alot of bolt-ons are running the stockers at there limit. say this turbo can produce another 50whp thats at least 15% more fuel! stepping up to a 650-660 is netting you around 18% more injector. now if this turbo makes any more power you just wasted you time and money buying 650's. I'm running the stocker with 280's on an ems and i'm hitting 100%+ duty cycle. i'm limited to 19psi(11.5afr) and 7k rpm limit cuz my injectors are done. I guess it would suck to have someone flyout to tune your car and you find out you can't fully tune your car cuz someone on evom told you that 660's would work! I think the 720's are the ticket for the guy with all the bolt ons. just my opinion, nick.

 

680-720cc's imo

 

We all have opinions, and we have to weigh them. I need to get a reading on duty cycle. I wish I could figure out my test equipment and see if it gives duty cycle for the injectors. That would help

 

This is all true. I have used Robert's fierce bunny turbos in my own shop race car for past 3 month's, and also another EVO that I drove/set-up racing in the Caribbean. In my EVO driven by SCCA rookie Kent Jordan we have won 5 SCCA ITE races, 1 at Buttonwillow Raceway http://www.buttonwillowraceway.com/ and the last 4 in a row at Thunderhill, http://www.thunderhill.com/ At every track I have run with this turbo, we have gained a substantial amount of laptime when compared to the stock 03 turbo with the 10.5 hotside. The tracks we are talking about are Laguna Seca, Thunderhill, Buttonwillow, Ponce Puerto Rico and the Streets of Willow Springs. Each of these tracks require having excellent boost response to make good laptimes, and the white rabbit is an excellent way to go for both the power and reliability of this unit. All of our events are 30 minute races(in as much as 90 degree heat so far this year) which in the case of Thunderhill, we are averaging over 83 mph for the entire 30 minutes. For a street/track day car, buy one or for sure you will get passed by one. The added ultra bonus round about the bunny turbo is the ability to make good power that is invisible to the naked eye, as it is common here in Southern California to have local law enforcement wanting to inspect under the hood of rowdy biggee turbo EVOs.

Just ordered the 680cc injectors from Buscher. Good price and great service!
