I have been on the fence for years about doing a small shot (50-75). Besides Ari who else has run this untop of a turbo rotary on here? I want to know more on the tune (timing changes) also did you do a dry or wet shot. I was thinking a dry shot would work but was told by a certain guy the correct way was to run a wet shot (but his car doesnt even run right now) just kidding Ant..

I want to know the effect it had on the engine temps if any and if you need to pull timing.

 

I ran a 50 shot on my TII for a little while...very crude setup, nothing to base a build off of.

That didnt last very long. But it was user error.

 

done the right way, dry shot+extras... done the wrong way, wet shot...

75hp shot dry system, two nozzles as low in the manifold as you can get them.
window switched through the boost controller
WOT switch or use a full range TPS.
configure AUX output on the ecu for a grounded loop to alternate timing maps + fuel increment.
set it up however you see fit and fill in the details at your on discretion

no wet system, means no potential wet backfires

pull about 4-5* timing at peak TQ

 

Oops. I meant to say Anthony said a dry shot was the right way, not wet. Time for me to upgrade to real ecu. Thanks for the info.

 

LOL, don't save me! The setups that I have seen on a rotary were wet shots where the AF ratios were set by the size of the fuel and nitrous jets. I have seen friends run nitrous and they always went with the wet systems, not saying that's the way to do it since I never ran nitrous.

I would think if you had to run a dry shot and then have an ecu compensate to richen things up or some other way to fire up some more injectors and I wound be worried if there was a delay anywhere in the process and you go lean. I have seen dry systems for NA but for a turbo application I would go with a wet system if I had to do it. The guys with experience can tell you the right size fuel jet for the shot you are running. The first link below has the jet sizes for a wet system.

Don't forget your tuner (Ray) ran nitrous years ago on his 9sec pass, Judge Ito is a nitrous guru and as you already know Ari. Post what you find out.

put me first inline for all your "obsolete" parts!

 

Figured you would be going lsx ? I know you are a rotary guy at heart tho.

I will let you know if any parts are up for grabs. I ask allot of questions but seldom make the change.

 

am going with a wet system with 2 foggers 1 for each rotor
fresh rebuild street port with stock twins

my goal is high 10s on boost only and low 10s with nos will keep you posted on dyno # soon

 

From my research a wet shot is the way to go. I looked into running a 50shot on my tii block only problem was controlling the boost creep. Vex has a decent priced wet kit for turbos that has a boost switch for activation.
