That is a monster turbo. What is lag like with it? It must slam really hard once it hit though.

 

Yes it is but I cant say yet , I havnt tuned yet ........I do think it was very responsive in its last configuration though , I ran a 1.28 a/r rear end now I'm down to 1.0 and a GTX compressor so we'll see!

 

Sweet build!!!....cant wait to see it run

 

Insane work ethic and knowledge as well as attention to detail.....very well done Trini . We need to talk real soon on some advice on my project. Damn I which I was back home to build my FD!!!

 

Just for info and a warning ! DONT EVER BUY INJECTORS FROM FIVE O MOTORSPORTS !!!

 

Small update , I am having some problems with the tune , ECU or the fuel system , I cannot pinpoint it yet !The motor will start fine and idle around 13.6afr then it begins to lean out progressively until it stalls , sometimes it idles ok but when I hit the gas it goes wayyy lean (20+) which also causes it to stall or not move at all ! so far I have changed injectors , re-plumbed the FPR , checked fuel pressures to and from the motor , removed the internals of the check valves ,checked voltages at thw pumps, turn off all limiters and compensations in the ECU and still nothing !! I am stomped right now.

 

Kinda sounds like when the injector driver on my Haltech was going out.

 

I think that might be the case with my ViPEC too !!! when I stage the secondary injectors earlier (in vacuum @800rpm) the motor stays running and allows me to actually drive it! sooooo will be removing the ECU to do a last verification test in another car , if it does the same thing it will be going back for repairs .

 

Great job. That is some nice pipe work. I envy your skills.

 

Thanks bud!

 

lookin good

 

Any more updates. Or are you on another forum where u post more?

 

what p/s pulley do you have?

 

What's going on with the project Marcel? I'm impressed by the level of detail and the fabrication skills shown here.

 

Very impressive work and great documentation. It's lone-wolf kind-of-work, so satisfaction will come from a job well done (and done one day). Still at it?

 

Great work, pp engine looks pure power !

 

Waiting for an update on the status, dyno tune & feedback on the response of that monster GTX4508! Bet you are out enjoying that beast, hope all is well. Really great build so far!

 

Hi all ! after a long hiatus I am finally back!!!! I've been pre-occupied with work and building a new home for my family ,now that that's done I am getting back into the FD. I am still experiencing the same "lean out" issue which is now preventing the engine from idling for longer than 5 seconds at a time! I/we did some re-wiring , checked over the fuel system completely , checked the ECU and software and all functioned perfectly which suggests that the problem is actually unique to the car.It still definitely is a fuel delivery issue but it still appears to be electrically based so we are still looking in that area. The next phase planned is a complete re-wire using two brand new A/B harnesses .

 

Glad to see you're back on the forum! Been looking forward to an update on the FD monster.

 

I like! Nice work so far

 

marcel, i PMed you about your stalling issue, i believe i had the exact same thing on the same ECU.
Brad.

 

Replied.

 

sent you a more detailed pm mate see if that helps any!

Brad.

 

Any update on the build?

 

Seems to be a timing issue , I got it started a couple times since but it still isn't sorted yet, during my checks I came across an anomalie with the rotary engines and the ViPec system. The parameter known as the trigger angle , which is used to set the timing during the trigger calibration procedure varies greatly from engine to engine ! mine is set at 10 , my buddies at 24 and the plug and play maps supplied by them vary from -6 to -8 ! this just seems odd because TDC and -20 ATD is at the same place on the e shaft / FD front pulley assembly .
