The car runs, they're still tunning though. Right? [/quote]

Thats the latest of Dragons news.Besides his DD FD. [/quote]

Not tuning anymore until he builds the ported motor, which should be in the next week. 16psi is the stopping point for now, no point in going higher, because there is no more power to be had on the stock block.

 

Gotcha, what are you guys shooting for power wise? 700?

 

i think he said 750, whether he will be able to keep it on the street or not i dont know. that would be the most impressive thing of all.

 

I think the problem is not the power they want....it's the power they can put down. I dont' think Chris wants to run Slicks to drive the 20B.



As a comparison ... Chris first got the 20B running... we went out driving so he could get his driving range down... I had to BOOST .2 kilos to keep up...and he was under vacuum the whole time. Lots of torque for a rotary....lots

 

Thats the torque of that third rotor for yah.750hp would be nice to take out on the weekends to the local strip all street legal.I wish I had some bling. Hey Dragon wanna donate your stock port 20B to me when your ported one is done??? I'll take good care of it. Are you street or bridge porting it?

 

I'm going to shoot for 700ish with a nice side port 233.3 hp per rotor shouldn't be too hard to come by.. Hell I have to fight the steering like this already, so the car should be pretty uncontolable the way I like it with 700 hp and tork for days. We have a race in 3 weeks, so i won't have time to put in the side ported engine and break it in and then tune it by the race, so I'm just going to put on a smaller ex housing so it'll boost faster and race it the way it is for now and then put the built engine in somtime around the new year.. I'm currently making a aluminum oil pan for the new engine that should hold around 8 qts of oil and getting ready to port the new 13b rotor housing as well as do all the mods to them so they will work in the 20b.

 

So what rpm does the 1.30 come in compared to the 0.96?

I'm assuming (too lazy to read back!) you have a big turbine wheel.

I have a big Garrett thumper here which is going on when I rebuild, & I have 1.75, 1.51 and 1.32 turbine housings for it. 1.75 would be good for Wangan



My Tech has done that 5000 thing too, occasionally.

Staying on after power-off is another occasional trick they have done since the very early days too.

 

Wow I'm Xtremely late in checking out this thread. Dragon great work. I could see your hard work and determination in starting and finishing your proyect. Must have been a wonderful experience at times

 

lol... the key words in your post were "at times". There was a fair amount of sleep depravation that went along with the work that I think I'm still trying to recover from...

 

He's hitting 16psi at about 5600rpm's(way to late on the 20b)with the 1.30 Q. The same motor and turbo except with a .96 Q was hitting 16psi around 3500rpm's in the FC it came out of. The FC is moving up to a sideported motor and a Thumper 88.
