Don't kill me I searched lol. Does anyone happen to have this setup from rx7store.net? I am looking to see the spool range to hit boost. I was talking to pineapple racing and they said I would HATE the spool on the A/R.

Input would help.

Car is a 1992 FD3S
Motor will have a large streetport from pineapple

goal is a weekend car around 450bhp.


Thanks

Seth

 

I'll post up my dyno sheet soon for you. But at 450whp u need to look into race gas, e85, or methanol as on the 35r it will take 18+ psi. Also I hit positive boost by 2k rpms and full boost by 38-3900 rpm.

 

I was figuring on some sort of additive such as alky injection etc.

I look forward to seeing your dyno.

I figure the principles I learned building track Evo/STI's will carry over to rotary building at some level....even if only elementary.

 

I made 455rwhp at 15psi with my 1.06 Gt35R with a street ported motor.. I made 515rwhp at 23psi but thats all she had left in it. I saw 10psi by about 3500 and full boost by 4500rpm. I have videos of the dyno passes on my youtube page I think I show the graph too.

Thanks for all your help guys! I am reading so much tech stuff trying to learn the rotary better I feel like my head is going to pop. For being honestly less complex than a piston engine it is still complicated.

 

I have the same kit. Ask for a divided housing since the manifold is divided, it will help it spool a little earlier and he'll send you an undivided if you don't (I made this mistake assuming it would come with the divided housing). There's also a ported shroud option that I didn't know about before that allows the turbo to flow 70lbs of air a min instead of 62lbs. Since I put the ported shroud on the sound of the turbo sucking in air is much more pronounced and you can hear it around 2000rpm where it starts making positive pressure. I hit ~17-18psi around 3800-4000rpm. It's a blast to drive around since the car is so streetable and when you're not getting on it but is a real animal when you open it up.

The new manifold Jason has is great. Just make sure you are getting the new downpipe made for this manifold because the old one I'm using doesn't fit right with this better manifold. If you don't like it loud you might want to have the WG rerouted to the downpipe cause if not once it opens it will be loud. If you don't mind it being loud just when you're flooring it then it's not a big deal. Also make sure you use coolant line meant for high heat cause I was a dumb *** and just used regular hose from NAPPA and after a year one of my hoses cracked and leaked coolant all over the last time I got on the dyno.

Dudemaaanownsanrx7 is a forum member that sells a simple easy preturbo pumpless water injection kit on his website wannaspeed.com. I'm using it and love it. It will allow you to easily and most importantly, safely allow you to drive around all day long in a bad *** 450whp FD.
