The current 911tt is somewhere north of 420 hp and nothing to casually dismiss, they can produce 800+ rwhp easily. Don't try that with your crackerbox FD turbos and flimsy chassis/transmission, the car would snap in half.

Beth and Erik Strelniek's FD is just insane. First FD I ever rode in, and one of the fastest cars I've ever been in to this day. That car got me hooked on RX7s

Gt35r would work with a 20b very nicely and still flows enough air to create positive manifold pressure. Remember they move enough air flow for 450+ rear wheel rotary hp. Just because it's bolted up to a larger displacement engine doesn't mean it wont be efficient. It's true this combination wouldn't be efficient in the upper range but the low to mid rpm range would be something fierce. You would get super fast lag free spool and a ton of bottom end torque. All this means is you get one hellacious low to mid range power band. Erik Strelniek's FD is a perfect example of something that's purposely built for low end (hince the 9.7 compression rotors and smallish .94 exhaust housing A/R). This Banzai 20b Fd on the other is engineered for top end.

Agreed with the above. And what's this about flimsey chassis?

james81

Flimsy Chassis? Lol fool.

no_more_rice

FD chassis rigidity is nowhere near a current 911. Fact. The only fool is one who questions absolute facts.

You're prob. right but at the same time, it's not going to "snap in half."

no_more_rice

Ok that was hyperbole, but you get the point. Above 500-600 hp and **** starts to break on these cars right and left (trans, axles, pp frame, etc). It was never designed to handle those power levels!

But the 996/7 turbo is designed to handle it.

out of curiosity what would the cost of a intercooler/radiator setup like this be from you guys?

Gah, if the Internet is true (heh), the RX-8 has TWICE the torsional rigidity of the FD (30,000 N-m/deg. vs 15,000 N-m, deg.). That's insane.

But there are remedies, no? Roll cage, strut bars, engine mounts, transmission mounts, differential mounts, etc.? I doubt it's enough to achieve the RX-8's rigidity though.

I'd imagine the 997-series Turbo cars are somewhere in the vicinity of the RX-8 judging by the 997 Carrera nearing 33,000. Intuition leads me to believe the GT3-RS is probably the highest of the production (non race-spec -- ala GT3-RSR) cars.

Then again, not one of these numbers contains a source or reference...

P.S. The car is gorgeous. I really had my doubts about the red after seeing the engine bay, but when the entire car is in the frame it looks fantastic.

How much did this cost?

It is not a setup that we sell, it is custom specifically for this car.


What is your malfunction? There has not been a thread yet that I have seen you participate in that you have not argued with someone. Always about something you know virtually nothing about and want to portrait yourself as an expert. Shall we revisit the OMP thread?

My car makes over 500whp and NOTHING (I repeat nothing) has broken. Never mind right and left....not to mention that not one of the parts you just listed is even part of the "flimsy chassis", they are all drivetrain components

Go crap in someone elses thread.

Id like to say that I have ordered a omp block off plate, differential brace from Banzai and they are nothing but top of the line when it comes to quality, price, and customer service. I plan on ordering their motor mounts, oil pan brace, and the rest of their block off plates in the near future. Top of the line rotary shop! Thanks Banzai-Racing.

But you should have said drivetrain instead of chassis. All those parts that need to be upgraded are drivetrain related. The chassis is more than strong enough to hold 600+rwhp. That's why you got the responses you did. I think for a 20yr old design (yes 20yrs because it was designed back in 1990), the Fd chasses is still one of the stronger chassis out there.


Edit: Oops just saw Banzai's post!

^ Agreed with the 20 year old design.... Given the factor of technology & manufacturing improvements, there better be more capable cars than the FD.... It's simple progress.

However, the FD is still highly competitive in performance, & unmatched in looks by today's standards.

Comparing apples to oranges really....

no_more_rice

Both are relatively weak in terms of managing 500+ hp. Not sure what climbed up banzai's ***, but I know exactly what I'm talking about: trans, axle, and powerplant frame failures with these cars are extremely well documented at high hp levels. Drive it like a ***** and you might get lucky for awhile.

I agree, but compared to something like a 997 turbo, forget it.

Then dont compare them unless you'd like to start comparing prices as well.

So true

But reading the conv. is so fun.LoL

james81

once again; lol fool. Chassis = frame rails, subframes, suspension mounts, body, etc. Not transmission and axles. Go fap or say something useful to contribute to the thread in a positive way, and if you love the 997s so much go moan on their forum.

no_more_rice

I'm well aware of the definition of chassis and drivetrain components and don't need some pile-on dipshit with a sixth grade education spelling anything out for me. Get the heck outta here, son. My point was not to bash the FD or this conversion but to point out the limitations of this car at higher hp levels. The chassis has relatvely low rigidity compared to other 500 hp cars: fact. The drivetrain components are not designed to handle more than about 400 hp. Fact.

Got the car back on the dyno to clean up some of the upper RPM richness and dial in the gain on the boost controller a bit more. It made 529rwhp at 12psi boost, the dyno picks it up as a max of 13.7 psi with a bleed down to 11.7psi. The Defi gauge reads a solid 12psi, probably just the difference in source locations. We still have some clean up to do above 7500 to take care of the little dip and make the power more linear. Should see 540-550 @ 12psi next tuning session.

Decided to upgrade a few things before then. We have been doing all this tuning on stock 9 plugs and thought it was time to see how the NGK 10.5 race plugs R6725-105 effected things. These are a little expensive but I prefer them as they are the same length as the stock plugs and do not require a shaved socket to install. http://banzai-racing.com/store/93+_r...ark_plugs.html

Also decided to upgrade the Mazdaspeed LSD to the Carbonetics Carbon 1.5 LSD. While I have that out I thought it would be a good idea to install the Driveshaft shop 3" aluminum driveshaft and Chromoly Axles in brand new halfshafts. I believe in upgrading parts before they give out.

Next I will be dialing it in to 15psi, then water/meth and 20psi
