REW Sequential Dyno - very uncommon results

If you have another dynojet just take it there for a true best case scenario. Its not a big deal either way, but 330rwhp on 9lbs is hard to swallow on the stockers, I dont know if anyone has made that on the BNRs even.

I know it is, which was kinda the whole point to the tread.

These are the websites to the two local shops. I'm inclined to take her to ICS just because they have the dynojet, but I'll be more than happy to go to The Shop if you would prefer to get some dyno dynamics numbers. I'm curious as to what the "correction factor" is or what the math entails.

13B-RE, RE housings, and 9.0 comp rotors. Renni E-shaft and stat gears, everythings been cryo treated. I rebuilt the engine using new corner and side seals. Side Seal clearance is 1/2 what Mazda min specs are, new Rotary Aviation Super Seals and race Springs. New oil control rings and MazdaComp springs.

Intake - we'll call it a Med street port. I spent about a day or more cleaning up the runners, bowls and portmatching the LIM to the block. The UIM to LIM is also portmatched as it is to the TB and the TB to the modded Greedy elbow. The TB itself got a little polishing and the 2nd'ary butterflies removed. Modded the y-pipe to remove the stock BOV port, seperated the chambers and built my own x-over pipe, much like Garfinkle did. Everything's been ceramic coated. HMIC, I'm not saying the name of the manufacture, but it is a damn heavy intercooler. 3" x 22" I believe.

Exhaust - RE housings ported with the Pineapple Racing EP2a Template and REW sleeves. I plugged the exhaust recirc port. El Cheapo DP with header wrap. Magnaflow 3" in twin 2.5" out presilencer and two Magnaflow 2.5" in/out cans. All sequential hardware intact. Ported the WG and ceramic coated everything.

Motec M820 ecu, 750/1000cc injectors, Cosmo pump, Aeromotive filter and Mini regulator......

Exedy Twin Disc Clutch, Torsen rear with 4.11 gears and 255/40/17 tires.

I think that's about all the pertanent info.

DING DING DA DA DA DING!!!! This is the exact reason I chose the RE over the REW. In reality they would've required the same amout of work to install them in my FC. I chose the RE becuase the UIM lends itself more for torque, the runners have more "balance" between them than the REW's LIM, runners are larger (which as dregg pointed out will move more CFM at the same boost level) and years and years ago when I was doing my research I was informed that the GZ LIM won't fit on an REW running twins and the whole point of this build was to stuff the best auto-x engine I could build into the chassis. End goal being a few dyno charts like Dans. Depending how far off I am, I may be finding a set of S5 rotors over the winter.
