Yea, Cali 91 FTL.

Guess ill stay at 16psi until i get my AI setup....

Im really sketchy about daily driving a car thats been setup/tuned for AI, if anything fails, im basically fucked.

whats the specs on your AI setup?

I'm installing the Devil's own progressive kit. Not sure on the specifics, but we (Karack and I) are going to start off with the 7psi nozzle and work from there. In the end he's going to tune on the side of caution, staying within the 11 AFR realm just to be safe. Luckily if for some reason I go dry on the Meth/H20, I can always hit up Infineon raceway and get a gallon of 116 for $9.00. Not the greatest backup but it will for a day or two ... good luck man...

Oh! A good idea with any meth kit is to get the level light! It'll save you from the worries...

I was thinking of going with the Coolingmist Trunkmount kit with the Aquamist DDS3 display

~15psi on 91 octane.

~16psi on 93 octane.

That just means you havent been in this game long enough, and havent pushed the envelope far enough

Once you get burned, you'll be more cautious.

I guess.... see the thing is, right now apparently I boost spike to almost 18psi, and it makes some good power, but not enough. If I tune for 15psi im afraid it will be a disappointment, although its said that boost spike to 18psi is different than a constant 15psi.

Ive had WELL over 100 pulls easy with spiking to 18psi(according to the AVCR, 1.21bar) and everything is running STRONG.

I defiantly wont go over 16psi... but not sure wether I should go for the 15psi or 16psi. My AVCR has 2 boost settings (A, B) but I only payed Steve Kan for a aftermarket turbo tune up to 16psi ($550) and im not sure if hes willing to do a "A" setting of 15 and a "B" setting of 16psi.

Im really stuck on having it at 15psi and being able to go to 16psi safely, but then if I go with 16psi and something goes back I will shoot myself.

You're really agonizing over 1 psi

Keep it as 15 psi (esp given the 91 octane), and get that spike taken out of there before it happens on a cold night and frags your motor.

Yea... 1psi does make a differnece to rwhp.... and once its tuned, im not going to touch it, so im trying to get the best results.

Also, I believe my wastage is setup wrong. There is only one line going to the wastegate and thats from the boost solenoid going to the side of the wastegate. Isnt there suppose to be a engine vaccum line going to the side of the wastagate and the boost solenoid line going to the top of the wastegate? This might be the reason why im boost spiking or its causing the wastegate to operate incorrectly?

I have the HKS Standard wastegate (http://www.rx7store.net/product_p/hk...0wastegate.htm)

Can you verify this Rich?

Actually looking around in the original thread, this helps me out more... https://www.rx7club.com/attachment.p...0&d=1169749042

Looks like I should change the setup to engine vac to side of wastegate and boost solenoid to top.


Sorry for all the questions Rich but ive got a couple more lol...

Since youve been around single turbo FDs more than I have with the mods I have and Kan tuning... what RWHP should I expect at 15psi?

Rebuilt 3mm Large Streetport by Pettit
Garret T04R 1.00 A/R Divided
Shorty manifold T4 divided
all fuel mods (1600cc injectors, supra FP, AFPR, etc..)
Crane HI-6 Ignition
PFS Race SMIC

ill be pissed off if its less than 400rwhp .... ive gotta a larger turbo than a GT35 and they hit 400rwhp easy at 1 bar




ALSO (:-)) can anyone identify my manifold? (sorry for the cell phone pics)

~420whp

The R is still just waking up at those boost levels.

GoodfellaFD3S

iTrader: (213)

Really, the T04R doesnt wake up until 20ish psi. As you mentioned earlier, getting some water/meth inj to allow you to safely pump the boost up is a good idea. That supra pump by itself is going to be problematic as you go much above 400 rwhp though. At a minimum hot wire it, really you should add a second one if you have high hp plans.

You'll make 400-425 rwhp at 15 psi, depending on the dyno and your motor/ignition.

- With a future meth kit I will run around 20psi.

- Instead of runnin 2 supra pumps, cant I get a apexi BNR33 pump and call it a day untill 500rwhp+ ?

- Anyone care to identify my manifold?

GoodfellaFD3S

iTrader: (213)

The apexi pump should be fine, esp if you give it a better ground and clean up the power wire a bit as per chuck westbrook.

There is a bad assumption here.

It is not boost level that determines octane, it is the power level produced that determines it.

A stock port engine with the same mechanical setup, at the same boost, and same tune would not have blown due to producing less power and less heat.

I'd run a Nippon-Denso (also, RX7.com sells modded denso's) or a Bosch 044 and call it a day. But thats just me.
