If you stay within the high efficiency area of a turbo, running a 40/14.7 pressure ratio at whatever CFM the RE can flow at 8500 rpm or so, you'll get better power.
Now we will have to see if the injectors can push enough gas... and the ratio has to be (well i like it around 12.5 under boost .. yest i am running at10).... and timing Degrees just soooo much more that i am not going to get to....

One factor that determines how much power you can make is how much air you can jam into the engine :
What are the variables ?
Its pressure
Its Mass (affected by temp & humidity)
So - big turbo = less heat = more power at the same pressure .
am i missing something ?

335hp/255tq 12psi, blowing out the spark badly, or we would probably be seeing 350+. But being California gas, didn't want to chance anymore. I will upgrade the ignition system shortly and maybe do a pull next week.

So 12PSI was blowing the spark out - I'd be curious to see what you got at 10PSI - and if it was 100% rock stable.
I, like most others here, i think we would only be interested in cofigurations that are 100% stable and reliable. Will be fun to see how far you can go and still be that way.

it's safe to say that this turbo kit is capable of so much more than the engine can handle on 91 octane. i'd love to talk shane into some alky injection and maybe a tank of race gas, so we can show off what not only the turbo kit, but the engine is capable of as well.
hands down, the very BEST kit available for the rx8, and one of the best, and most complete turbo kits i've ever installed on any car...and i've installed a lot.
hat's off to mazsport for making this thing!

Curious - this kit supposedly comes with upgraded injectors and the fuel pump but they were still getting the spark blown out? what is involved in solving the blown-out spark problem?
And still no answer - will these kits be available for purchase? or is there a 6 month waiting list or something?

Any chance Scott will offer the same kit sans Interceptor-X once the reflashing becomes more readily available? If I remember right the complete kit was ballparked to be in the 6k-7k range and that was before the ingition upgrades. Being able to trade in the aftermarket computer for a reflash would be a nice leg up on purchasing.
Also Scott I know you initially said no but if the response is strong enough would you reconsider CARB certification?

6-7k was the rough est. for the type-1 kit. i don't think any one of us have even a slight idea about the type2's price.
what kind of safety mechanism is normally used with the water-injection kit against dry-runs? also... what's the water consumption like when you're boosting? i guess i'm looking for a very rough est.

Then again I may just be being overly hopeful.
P.S.: In case people aren't reading it. Here is a link to pricing for Scott's various turbo kits.

That's probably why they call it Type 1, 2, 3 instead of Stage 1, 2, 3. Numbered stages would hint at increasing performance as the stage number increases.

Type 2 looks really sweet.
The prices look inflated because he's putting all the additional add-ons into the kit.
If you took a greddy for 3.2k, added injectors, fuel pump, int-x, etc. The price would be just over 5k.

i'm not sure exactly what is included in the exact kits yet, but if they come exactly as i installed shane's kit, that's a great deal!
when you think about it, a normal turbo kit for a normal car can run $3kish or so, then the ems, then the injectors, intercooler, and pretty complicated piping for the rx8 chassis, downpipe, ceramic coating, fuel pump, regulator, all the hoses and fittings, etc etc etc....
i do ground-up buildups that exceed $10-12k all the time, so i persnally think the kits are great deals. much simpler than piecing everything together yourself.
can you do it yourself and save some money? sure you can...that's true with just about everything. but the time and hastle, as well as lots and lots of tools that not everybody has... let me put it this way; if i owned an rx8, i'd buy one of these kits before fabbing up something myself. the time-to-cost ratio would work out for me.

w/ 93oct pump gas and all issues ironed out, how much whp do you think type-2 will put down?
i guess i'm curious to know whether it'll reach 400rwhp.
btw, where is that screw that you were talking about for bringing the clutch engagement points closer? thanks again

There really aren't any issues. The kits lay down alot of power right out of the box. The issue is CA gas sucks. As such, we can't run as much timing, and I will be upgrading the ignition a little bit to be able to compensate with more boost and fuel. Honestly, we could probably be laying down 320ish at 6-8PSI, but I asked Scott to tune conservatively, because Oxegenated SoCal Summer Gas is really closer to 89 Octane than 91.

by issues, i was just specifically referring to the ignition sparks. kit looks good. i won't be getting it mostly because scott's doing a 20b swap for me, but am still curious to know what i'm missing out on!
congrats tho! dyno chart once everything is worked out would be very nice.
i'll put up mine once scott's done w/ my car

I tried to pull up the dyno graphs posted earlier, but it's not working very well on my pc. When is it that you're seeing full boost?
