i didn't mean to suggest using a 93/100 mix. straight 100 is the best way, however you should purge 93 from tank as completely as possible.

my comments are based on my seat of the pants reaction to 100 octane in my car. since increasing boost is only going to make more heat my reasoning it that the 100 octame should be more of a benefit. if a stg 2 evosport makes 435 hp on cali 91 octane and the sl55 intake adds 10-15 (440-450hp) then shouldn't 100 octane get to 470?

i'll know by next 4 weeks i should have a full stage 2 + car by then. if you have results of a repeat stg 2 on 93 /100 then do keep me (us) apprized.

btw the evosport headers are on back order i'm still waiting on mine.

i second this

I would like to try it. Any in the San Jose area have one of these installed on their cars?

I was on E when I added the 100, and I filled up. I didn't feel anything seat of the pants, and when I went back to 93, the car felt the same.

Stage 2 already includes the SL55 splitter and pipes. I assume you mean the extra 10-15 are from the SL55 boxes, which stage2 does not include. I don't think they do much. The 10-15 number has always been from 'well, those SHOULD add aboout let say, ten to fifteen hp.' I'm starving for more power, but I won't do the 55 boxes unless someone showes me hard proof that they produce a significant gain.

I'm going to dyno on 93 then 100 regardless. I'm still curious.

Thanks bud! Can't wait to see what that monster car of yours does!

You guys win...

I'll order them tonight.

guess the opportunity for stage 1 vs stage 2 is LONG gone

Yeah, I knew we shouldn't have waited.

What's next for our cars?

Dunno. I want some more power, but I wont use n2o. Renntech said they have nothing for me, Evosport said they might be able to do tb/head work, but only if I transport the car over there.

Cams look good, but I'm not willing to spend $5000+ (part&install) for 15hp

Anybody have a custom front mount intercooler? My kleemann clk55 has a front mount intercooler but its too small. I am looking into a custom one to help with the heat soak issue. I already asked Cory about race gas and he said the max you will see is 10hp because the ECU is tuned for a max of 93 octane (well for me it is). I'm going to try it anyway when I go to the track. It cant hurt.

I'd suggest a Quaife LSD. You need something to help get all that power to the wheels.

You can't use an air/air ic with a C32. I think that the most promising ic upgrade is using a closed loop system with a compressor in the trunk. There is another active thread about this

You are correct there is no economical way to replace water/air with air/air.

Ultimately we are limited by the ability of intercooler core to absord the heat and move it out.

My nex step is to increase line sizing from the core and out of the core, to match Johnson's pump outlet/inlet (0.75'' vs. 1.5'').

To get over 400 RWHP - head/cam work is needed. Adding more boost will only increase air charge temperatures.

I never found anyone willing to work with me on the Johnson pump, and I tried hard.
Using an external electric cooler with a bigger pump would help BIG time. I want to do it, but I'd rather be the second guy.

I was talking about just getting a bigger front mount. Not switching from water/air to air/air. I already know air/air wont work on our cars without major modifications. You dont think a bigger intercooler will help prevent heat soak? Although I do see how if it gets hot it would take longer to cool down.

After normal stage2, it is probably best to port and polish the heads and match to the manifold. There some people that rework the positive displacement blowers. Then do the cams. Need to find someone, with experience, who knows how to do the C32 heads properly.

For optimum power output one should get more air volume flowing through the engine, with less loading on the blower. This will actually give you less boost pressure, but more airflow. It will make the blower more efficient, since the total pressure on the outlet is lower. This should also lower the IAT temps.

I'm about to install Stage II, and you guys have me nervous that I won't be happy enough with it. Power corrupts, and absolute power corrupts absolutely...

It is possible, but there is very little extra room upfront. A new front bumper cover that can accomedate a larger heat exchanger will work, but it would have to be a one-off$$$$.

Check my sig, I will switch the bumper from my other car. I think theres plenty of room with that bumper! Oh yea, I was referring to my clk, sorry.

In that case, than you will have the room to do it.

However, if you are reffering to improving Kleemann system, than it is already very efficient. At only 7 psi there is very little heat produced. Stock Kleemann setup gets close to 90% of efficiency.

best case is getting the fluid that circulates around the core to be ambient temp.

i have an oil cooler (that's not connected) on my swift that looks like it coud be fitted to the front of the c32. this, with the evosport split IC cooling(windsheild resevoir) should be of benefit. an upgraded pump could be of benefit as well but not sure it's worth the bother.

also- for NA cars the advantage to using hi test is much less than forced induction. this due to the increased IAT on compression.

Are you referring to me? Because my CLK55 is not N/A, its kleemann s/c

Vadim, clear out your PM box...

do you have any pics and/or the dimensions of the stock C32 intercooler?

i was but stand corrected. put some 109 octane in that bad boy.
