So just ordered my Stillen SC

Instead of adding another w2a why not clock the blower down, run a fmic, remove heat exchanger from manifold and that should give a plenty long enough straight to put your mafs infront of the tb.

Talk to me ... I am planning a 2 stage AIT cooling scenario ...

The heat exchangers (2) are/and would be mounted in front of the radiator with a fan behind the radiator pulling air through.

The Stillen manifold/W2A IC would still be in place but now being relegated to a secondary I/C function, now with the preliminary cooling directly post SC'r.

The SC'r is an upgraded Vortech V2 Si - (very similar specs as the V1 Ti but with a curved gear drive) - about 40% more capacity than the Stillen V3 with the upgraded impeller.

I also have a built motor courtesy of Import Parts Pro utilizing CP pistons 9.5:1 CR hanging there on it's chain just waiting to 'find it's way back home' to the chassis.
Hence the need for more boost.

Thoughts before the plunge ???

Thanks,

hmm not saying it wouldn't work just not sure how effective it would be. my opinion (based only on assumptions) with the w2a is the boost passes through it to quickly to cool it down to much and if it all gets heat soaked you now have 2 points that will be heat soaked, if i get what your saying.one right after the blower and one in the manifold. the best use for a w2a would be to have a large coolant capacity with the ability to add ice on track days. to simplify things i would personally ditch the w2a, assuming it can be removed from the manifold. wich would free up flow also and clock the blower down and run a fmic. now there is no need for everything involved with the w2a like pump overflow. and now that u would have a fmic have one side be one inlet and the other side be a 2 outlet then run those to the stillen manifold. that should also give u a long enough straight for the maf sensors and reed proper ait

also unless your running 2 completely seperate w2a systems with seperate overflow and coolant and pump, whatever temp the manifold w2a ic is the same temp the air right out the s/c will be, so i doubt there would be to much of a gain. intake manifolds get fairly hot, if u push hot air into them and run them through a small heat exchanger inside the manifold that is already hot i dont see how well they cool the air down once everything is up to temp including the coolant for the w2a system, ya the heat exchanger does cool the coolant but how soon does it heat back up? halfway through the manifold? not sure a temp gauge on your w2a system may help

I like your thinking, but how feasible is removing the Stillen plumbing from the intake manifold? Is it possible to use the intercoolers like the domestics use? Then you may be able to get away with using the stock intake manifold. I can't imagine how the piping would run, but I believe that is worth a thought.

Both would come up the passenger side either 2 out the fmic or one then y it off after its through rad support. Even if u cant remove the core from the manifold it wouldnt hurt to leave it in there

I plan on using both systems ... with separate heat exchangers and pumps.

The 1st IC to cool it down somewhat - relocating the MAF's to either side of the 'Y' just before the TB's - The 2nd IC (the original Stillen) would further cool the charge after the TB's and before entering the intake runners.
I plan to tap in to the Stillen manifold to install the IAT gauge thermocouple here as well.
There is room for Aquamist after the 1st IC too.

Just need to keep an eye on the temps on race day.
May not be 100% perfect, but it's got to be better than stock Stillen.

Exactly what does fmic stand for ??? thought I'd be able to figure it out by now - but I'm Irish......there is still time to adjust.

Thanks for jumping in to the think tank !

front mount intercooler, also with 2 completely seperate w2a setups that will be alot of clutter under the hood. even the cost of everything and the headache of making it all fit, for in my opion, not worth the effort. the intake manifold gets hot and will heat soak, instead of 2 w2a setups just get a large reservoir and on race day throw ice in there if u want to stay with a w2a. i feel the fmic is the best option, simple effective, allows maf placement after blower and will read actual air temp going in. no need to buy a complete water cooling system with another pump, installing extra ait sensors, and avoid making your engine bay a clustf**k

Z&I

Thanks for the clarification on the fmic ... :-) I knew what the ic was in reference to - just couldn't figure out what the the fm was !

Under the hood would look almost like the stock Stillen with the exception of the Barrel IC and that would be barely noticeable since it will be cut in to the charge pipe just aft of the SC'r.
The hoses would also be hidden with the water in/outs facing downward.
There would be the extra heat exchanger in front of the radiator on the passenger side and next to the stock Stillen heat exchanger on the drivers side.
The circulating pumps would also be hidden as well.
The AIT sensors would be where they should be...after the IC and close to the TB's.

However, Just had another brain fart and I'm already thinking of another way to do things >>> will discuss this with the shop hopefully tomorrow.

One of these days the car will be on the road again ... I know it will ... I know it will ... I know it will ...

Actually thought about doing exactly this with the GTM Air to Air fmic.

It has 2 air outs (split 45 degrees) and running the charge tubes back to the TB's on either side.
They mount the cooling fan behind the radiator pulling air in and through both the fmic and radiator.

Sounded real good but a few things put the Ka'Bonk on the idea.
1st was the location of the SC'r and Stillen bracket.
The SC'r is mounted up high on the drivers side and is therefore somewhat in the way.

This would probably mean getting real creative running the charge pipes.
There might also be another issue involving clearance since it is designed for use with the Rotrex on the passenger side down low, and GTM has designed their own motor mounts to accommodate their Stg 2 SC'r kit.
There might be a work around on that tho'.
Keep in mind that their kit is also designed for the Rotrex and 11:1 stock motors and lower boost than mine.

However, the biggest wet blanket at the party comes from GTM - not getting back to me with the price and not being able to deliver it in a timely fashion or even at all.

Their fmic is custom made for only them...and haven't been able to locate anything similar so far.

Too many 'if's' to waste too much more time sittin' and twiddlin' - but I did stop by the shop to look at my car and talk things over with the suggestions being made. (thanks for the input!)

On Monday the motor is scheduled to be put back in the car : take some measurements : and to look at how much room there is to make it all fit.

Still keeping this option open for now ... and the Ice Chest is also being planned.

>>> Keep... ...Positive<<<

u wont need to go up and over or around the blower, keep the stillen manifold on and use a fmic with an inlet on the drivers side and 2 outlets on the pass side, or one on the pass side and one on the top, put a 90 on it and route both through the rad support, on the pass side. it should be very simple. the blower is not stuck with the output facing the pass side, it can be turned downward so turning it down will make plumbing easier

airikrankin

iv actually been watching for a good deal on a stillen kit to try this out, cant swallow paying full price to redesign a kit........hmmm u could sell yours and go turbo? hehe


edit: perhaps start a new thread on this, we totally hijacked this thread sorry op

Z&I

This is EXACTLY (well almost) my original game plan ... 'clocking' the SC'r down and going either Air to Air or W2A IC ...
I do think I will still be keeping the Stillen mainifold and charge pipe, routing the Air out straight up from the fmic.
I would also still be able to keep the Stillen W2C system to further cool the charge as it goes in to the runners.

I didn't get much of a response when I threw that idea out to them - probably because they had already just run the oil lines to the SC'r.

No matter - the SC'r has to come off the bracket now anyway - I'm come up with an idea as to how to reinforce it (the bracket) to keep it from flexing.

Someday 'Monday' will come and the car will be back at the track.

LOL - I am (for some unexplainable reason) a Supercharger guy thru and thru!
And being a determined yet somewhat stubborn Irish/German, I will see the project to it's finish.

I don't think we have Totally hijacked the thread - everything we've been talking about is still relevant.

A lot of guys who buy the Stillens want more power (including MIKEY1600) ...only to run in to problems - or worse - blown motors.

A new thread might be a good idea tho' - I'm sure that there are enough interested guys with other ideas as well.

All good, keep going

I'm in the same boat looking for more power, decided to hold off on my plans for now, atm looking at clutch replacements and double check on my tune.
