Contour Enthusiasts Group Archives Forums General General Went and saw the Turbo SVT (Lotsa PIcs, dialup beware)

1/4 mile vid.

I understand that. My post was almost all in the past tense. We were past that until he posted attacking me.

Also this is not about a flamewar and that's specifically why I told him not to make it as such.

I'm gonna have to say that everyone has threw in their two cents about this car. Which by any means is a fine piece of craftsmanship! I must disagree with all those people who have said that the turbo is too big and it's impracitcal and blah blah blah. Needless to say, there is no such thing as having a turbo that is too large, if you seem to think so, then may you putt putt down the street forever. I agree, some of the car is impractical, but very nicely setup as well. If the intercooler piping weren't so big as well as the intercooler, the bumper would fit. Half that intercooler would be plenty with smaller piping and you'd already have plenty ground clearance. (As if that is something you should be worried about anyway, for all you with BAT suspension and so on) I must say that the welding job right behind the MAF is quite possible the worst i've ever seen....so in turn i figure it could be place higher up on intake pipe (making that 45 degree bend not necessary) as well as the filter so they are both pointint downwards, quite possibly then it wouldn't stick out to 600 feet in front of the car. The guys that put this together seemed to be clever enough to put something like this work....how can they not think of putting that filter higher. I think with that smaller intercooler and the filter moved upwards on the intake pipe....the stock bumper can easily fit with a bunch of cutting. Probably bolt on like crap, but hey, it's alomst as if it's going to fall off anyways when it's new, so who gives a crap. I am truly amazed at how nice all that stuff can fit in that engine bay.

Also, to those who think the turbo is too big, once (or if) these boys put a low comression head gasket and some forged pistons in, the car has potential of over 400HP with more PSI. Like 20PSI even. (drivetrain work needed respectively) Oh, but i forgot....your little turbo can't seem to make pressure like that, and if it could, it's unusable boost anyway.

I must add that the use of the water to air intercooler for the turbo setup (proposed by Chris) is plain ludicrous. Whoever said that an air to air intercooler is inefficient might have a tumor or something. Well i suppose the water to air is highly efficient using water circulating around a steaming engine, coming off a turbocharger is going to be pretty nice and cold, maybe even cool, how bout luke warm, HA. Good luck guys! Keep shooting for those stars!

For that remark about putting ice in the reservior to make it cool the air even more so than a air to air intercooler can is a great idea as well. I wanna wake up every morning and fill my intercooler with ice, I can also take a cooler with me to work and fill it up on the way home as well! Joy, being practical is great.

Do you know what a Turbo is and what it does? Based on your comments I can only assume you have little knowledge of Turbos and the subsequent systems that make them work. I don't even know where to start nor do I have the proper knowledge/understanding to educate you as to why you're incorrect in some of your assumptions. However, others will be along shortly to explain it to you I'm sure. Good Luck.

All I can say is this is gonna be ugly...

BIGGER is not allways better....

first, zeteceric, please read the entire thread before "going off" on people, Demon didn't say anything out of order (not particularly tactful, but not out of order either)

and now on to Ferktec,

First you say how great the craftmanship is, then you rip it apart, make up your mind.

Who said it was impractical? No one said it was impractical, just that it was the wrong size turbo for the application. There is such a thing as having a turbo that is too large for an application, and this is a prime example of it. He is not making any power/boost prior to 4400 rpm, this is a VERY high boost threshold, and very indicitive of a improperly sized turbo. and fwiw, you are an idiot if you honestly think there is no such thing as a turbo that is too large for an application.

Well, see, they didn't, so it makes the turbo too large for this application. Also, a thicker head gasket to reduce CR is a really dumb idea, no matter how you slice it, certainly a band-aid if I ever saw one. Forged pistons are hardly the issue here either, the rods are most definately the weak point.

Sure, the only way that turbo is properly sized for a duratech is if it is running at LEAST 16 psi, with more like 20-25 being even better. The problem with that is that a stock duratech shortblock cannot handle anywhere near that sort of power. And running that turbo at such low flow will create surging issues, and a high boost threshold, resulting in a very poor dyno curve and higher wear on the turbo bearings (due to surging, though the excess wear is hardly the issue here)

Well, I do know that the kit Mr. Hightower and HMS and StreetFlight are working on use a turbo properly sized for a stock Duratech shortblock, giving a very flexible power curve (and torque of course) with peak power at a level that is within what the stock engine can safely handle (with proper tuning of course) once a customer upgrades the engine to handle higher boost pressures and power output, I'm sure the upgrade path for the streetflight kit is very simple (ie THEN you add the larger turbo) Fwiw, you could do a setup almost identical to the one showcased in this thread, but use a T3 based turbo instead, and make very similar peak power numbers, while having a far more impressive power curve, making the car overall better to drive, and faster. Its all about area under the curve my friend, especially on a street driven car.

What we have here is a simple case of people throwing parts at a car, and not doing the basic engineering work required beforehand.

and continuing
Umm, yeah, and your reasoning is?????

I don't recall anyone saying that an air/air IC was especially inefficient; only that heat transfer from water to air is something like 14 times more efficient than air to air, so therefore a proper water to air IC can be FAR smaller than a proper air to air IC while having the same efficiency.

Actually, yes it is quite efficient, as the water circulates quite quickly, and is cooled by its own small radiator mounted in the front of the vehicle. You obviously have no concept of how a water to air IC works, yet you continue to try to ridicule it, how pathetic. Fwiw, water to air intercoolers have been used in a multitude of OEM and aftermarket forced induction applications where package space limits the use of the much simpler air to air intercooler. There is a time and a place to use both types, and this particular application lends itself to the water to air IC much better than the air to air.

Actually, putting ice, or even dry ice into the reservior of a water to air IC can increase intercooler efficiency ABOVE 100% and is absolutely fantastic for short periods of time, which is great because that comment about doing so was specifically referring to doing it for drag racing. And oddly enough, this is extremely common in forced induction drag racing cars.

and to finish:
Well said, my friend.

To answer the water tank question, it will be a 2-3 gallon tank mounted behind the bumper cover, to the side.
