Can I ask you why you are still posting and not working on this kit? Lol

This quoted,
I actually emailed them a week ago to find out and this is the email I just got today:
"The full kit with a t70 runs $3200 and comes complete with everything you need
minus fuel and ignition. Add about $1000 for an A/W intercooler. Please call the
shop and we can discuss your combo and performance goals."
from here,

If it were me, I'd like to see a kit for the stock engine that would be basic bare bones, weekend install, ready to go kit. Then I would like to see another section that would provide upgrades that a "budget minded" mechanic/weekend enthusiest could buy and upgrade as time and money pemits.
I myself find it hard to spend loads of money all at once for 1 huge kit. (family and other priorities) It's easier to budget a certain amount of extra money every so often, to upgrade/build on the 1st basic kit, and buy more HP in steps.
A "how much HP" boost could be documented to known stock baseline engines for each part/kit/addition. But, with this said, not everyone would buy all the same additions in the same order, thats the reason I say extra HP over the basic bare bones kit.

If this kit is done as nice and the RPS kits with some competitive pricing I'm game.
Joe,
You may, or may not be interested in my Vortech supercharged 360 Magunm build that runs approximately 116mph in 11.50s in a '72 Valiant 4-door sedan, at sea level. I wish I had turbocharged it instead, but I have no welding skills, and this was a do-it-yourself project, so I needed something I could bolt together. The engine is bone stock, including head gaskets, except for some very minimal bowl porting (no gasket matching, even, except for the valve train which includes a very mild Hughesperformance cam, stock roller lifters, and some heavy duty pushrods, springs and Crane aluminum roller rockers.)
The intake is a Power Products Air-Gap copy; the carb is a Carb Shop modified blow-thru 750 Holley d.p.
TTI headers and exhaust (2.5") H-pipe.
445 rwhp and commensurate torque.
Like I sed, stock everything else.
Snowperformance Boost Cooler meth injection; MSD BoostMaster ignition (analog.)
Here are some pictures.
Here are some pix....
The engine went from 260 rwhp to 445 rwhp with ten pounds of boost and changing from early 340 ex. manifolds to TTI headers (oh, and the P-Products intake which replaced an M-P dual plane.)
I really does feel like a big block through the mid rpm's. LOL!
Luckily for us we are dealing with decent sized v8 engines, Even a bone stock smog 318 would make 300 horse at 3 psi or so. The plumbing will be the heart of the system and everything else can be swapped. The key is to get these on cars so all of us can play,whether it takes your 185hp motor to 300 or your healthy 425hp motor to 600+ EVERYONE WINS . I think I will offer the kit in 3 different power levels ( fueling and supporting mods aside ) stage 1- stock to 450hp stage 2- 450hp - 600hp stage 3- 600 - 1000+ And the option for kit with no turbo and kit with custom turbo. This should easily cover everyone and you can trade up or down in a fairly painless manner.
I'm very interested! Your build just shows what I'm trying to hit home ( bolt on power ) almost 200 more rear wheel horsepower is awsome! I'm sure you can attest that if you could reach your highest peak tourque at say 3000rpm and keep it all the way through you would do it and a turbo could do that for you AND BEST YET!!! You have all of the supporting mods. You've done a great job with those numbers... In a four door at that

I will take a stage II...sign me up what's next? 2-6 month wait?
Not that I'm anti turbo, but.........
How much power does it take away from the engine to spin that turbo?
IF the turbo has to pressurize the engine, the impeller has to have some force put on it in order to spin it to make pressure. Once the engine is under prssure, there has to be more force required to spin the turbo in order to maintain pressure.
This is back pressure on the engines exhaust side. This has to cost power in some way shape or form.

Nothing to see Here!
Making a 1 off kit to satisfy everyone's cravings will be almost impossible. That is why most guys go for the custom set ups. The guys that want a bolt on done type of system will need to be satisfied with the way it will come and the max performance that is attainable with it. I do know this, no matter which way you choose most will upgrade to go faster and faster like a Crack Addict chasing their first hit off that Magical Glass Pipe! :toothy7:

blowers suck up power because the engine has to physically move the gear to greate boost, turbos make free power using what the engine wastes, exhaust. turbos are nothing but + numbers, theres definatly no loss. either way anything forced induction is going to but way up im power, unless theres something seriously wrong.

One thing you need to remember is nothing is free when it comes to forced induction. Gear Driven Superchargers do however take more power to operate than an Exhaust Driven Turbo. You are using exhaust gasses to spin a turbine which scientifically will use up power to do so, but the loss is minimal compared to a gear driven unit. Try and spin a Gear Driven unit by hand, now do the same with a turbo, you will see the difference right there.
You can actually blow air out of your mouth into the exhaust in on a turbo and it will spin. Try that on a Gear Driven unit!

I usually try on to put my mouth around my exhaust.. but if I do have a nice turbo kit I might just have to try it. :happy7:

You don't need to put your mouth around it, just blow into it!:?
They say a mechanical water pump takes 15-20 HP to operate. A gear driven supercharger has way more resistance than a water pump.

The biggest benefit IMO is the amount of power turbos make vs blowers size for size. It's seems blower guys are always chasing their tails trying to keep that belt from slipping when they get up in the higher boost levels. Turbo guys have to deal with the amount of room that's needed for all the plumbing. To me turbos seem to be more technical with the correct size plumbing, intercoolers, BOV, waste gates, AR, etc... Superchargers are usually just a bolt on kit with little plumbing.
It's hard to say how long, The companys I deal with are closed on the weekends so nothing new yet, Hang tight.
This is why if ANYONE is interested in a kit they need to be completely honest with themselves and not get the wrong power level kit for there build. If you have 280 horse 360 please don't purchase the 1000 HP kit it won't come on until 7000rpm. When this is all worked out ill be able to help choose a size to suit your needs if. Your realistic with your goals.
And yes boost is like crack
It really doesn't work the way you think. Off boost a turbo system is very free flowing they have to be or else they would be even more lag than usual. If you have a properly sized turbo setup you will have some lag, You will never notice a restriction off boost even with a back pressure gauge. And when the boost comes on you'll never worry about that again
Your right about belt slip. Centrifugal blowers are gear/belt driven turbos and somehow are sold as 1 size fits all... Maybe with different boost levels via different pullys. And they do work but you only get max boost at max rpm they increase in boost all the way to redline. The true benifit with a turbo is the massive power curve you will achieve not just as the rpms increase but everywhere

I'd be interested in just the hotside and downpipe. I'm guessing you're gonna set it up for a T4 turbo?

There is alot more to adding a turbo than just headers and the turbo. Heads come into play as well as the ever so important cam choice. There are alot of factors that need to come together than just slapping a turbo onto a engine. Gonna be hard to confirm exact horsepower numbers for a given setup unless you provide a complete top end and cam selection.
