type 4 turbo guys-, what turbo did you pick and why- Options

[ottox914]

Alot of turbo talk lately. Just curious, for those who have been there/done that, what turbo did you pick, why, and if your project is on the road, how do you like it?

You guys might just wana wait to buy any Turbo related goodies.....

I don't tell everything thats going on at Aircooled Heaven all the time...

Remember I sold the 2316 Hybrid out of my 914 a few weeks back....

I wonder whats being developed to replace it???

I'll tell ya...

First I'm going to MELT 3 stock engines! I have 3 good solid cores that run great and are going to be my victims as soon as the prototype header/ kit is finished. The prototype system is being made so we can make changes on the dyno and then when the best combos are found it can be stretched into the 914 and made to physically fit THE SMART WAY. No Turbos in the engine bay and crap like that!

So I have a 1.7, 1.8 and a 2.0 all that have a date with Doctor death. The engines are all 100% stock and since the only way to find what the stock engines will take boost wise before failure with the end user is to melt them in development. This way I will gain TONS of data to help guys with stock engines know the limitations of boost both intercooled and non intercooled as well as water injected. I plan on killing a couple of these engines two or even three times to see the effects that my DTM has on them as well as intercooling and water injection.

So far I can say that I will be able to provide a full assembly for the serious Turbo spower seeker but I DO NOT plan on selling just a couple of components. I will be doing all this testing with several standards. My target is to complete a kit for the majority of guys here that have a stock engine, no matter the displacement. The kit would allow the stock engine to be removed,(NOT DISASSEMBLED) all my goodies bolted on and then the entire set up to BOLT ON and provide an effective Turbo engine. My testing will allow me to pre set the waste gate and even upload fuel MAPS into the ECU to further increase simplicity for the end user. Thats what testing enables us to do!

So far the kit is being based and tested with the following items being provided in the kit.

-914 DTM
-Replacement rain tray modified for DTM
-Intercooler
- RAT-SDS Based EFI system complete from the fuel pump to the pressure regulator(you just provide fuel lines)
-Complete Turbo arrangement including header, Turbo, Waste gate and all plumbing, clamps etc. All Turbo components will be ceramic coated
- Installation DVD to aid with tuning as well
- Optional Water injection arrangement.

Everything will bolt into the 914 with no cutting of the body and no welding/fabrication required.

I have NO intentions of providing a Turbo arrangement for the TIV engine any less complete than this, and I don't plan to make it work with Carbs, or with the stock cooling system- Thats out of the question because both can get the end user in serious trouble fast!

There are limiting factors that impact the TIV engine when Turboed and I have experienced many of them first hand. The intercooling will solve most of them and the DTM will take care of others. My testing will show the others because I promise you I will push the engines to the MAX to find the acceptable boost and power that each stock engine can take.

After the stock engine testing is complete (probably by February at latest) I will then test my newest Turbo engine design, the 2081. This combo couples one of my 80mm cranks to a 91mm custom piston used inside a stock 1.7 cylinder for the best head seal without having to run Nickies. With Turbo engine size isn't the key- Being able to hold boost is the key to making power reliably and this combination I feel will work great! This 2081 engine will be getting internal changes made to it many times on the dyno before getting installed completely in my 914. The Southeast Dyno day is the 2nd weekend in March and its my goal to have the 914 there making big power for the crowd so I can keep my crown for the 3rd year in a row. Target HP is 240 at the wheels! Target boost is up to 20 PSI intercooled!

Now, please limit the questions about the size Turbo and etc that I will be equipping the kit with, because I have no idea! I have 4 different Turbos to test with it and at least 2 different compressors will be used for each one.

I have been working on this for quite sometime and my fabricator is REALLY working his ass off to help me get the header work and plumbing all designed correctly and the smart way. He has mondo experience with the Rice Rocket crowd in the Turbo arena so between myself, Len and the fabricator we are all putting our best efforts into making the phrase "You can't Turbo a 914" a myth.... The problem with ill fated Turbo 914s before is the fact that they were never done correctly and no one knew the limits- Thats not the case this time, this is a HUGE effort..

The reason I'm doing most of this Turbo first with the 914 is because I feel that while not many teeners are spending money for my complete engines these days due to cost that this Turbo set up will provide another option for the teener and it will be a product of mine and no a full engine. What I'm trying to say is if you can buy a Turbo kit for less than my complete engine and make MORE power I think it will wake things up a bit for everyone.

As for cost, no idea yet, but you do not want to see the budget I have planned for this development. In fact the entire year of 2006 is dedicated to Turbo development here and it's all I'm going to do.

You guys know I do things right and well thought out. All of this takes time but I don't see a reason in the world that we can't have the kits for stock engines ready to sell by summer 2006.

I'm away right now on my laptop on a mini vacation. When I return I'll be gearing up to melt the first engine, a 2.0 914 spec engine that has about 80K miles on it and then the fun will begin!

Be looking for updates on my forum as things progress and I promise they will progress fast.....

Now you know why I installed all the new computer equipment and the second dyno!

Its all about removing the guesswork!!!!!!!! Done-
