Congrats John!!! Glad to hear you are enjoying your car and happy with the results thus far. You will be in good hands with John and Paul @ Protosport. I'm looking forward to your impressions after the tune.

 

Congrats John...

I am a fan of the K24 based turbo. It has been hard trying to convince people that when done properly they are a very responsive turbo.

Todd is the man when it comes to maiking the most of the K24's

Have fun

Tom

 

Thanks, guys.

Tom, I would have to agree - this package is unexpectedly responsive. I was prepared to have a little lag and took steps to try to minimize it. In the end, I just don't feel any lag. I think I had more lag with my K16/24 set-up than I do now!

 

John, it may be a combination of ur air delivery.... liek the TB, ICs, plenum, etc... it still is a bigger turbo then the k16/24... yet when properly put together it seems that it does what it says it should....

Mark,

All I can say is that I am extremely pleased with the way the car drives and responds. When I drove Bill's car, I hit the gas and waited for the turbos to spool and get going. I remember the delay and then the big push. I weighed the tradeoff in my mind and decided to try it for a change. I was expecting similar lag, but slightly reduced lag, due to the air flow modifications you mentioned. What surprizes me most about this package though is the "instant on" feeling of power. I'm thinking the fuel delivery and larger injectors have a lot to do with it, but I'm no expert - so I really don't know for sure.

 

That's pretty interesting the new MAF housing looks to be a C&L along with a with a different flange welded on. The MAF electronics are Hitachi and the same as those used by Ford for ECC-IV (vintage 86-93) and ECC V. Transfer tube is also from C&L . Here is what I am referring to (the extreme end not the feeder tube) or the unit same unit sold by Vortech (http://www.vortechsuperchargers.com/...=27&cat_key=4). The size might not be as large as the one used but larger ones are available. Different size transfer tubes allow you to avoid pegging the MAF.

I was wondering is any screening included in the MAF housing provided ?

 

What would be the benefit / negatives of screening?

 

Its a ford MAF.... maybe actually Hitachi. widely used in mustags I believe.
ist just like mine.
the trick is to know how to make it work... and Todd K. is one of few.

 

That Is A Huge Y Pipe!!!! Mark, Todd Dynoed My Car At .8 Bar Thus Far It Has Made Some Great Numbers (around 550/550 Rwhp)!! Should Easily Make Much Higher Numbers When Push It Up To 24 Pounds Of Boost! I Was Hanging Out With Some Supra Buddies This Weekend And I Am Amazed How Big There Piping Is Compared To Porsche's! Seems Like Todd Is Doing The Same With His Stuff!!!

 

A screen promotes laminar airflow over the MAF sensing element. The MAF is designed to operate in a smooth relatively turblence free air flow This insures that it will produce repeatable readings. If the element is in turbulent flow it will produce erratic readings and confuse the ECU (not sure what the motronic s/w does with erratic maf readings butit can not be good).

Clocking of the MAF housing (rotating the sensing element along the tube's long axis) and also placing it in a straight section as remote from bends as possible helps to avoid this. The straight length where the MAF is installed should be at least 2 diameters. Air filter design and proxcimity to the sensor also has an impact.

The standard OEM proceedure is to use screening upstream of the MAF (as used in the Ford application of the Hitachi electronics). Negitive is a small increase in restriction in the intake tract. A common "modification" is the removal of the screening usually resulting in generation of inconsistient and inaccurate MAF output.

 

Killerbee,

That's interesting - it does look to be the C&L housing, just without the additional mounting flange shown in the link. Todd/Protomotive does not use a screen.

 

Killerbee does bring up a good point about the screening. Might want to ask Todd about that. Seems like you would get more accurate reading with one installed.

John, with your fuel upgrades I was wondering if you retain the factory lines or replace them with larger ones like EVOMS does?

Good to hear you are happy with the way your car turned out, cant wait to see those 10 second slips!

 

Don,

I'm sure Todd would have included a screen, if he felt one was required. Protomotive runs the stock lines with the 700 package - no need for larger rails according to TK.

Don, I don't think 10's are that easy - your putting a lot of pressure on me - especially using the plural "slips". I'll be happy with just one slip. It will be really interesting to see what it does.

 

Here are a few final pictures of this project showing the Greddy boost controller installed.

Very nice projet !!! when it's all done get us a youtube presentation
congrats on good work
