So Thats Whats Been Going on........

[eclipsed4seed99]

Although my car has been somewhat lightened up I figured to really go after some weight for this season. Last years race weight WITHOUT driver was 2439, This last winter I have managed to remove another 424 lbs from her. Most of it was getting the obvious the other well it took some work but in the end this is all gonna pan out. From all this I have partnered up with a fabricator who wants to build 1g lower A arms. These things are sick as hell and have been tested for strength with the right equipment to find the failure level, they way out performed stock. They weigh 4.5 lbs each comparing one stocker is about 9.75. PM me for contact on these. I also had ETS back in to redo the turbo set up and piping. Lets say the Titanium is so sweet. I also went out back and swapped in a 3000 gt rear 3rd member and 300m axles and now to finish the DSS 3.5 alumn shaft I finished it out with a 3in chromoly with full sized U joint. The last place I was able to make more power is I worked out a deal to get the other FP HTA 105 turbo upgrade. I'm not sharing specs but it still is a 42r, Sheps 1g has the other one. Metro Trans has also been very busy building a new freshy for this season, Although it wasn't needed the auto that I ran all last season easily had a full season left in it. so here's some pics enjoy, I'll be out to the track testing in 2 weeks.

THE BLOCK TRANS AND HEAD ARE EMPTY MOCK UP PARTS

 

[GRAVEDIGGER]

That thing is going to be wicked. I can't wait to hear what you are able to do with it this year.

 

[FLASH1970]

Looks like it'll scoot... nice work!!

 

[Boomdeeze]

That is some skill right there, great job with the build man.

 

[20psimitsu]

Damn Jeff!! Your car is in for some new numbers. Can't wait to see what you and wholer's cars are going to do.

 

[E116]

Your car is my idol . what are your goals for in the 1/4 mile this year?

 

[Anthony416]

That thing is a beast!

 

[kp116]

Looking good! Looking forward to see this thing kick some more ass this year! You guys going to the shootout again this year?

 

[danl]

Shit just got real son. I was hoping you found a way to lighten up the rear trailing arms.

 

[rowdygst]

dang....jeff by any chance did you moved to san antoino for a bit with a guy named phabian?

 

[dsm-onster]

Not willing to share specs. . .But it still isn't what every one knows is a 42r . . . Oh well, no use taking the record for one either.

 

[VETDRMS]

Looks great!

 

[Bud92gsx]

Thats a awsome I cant wait to see it when It's all welded up and ready do go..Great job..

 

[eclipsed4seed99]

I guarantee it's smaller than Jesse's turbo still. The inducer is almost the same size as 4202 but the exducer is slightly larger hence "HTA 105" but flows 120 plus lbs per minute.

Just for the record as well I will be dynoing this car in awd 5sp trim for true accurate numbers on our dyno jet. Q16 for fuel. Then I will switch the car back to auto.

When your 700lbs lighter you can run a smaller turbo . My turbo is just an off the shelf s374. Your car looks good.

Got some more pix after we got it home tonight back to the shop-

Splitting hairs. No one in the 75.5mm class runs a "42", they run 75.5mm turbos.

I.e.-

Holset HT3B
4276 Precision
75mm BW
75.5mm GTX-R
75.5mm 4202 (there are 2 4202s listed in Garrett's catalog)
Comp 74mm or 76mm "triple bearing"
HTA42R

It's like saying Devin's 3586 car doesnt count because its not a 35R

This is you?? haha awesome ive been following this build on ETS Facebook and never knew it was on the tuners. looking forward to see it run!

 

[greenydsm]

Shouldnt those control arms have some sort of cross beam? It seems weak by being in a V shape

MAD (the builder of the arms) shear tested them and they are stronger than stock actually...at half the weight.

Looking at those intake before the TB and the turbo down pipe, i am little concerned about the amount of turbulence it will create from both end. The square like bends and the welds that are "poking out" inside the pipes will prevent the air form a continue uniform flow. Once those air reached those "bends' & welds" they will began to be congested and will disturbed the velocity. For a higher production of power, every minute detail must be taking into a consideration. Paying more attention to these on a higher productions power car will yield even more power,and responsiveness of the car. And ultimately, lower 1/4 miles time.


This is very interesting and often times over looked. I found this article for Honda, and they have actually introduce this concept to their production cars(particularly in the exhaust area). They pay attention to these little details and put that theory into use with great results. You got a great car going, and you have pay attention to little details like weight, and custom control arms. I bet, if these issue are addressed in these areas, you will see increase in horse power and responsiveness form the turbo. Every horsepower count when you are racing the guy in the next lane to give you that edge.....

Some long talks with Mikey lately, He' feelin very good about his car as well. Seems like if everyones cars survives the summer the Shootout could be very interesting.

Thank you for bringing this to our attention.

Boundary layer disruption is very unlikely actually because of the volume of piping and the actual low intrusion of weld into the pipe. There is more turbulence because it has to make a 90* turn than there is because of the weld. Not our first time to the rodeo and while a high strung NA car needs all the help it can get, a brute force turbo car needs just one more psi.

The main areas that are critical are total air mass (lbs/min) and VE in the engine (cams/head/header) vs inlet temp and post intercooler temp. This car made 1050 on the last turbo (standard 74mm 4202) and ran 167mph in the quarter, air flow is pretty efficiently managed. We have taken everything that was good about the last setup and made it better, what needed work got it. The 3.5" UICP should flow well I think

An example of how we manage airflow into the engine-

Okay to point out how much change there has been, this is the old kit starting with pre install pix-

It was basically an overgrown street turbo kit and intercooler setup that made 1050 that way. It has improved by leaps and bounds.

Yeah, you guys have done alot of work to that car and looked amazing.

But, you are right about NA vs Turbos. But, having the turbo build up boost for that 1psi and fill that boost within that 3.5" space will take time. I'm sure if the turbo is below its efficiency it will be no problem, but if the turbo is at efficiency and having it come up with 1 more psi will take more time. The more time it takes. the less responsive the whole systems gets and the bigger the turbo the more apparent the side effects.

Going with the larger diameter intake tube is a good thinking and that will reduce the air flow "bend before tb" and thus regain velocity. But, the flip side is, the turbo is going to still have to fill all that space with air. If you already see a drop in psi in the large intercoolers, there will be more drop in psi in the intakes after the intercooler due to lager space.

The intake is large and its great but its not efficients anymore. while it fixes one problem it become a problem itself. I do have an idea tho,... Instead of going big to reduce the "bend before tb", try making the intake more of a circular shape when it enters the tb(now, it looks likes a 90 degree when it enters tb). in doing so, you could get away with having to accommodate for bigger intake piece. using a smaller diameter, like 3.0 diameter with circular intake to eliminate the bend.

Man, you guys got a fast car and alot of knowledge and i admire your work. This is just my 2 cents i wanted to share. Now, how bout that shep record? you guys are definitely heading to the right directions.

FYI, your exhaust manifold looked amazing.
