Sorry, I could not resist the desire make a poop joke........

LMAO!

11/24


Got the quick release and steering wheel installed




Ford Racing Steering Wheels - M-3600-R


Sparco Hub Adapter - 01502067CA


Watson Racing Quick Releae Hub - WR-QUICKRLSE (Same as the Sparco...but WAY cheaper)



The install



Went over to local Fastenal shop and got some longer M5 flat head bolts and nyloc nuts, total cost was about $3.00





Just waiting on a Watson Racing display/dash bracket so I can get they RaceCapture setup installed and configured

 

[j3st3r]

Last night got the Watson Racing bracket installed, and did a couple mockups for AIM MXL2, and testing for RaceCapture setup, in preparation for Barber this coming weekend

RaceCapture is good stuff! I think you are going to like that quite a bit.

Can you send me more info/purchase link to the AN vent filter-fitting shown in this pic? Thinking to do something like this for revised fuel vent system in the works.

Re: Project DRKHRSE 2013 GT Build

That is my vent for the diff cooler/vent I built. The picture shows a -6 an fitting with what is an off the shelf sintered mesh air valve muffler/silencer. I might have a few of these laying around I can send you

McMaster Carr should get it done if your looking for the sintered filter

 

[F.D. Sako]

Let us know how you like the racecapture app!
I just got the new RaceCapture unit and I'm looking to do a similar setup with a smaller tablet mounted somewhere on he center console.

 

[j3st3r]

Decided on a different route for now


AIM MXL2 setup with added sensors for Oil Pressure, Oil Temp, Brake Pressure

 

[302 Hi Pro]

J3st3r:

I like the looks of that sandwich plate for the sensors, any manufacturing ID on the part? (I'm assuming it came with your AIM kit.)

Need to locate an oil temp sensor.
Thanks,
2HP

It did not come with the AIM setup, its a ProSport M22xP1.5

Nice!

Thanks so much,

Some more parts for the new year


-MGW Race Spec GenII Shifter



-Ford Performance 3:31 gears


-Ford Racing Rear Studs....finally


-Jacking Plates


-Fumoto F-107N Oil Drain Valve

 

[VoodooBoss]

Looking good. Have a few extra drill bits handy when drilling the holes for the jacking plates.

 

[j3st3r]

Forgot to add the homemade cool suit cooler setup!

 

[j3st3r]

Got everything but the gears installed this past weekend, gears get installed on Monday.


Have to say shifter install went MUCH better than I thought it would in reading some of the installs.


WHAT a difference the MGW shifter makes!




out with the old


New one installed





Had to trim the Roush side skirts a little to make room and access for jacking plates

Curious why you chose 3.31 Gears if you have 3.73's needing longer gears? I only ask since i have 3.31 and wouldn't mind going to 3.73's

I'm curious also, I know Vorshlag is proponent of this, but I haven't heard the particular reason. I think they have said something about keeping the engine in the middle of the torque band.

Not sure I buy that.

I was thinking the taller gear was maybe just to do away with extra upshifting and downshifting which might be detrimental in certain tracks. Maybe promote trying to carry speed through corners rather than thrashing down and up through the transmission.

I always geared my old racecar for short and long tracks and preferred running a short track with say 4:30 in third/fourth gear rather than 3.70s in second/third gear (a generalized statement here) trying to run in a stronger gear in the transmission that is closer to 1:1.

For my GT350, it has a larger rpm spread and there are no tracks I run that I will hit 165mph. I was thinking of dropping 3.91 v 3.73 gears. First gear in the GT350 is quite tall in comparison to a GTPP car.

Since I've been summoned ;D

Factor #1
What we found was that the S197 GT engine had a significant torque bump in the middle, but horsepower tapered off at the top. This is relative to the BOSS302 engine, which actually had LESS power than our GT in the midrange, but at the very top it kept going while the GT topped out.

Factor #2
Instructing students we found that when they kept the revs in the top of the power band that shifting was harder, balance was harder for them, and that the car was just more frantic.

Factor #3
Heat. And lots of it. On any car with the short 3.73 gears and a Boss intake we found drivers kept the revs at the top of the rev range so they had adequate power. Extra revs to get the power create a lot of extra heat. More than the BOSS cooler could fix. More than an auxiliary cooler can fix in some cases.

Factor #4
The good tires were short! Like really short. The popular 315/30-18 tire, which was THE tire at the time, is very short for the S197. FWIW, for competition purposes it is still THE tire you want to use if you want to win. But, the couple tires in that size are a hassle, so I only recommend it these days for championship efforts.

What does it mean?
In an effort to make the car easier to drive, produce less heat, work with the shorter tire AND have more usable power, I recommended the 3.31 for cars with the GT engine and 3.55 for cars with the BOSS engine (intake and cams). For those that made the change, they saw the benefits including lower lap times.

Today, the S550 GT makes all the horsepower of the BOSS and all the torque of the S197 GT. And, more 305/30-19 tires have come out which is GREAT for track days and casual competition. The heat management has gotten a little better. And it's harder to overdrive the suspension, though the transmission is still not what it could be.

So my recommendation today? It's a little more complicated. The S550 should most likely use the 3.55 gear. It seems to work best. For the S197 I'd still stick with my earlier recommendations. The 3.31 for the GT and the 3.55 for the BOSS. If you are going to run a 19" tire, it's a factor I'd consider, but unless there were some other changes, like a lot of power added, or huge weight reduction, I'd stick to my earlier recommendations.

 

[venom52]

Thank you @modernbeat that answers my question. I'll stick with the 3.31's even though i have the Boss intake i know it's not a Boss engine.

thanks for the response several of these are definitely the reasons....the other thing for me is based on the tracks I frequent(Barber, VIR, AMP, NCM, Road Atlanta) the 3:73 just are not the right gear, at least to me There are several spots on some of these tracks where I either need to hold 5th gear rpm for an extended period of time, or shift into 6th....which is no bueno. There are also several places where again I can hold it on a rev limiter, or shift up, and then have to down shift almost right away. I dont rev my motor out to 7500-8k either, car is not making power in that range anyway, again in my car(GT, non Boss intake) so not really needing to risk components, heat, and wear and tear.
