BMR Tech's S550 Mustang Build: Street/Strip

[BMR Tech]

So I was able to get the car to the track a few days ago.

I cannot stress how happy I am for the first outing - especially knowing how much more is in the car.

Justin@VMP and Ken@Lund have been such great help - I am very fortunate to have these guys involved. Ken has the tune down really nicely at this point, but he still says he has more to do.

Anyhow, here is the Video Link Justin @ VMP Shot:

I am attending/racing the car at NMRA Bowling Green - So I am now changing a bunch of stuff around, and will be posting pics in a few hours of some cool new parts and upgrades.

So, up first we have an 8-Rib conversion kit from VMP Tuning.

I acquired various sized pulleys. I really want to keep the Nitrous shot (not being used yet) to a 50-75...for cooling and launch purposes, not specifically for max power purposes.

The bottom pic, above, is the new Low Profile 20% stiffer low profile tensioner. This helps with clearance, and belt stability when using the larger overdrive pulleys like the 15% pictured on the right of the pic.

I plan to run the 69mm Upper / 15% lower to start.

Here, we have some Zeitronix goodies that I purchased from Lund Racing.

I will be using this in conjunction with my Lund Racing NGAUGE to have all of my data in the logs from/with the ngauge.

Fuel Pressure
Oil Pressure
Boost Curve
EGTs
Additional Failsafe Wideband/AF

I plan on pushing things hard...so the more data the better!

Rey@Juggernaut Power hooked me up with a smoking deal on a set of these Borla Longtube headers. Tracking shows these being here Tomorrow.

I am not so sure the LT headers will improve the power and performance substantially, to be perfectly honest.

What they will do though, is make pushing more boost and nitrous a little more effective, and safer, etc. The less heat, the better!

The great folks over at Lethal Performance have a Reische 170 Stat coming my way.

http://www.lethalperformance.com/sh...mance-ford-50-170-performance-thermostat.html

Same with the headers, this is to make the combo more effective and safer at higher cylinder pressure levels.

Now that I am going to be pushing the car much harder, I went ahead and upgraded my rear tires. I took the MT II DR in 295/45 off, in favor of these sweet new MT "R" Radials, in a 305.

I went a 1.44 previously on the other tires, and suspect they can hold 1.30s...but I think these new tires will be much more consistent.

I also wanted to get a taller tire, so I can experiment with crossing the traps in 3rd gear ----(at 8500rpm)

Of all that said, I will be honest - my wife is starting to notice this stuff. I may have to slow it down temporarily.

I may pick her up a Ford Explorer EcoBoost (and tune it!) to hold her off for a bit.

More updates coming soon!!!!

Be sure to come to NMRA Bowling Green. It should be a great time.

Saturday night, I have a race lined up with the Watson Racing car.

Impressive stuff for sure! Love all the little touches/details/supporting parts. Not cutting any corners! Can't wait to finally see this up close soon.

 

[Scott8583]

Very Nice! :rockon:

I'd really like to find out how you like the new tires. I'd like to run 17's all around instead of Pro's in the rear... Wow 8500rpm! Is that HP tuning software? We can't get past 7600 with SCT on my car.

 

[Scott8583]

How about a update on your car now that BG has come and gone...

How do you like the new tires? What kind of 60' times? What kind of mph out of the 69mm & 15% lower pulleys?
I thought I seen a pic of your broken driveshaft, that sucks :/ was it from wheel hop?

I read on another forum that he broke his diff and then twisted his driveshat. Not sure if he got any clean passes, but they said he went 9.4 on one. He had a very busy time sourcing and replacing the diff then the driveshaft. Not a great weekend with all that and the horrible weather on top on it.

Update would be, first pass: snapped the differential housing immediately upon launching. Resulted in a bogging 1.40 sixty and 9.6@144

Second pass, snapped DS in half on the launch - car moved 3 ft and had to push it back off the track.

TRUE STREET PASSES - - Third pass with a cast iron diff, and stock 2-pc DS with a ton of timing pulled on the launch resulted in 1.57 sixty and 9.7@145

Fourth pass, still true street, same sixty...same ET and MPH.

No wheel hop. All passes hooked, no hop. Car works well.

I am addressing the issues and expect much better passes soon.

 

[Scott8583]

That sucks to hear about the carnage... Looking forward to seeing how far you can take this car!

I assume you like the new 305/45/17 R's?
I'd like to go 17's all around next year.

 

[BMR Tech]

I love them. A LOT.

lol

 

[ALLKHEINZ]

the 305/45/17's are kick azz i was able to cut 1.41 60' on my 17" Darkstars and 1.45 on 20's with the other new M/T Dr's 305/35/20 et street ss..these new tires from m/t sre working great.

What psi do you run at the track in the 20" M/T dr's?

 

[ALLKHEINZ]

What psi do you run at the track in the 20" M/T dr's?

i run the 305/35/20's at 17psi to start and go up or down from there....i do the same with the 305/45/17's

Do you think the Vi king shocks made a big difference with the 60fts ?

 

[ALLKHEINZ]

yes 100 % made a difference.

 

[try03venom]

Nice which of the two models do u run?

 

[ALLKHEINZ]

Nice which of the two models do u run?

i run the cheaper street/strip version but they are still double adjustable.

BMR Tech - We spoke awhile back about the differentials breaking the ears. (Dustin @ Archangel) You are far from the first to pop the ears off. I'm sorry I put the bad mojo on you by talking about it! I think we need to develop a brace? We can chat next time we have an order. Do you have any pics of the diff case?

Yeah, I am sure Ford / FRPP and maybe Roush likely experienced it. I mean, somehow Ford knew to put Iron in the stick shift cars - so they knew/know something.

I am not sure about a brace. At that point, I think an Iron housing with Billet Aluminum diff bushings (what I have now) may hold up to the task.

I am working on some stuff. Upgrades, to existing components per say.....but I am not going to let that cat out of the bag yet. There are eyes on us.

Time will tell. I havent seen anyone break the ears yet, and all but one of the fastest S550's thus far are my customers. I broke the ears before anyone I know, so let's see if I can be (publically) the first to break the Iron ears off with solid bushings. I hope I don't, but kinda hope I do. haha

If I have a failure with the current configuration, I am going to put in a G-Force 9" IRS Conversion.
