BMR Racer, SST Champ Chad Wendel Making 300HP WORK!

[GT.350-R]

So, we need Chad to go 11.78.

Chad, put your man pants on....and raise the limiter to 7800.....

The limiter is at 7800 already.
And, what's this coyote swap you speak of ;-)

What are you shifting at?

We have a little more "aggressive" tune to load in the car, but need to test with it before using it at an NMRA event. Just need to find time to meet up with Chad, get his car to the local track and let her rip... We tried testing with it at Milan in the fall but wanted to run 11's with the setup he has now. So MIR might be very interesting if we get some testing done.....

What are you shifting at?

7000

 

[2DaDarkZide PR]

7000

No issues as of yet?

 

[2DaDarkZide PR]

1.49 60' on Tockico adjustable D-specs..Set them loose for the strip then tighten them back up for the street.. They work great

Hmmm,

 

[GT.350-R]

Not yet.
This tune has been in the car for 3 years.
Works great every pass and drives perfect on the street.
It's worth the $75 bucks if ya want to try it.

You never hear the end of not shifting after 6800 but I see more and more people doing it.

 

[NotQuik]

I forgot you were spinning it that high...when making the last pass at the track I happened to look down and noticed I was shifting at about 58-6000 (I used to aim for about 6200 but i'm still rusty in the driver seat).

I wonder what some of the other guys in the 11's with stock 3v's were shifting at?

 

[fdjizm]

6500 is a popular choice, and makes sense when you see what rpm you end up in the next gear.

 

[Matt D]

I use to shift at 6600-6700. Like Fdjizm mentioned it's all about where the needle falls after the shift.

 

[GT.350-R]

I've tryed it at different rpm's and 6900 to 7000 is where it ETs the best.
I drive by the seat of my pants, so I shift when my ass tells me to. LOL
Hell, maybe my Tach is off a little.

 

[fdjizm]

I might try going higher!, for further explanation I made this a while back. shows how short shifting can mess with your ET... I still hear people talking about "you don't make power up there why are you shifting that high" lol.

this is specific to my car and my power curve, results may vary.
rpm in the NEXT gear is very important!

 

[BMR Tech]

A lot of people don't analyze this stuff (proper shift points)

I have learned over the years on these type of combos, that the best ET and MPH usually comes from gradual decrease in shift points. For example, 7,000 1-2 shift, 6700 2-3 shift, and 6400 3-4 shift.

You can work the numbers, and place the next gear right at your peak TQ RPM.....

In your 6500 shift plot, if you shifted 3-4 at say 6000, you would probably gain 1-2 mph on your timeslip.

 

[fdjizm]

I noticed that too, the gears are very close together.
I really think I should shift 3-4 at 6000 so it falls back into the torque range.

I was about to ask Chad if he shifted at any less RPM for 3-4 too lol.

How does this one look?

 

[Mike K]

I go through the traps in 3rd at about 6600. I shift about 67-68 those 2 shifts I do.

 

[ArtQ]

Shift mine at 6800 and cross the stripe at 6800. Its had more than a few excrsions to 7200. Tore the engine down a few days agofor some upgrades. After 5 years over 1000 track runs it looked like a brand new engine inside. Bearings were perfect. Ford did a hell of a job on these engines.

I am pretty sure I told Chad to try this, and he said it didn't work for him.....but I don't remember.

It has always worked for me. My last N/A car went 11.50's@118 with 340hp, and I used this method (gradual decrease in shifts)

It was a different set-up than the ones we are talking about, but the power curve was shaped similar, and I had 4.56 gears.

 

[2DaDarkZide PR]

This is VERY interesting.

I have 4.10s and 305/35R18 on 18x10 wheels.

Here is my dyno. What would you BMR and FDjzm recommend as something to try

I am always open new ideas. ESPECIALLY when people do more with far less than I have hehe.

 

[fdjizm]

Your HP barely falls off near 7k and 4500-5100 rpm is your chunky torque area.
3-4 should be like 6300 or so to fall back into that area.

I'd go...
1-2: 6800-7000
2-3: 6800
3-4: 6300
