I know there is the stock shortblock thread but why not a dedicated 11r thread?

408,000 km stock short-block
11R190's 56cc
custom cam
ported systemax
75mm tb,? pro-m 80mm calibrated to 24lbers
untuned. 414rwho on a 125 shot at 3500' elevation
7.8@ around 90mph in the eighth at 6500' elevation track

Car ran about the same time in the eighth with the new top end mentioned above, as it did with the stock motor with longtube headers on a 125 shot, so I am very pleased to say the least.

112K stock bottom end 302

TFS track heat upper / lower - unported
Shorty headers
stock TB

270 RWHP / 290 RWTQ on a Mustang dyno
13.4 @ 106

I don't really know what's wrong with it, it should be a good bit faster than it is.

I have a converted carburetor intake in the garage waiting to go on, along with an accufab 90 MM throttle body. I'm just waiting for 6061.com to get the throttle body elbow to me. I'm hoping that picks it up some.

take this for what it's worth but here's what I see.
#1. The intake tract wants to be BIG. 95mm MAF, 3.5" pipe, 80-90mm TB. Not sure how it will like the converted carb intake but it should be better than the track heat. I like a holley SMII on a setup like yours. Try to think of it as a giant taper all the way to the valve. If you have a 3" inlet, a 2" restriction, and then 3" after that...what does that do to the airflow?
#2. The headers aren't helping but they aren't killing you either...
#3. That T56 hurts you. I bet you dyno higher and go faster at the track with a T-5 (gforce/asto)

Lastly, at 106 mph, you should go 12's. You need to figure out how to get it to work in the first 100' of the track.

One last question...how heavy is the car?
 
#33 ·
What combustion chamber did you get when you ordered your 11R's neat?
 
#34 ·
56 cc

Stock throttle body and shorties need to go.
I have an accufab 90 for it, waiting on an intake elbow.

Obviously the unequal length BBK shorties aren't helping, but I am wondering if the mufflers are stopped up or something. I might try unhooking the H-pipe the next time I'm at the track.

The car is 3090 without me.

It has a 90 mm mass air on it with 3 inch intake plumbing now.

Why do you think the T56 slows the car down?
 
#38 ·
This is one of the things I talked about. You have a 3.5" opening (good) 3" tubing (ok), and a 2.3" throttle body opening with a blade in the middle, and then likely a 3 to 3.25" opening after it as it enters the intake.

You're killing the airflow.

The T56 is heavier and will be more parasitic. It's just nature of the beast.

3090 without you...how much are you? That's heavy.....
Just for comparison purpose, tripleblackvert on here has a stock bottom end, TW headed engine and has been 122 mph (high 10's). His car is 2780 WITH him in it.

These little engines really respond to weight. That's how my little NA, pump gas 363 goes 9's. It's in a LIGHT car ;)

I'll be the first to admit that I'm a poor driver, so that hurts the ET I'm getting. The MPH is what concerns me, I figured the car would be good for at least 110, maybe even 112 or more.

I saw where another guy made 336 or so on a mustang dyno (65 more than me) and he only trapped 109, so maybe I'm expecting too much out of my car.

I'm 185 lbs.

I haven't done anything to the car to lighten it up; I actually put about 60 lbs of sound deadener in the car. The car still has AC and everything. It's just a daily driver type street car, nothing fancy. It also has the T56 in it, which probably added close to 100 lbs.

Thanks for the tips, I'll report back once I get the new intake manifold, elbow, and TB on the car.

I'm not suggesting you go gutting or cutting your car apart. Nice clean daily drivers with AC are GREAT cars.

Just keep weight in mind when comparing your car to others. There's a big difference between a 300 rwhp engine in a 3300 lb car and the same engine in a 2800 lb car.
