upgraded to a Super cobra jet mono blade throttle body

This is interesting, Van. So is there any reason why somebody would want to go with a dual 65mm over the mono blade? If the drivability is perfect with the mono blade and it makes more power, it seems like a no brainer to go with that one over the dual 65mm. I would think there has to be a catch going with the mono blade. Is there a catch?

No catch really. Many of my customers choose the dual 65 strictly because the empirical data shows that it has excellent drivability over and over. The Mono Blade has excellent drivability as well but the slimmest chance of any sort of issue from the mono blade steers most toward the dual 65. Ultimately it's simply up to the end user and what they want. I keep both on the shelf all the time.

Okay, cool I had a feeling that's what it was.

I have a Bob Kurgan tune with my setup which includes the FRPP mono as well. I notice a slight bit of wanting to surge. It has been magnified since changing out my gears to 4.10s, but it's been tolerable. Overall I'm happy though.

That's what's crazy about mine, it doesn't surge at all, its smooth as glass. I must have gotten a new model mono blade.

Have been running a mono-blade on my 11 since 2/27/2012, no issues.

Because I never had any issues, one went on my 14 as well..

Also have been considering this swap, has anyone have dyno results before and after?

With the FRPP Oval Throttle Body on a 13/14 GT500 any of them made February 2014 or later are good to go. We discovered intermittent issues with the FRPP Oval that were made pre-February 2014. So if you looking for new or used make sure you have the correct date!

Just as another point of reference, I have run the FRPP Oval Throttle Body on my 2014 GT500 convertible mated to a Whipple 123MM CAI with no issues whatsoever for over a year and have experienced perfect street drivability and manners. Tasca Modshop installed the parts and provided a custom Tasca dyno tune. Of note, my FRPP monoblade was installed back on 10/2013. I am not disputing anything Van stated nor anyone else's experience. I simply wanted to provide some direct evidence as someone who has had zero issues with a FRPP oval throttle body. Dyno tune results from this performance configuration was 760RWHP (~870 crank HP) and 660 lb.ft. of torque.

On a different note, I received my GT500 back from Tasca Modshop on 3/21/2015 from it's latest set of modifications. Specifically, I had installed Kooks 1-7/8-inch headers mated to a Kooks "Green" catted hi-flow H pipe (I know, I know - my engine will self destruct from a failure of the aftermarket cats and I am a complete idiot), a 3.75-inch (smaller - standard is 4.00-inch) supercharger pulley on my 4.0L Whipple, a 168MM Whipple monoblade throttle body mated to a JLT Super Big Air 155MM CAI, and a new custom Tasca dyno tune to handle this new performance configuration. Output was 842RWHP (~960 crank HP) and 750 lb.ft. of torque.

The weather in Central New York is still crappy (it snowed yesterday and today - for crying out loud even us Central New Yorkers toughened-weather folks are crying "Foul"), so I haven't been able to take it for a cruise. It idles perfectly well if that counts for anything.

This is in the "for what it is worth" column.

Sounds like a impressive build, so your making 842whp, on a stock 5.8?

Yes, my engine is a stock 5.8. I have added a few items such as a JMS 1000 BAP (but retained the stock injectors and fuel rails); a Shelby Extreme radiator (C&R makes it); a Shelby Competition HE with dual 11-inch SPAL fans (C&R makes this as well); and a Bob's Ultimate oil separator which is firewall mounted. Everything else engine-wise is stock.

Wow, that's impressive! I thought the stock pistons were only good up to about 800rwhp?

Please becareful and good luck. As you already know you're playing in the danger zone.

It depends upon how one drives their car. Drag racing and constant power hits to the engine, and it won't last long. Taking care on the RPM levels, not dragging the car and not constant WOT, etc. and the engine should last a long time. From what I can gather, I am a rather unusual GT500 owner/driver with my staid driving habits, and because of these driving traits I am comfortable on where the power levels are with a stock engine. I fully understand that with any performance modifications, the engine could let go tomorrow, but I have a reasonable expectation that it will stay together based upon the above.

I trust my tuner (Tasca Modshop) and they gave me the limits of driving the car with longevity in mind. The car should have excellent street drivability as before, and I am at the top limits of the stock engine. Anything more would require a built engine, and this met my goal (e.g. taking it to the limit without removing and building the engine). Correspondingly, I won't be adding anything additional to the engine in the future.

Sounds like a monster, I have the Shelby compition heat exchanger also, It's definitely a great unit. What RPM are you shifting at? Can you post some engine pics.

Don't laugh ... I have no idea, but it isn't anywhere near red line (which, by the way, has been lowered by this latest modification from 7000RPM to 6400RPM). The following engine picture shows the previous 4.00-inch pulley versus my new 3.75-inch pulley, and also shows my previous FRPP Oval Throttle Body and 123MM Whipple CAI and not my new Whipple Big Bore Elliptical Throttle Body and JLT Super Big Air CF CAI.

Damn that awesome looking engine bay, ya 6,400 is safe, I shift my car at 6,400 rpms also.

Nobody will laugh with those results.
Awesome looking combo and results.

I'd agree with casual use and respecting the octane and rev-limiter, the stock bottom end may surprise you...or go tomorrow

Obviously hope not but that's the game right?

So, Whipple 168 and KB 168 but Accufab doesn't make the KB, would be interesting to see who does?
I'm sure there both capable, would just be an odd coincidence they both choose 168 unless its a common dimension to keep.

I know this is an old thread,but I have had NO issues with Lund tune for 65mm CJ swap to SCJ mono.Idles perfect,driveability is like stock and pulls like hell.Don't fear the mono..i wish I didn't start with the dual 65 but it came with my Whipple.

That's great to hear. Lund is the man for tuning the mono blades. I would never let anyone else ever tune my car but him. I can't say enough good things about him. It's kinda funny my old thread popped back up again. I just upgraded to the kenne bell 168mm mono blade throttle body and of course Lund has it dialed in, I wish I had never started off the any of the twin blade throttle bodys. The mono blades just work better for performance IMO.

I hate to bump this old topic but I’m looking to buy a used mono blade and I see a mention of build dates, is that stamped on the throttle body somewhere?
