This is still twin scroll there is a divider that travels to the wastegate flange. This has been done thousands of times with proven data all over the web. People knocked our top mount kits to when they first came out, said they would crack wouldn't perform etc look what those are doing. lol
Still have yet to find another 335 as fast as my off the shelve tune 335 60-130

well you could have just said there is a divider in the first place, then we wouldn't have this argument.

there is nothing wrong with the wastegate location on the turbine housing. the problem is that cutting a thick caste piece and welding a flange on top is still far from ideal. could have just used an IWG or something like this

this is a very interesting option, and deletes the weld. Do you have a link for this housing?

Jerry... would this be an option? seems like it would be easier for you.

This kit is gonna destroy 02 sensors ask me how I know I had to Re design my kit twice and even after that there only lasting a few months. I have the identical manifold I released in December. Be warned you will be buying 02s weekly the way he designed it.

I already have Venturi style heat sinks. Been running it that way for a couple months the first thing I figured out and fixed. The photo you posted didn’t have them. So good job! Point is they still don’t last. wide band sensors can’t take the back pressure and temp of the twin scroll log mani. I’m gonna try adv sensors and let you know how that goes. Not sure why your so pissed this is a technical post.

Oh i am not pissed at all... i find it funny that you hashtag jpworks on your ig, write me personal messages on ig and then write on all theads that have to do with my bottom mount. Your swinging pretty hard if you ask me. I had no clue about your company until you send me those messages.

I contacted you because I had a ton of people saying hey look this guy has your exact same manifold! I was shocked but really don’t care anymore man. I am wasting a lot of time on here. But I am honest and not afraid to speak the truth.

I like to see any kit put up some sort of numbers before I could even begin to endorse or recommend anything. This is one of about 4 kits I know of coming in for sale under 4k supposedly.

Is this your design?

What is this a joke?

I looked some history and I saw this...LOL
bet you sold out on these?

Group urinal plumbing?

To break it down quick and easy. I put down a deposited for top mount, then paid in full when Jerry asked for full payment, and waited exactly a year before I decided to do a chargeback with my credit card. Had good communication with him until full amount was paid then there was none after that.

I will have one installed on my 135 with a 6870 before the end of February should be able to take down my old 60-130 and get it to no fly zone. Should have dyno numbers in a couple of weeks have to finish a few cars here before i can touch my own.

Jerry, please do yourself a favor and install this on a car and put up some data. Prove everyone wrong. Good luck man. Can’t wait!
