Broke A Piston Wrist Pin.

Its cool just funny to me! I see you got good dyno numbers, but I'm more curious to see if you can hook up at the track and put down numbers to match! My talon is coming along and soon will be a 600hp beast!! But I won't be satisfied till my e.t. Sig says 10.xx@1xx !

I feel what you are saying.

Have you ever ran the car yet or have any plans too?

Only ran it at Friday night drag grudge match 1/8 mile no clock. When I am finished with my setup I will get it to the track for sure. I've only had this gst for a year and been building this engine most of that time.

Man that was fast!! What did they express mail it! I thought it would not get here till next Thursday? Well you got it now is all that matters! Now for the fun!!! Is the Comp compressor wheel bigger or is this comp turbo bigger than the 6266 Kels? I already know the pte cea 6266 is a BEAST of a turbo.

That Comp is enormous. So Kel, have you had previous success with the comp turbos? Reliability-wise? Justin said they are junk, along with PTEs. I have no problems with close to 5k on my 5858 now and it JB but i do know if it fails its not worth fixing. They are very expensive to have rebuilt compared to other jb turbos.
Are comps the same in that regard?

The turbos are the same size the Comp Wheel is just bigger than their Pte 6266

I've heard that the PTE CEA turbos are a whole lot better than their (PTEs) JB turbo's.

I can't say anything about the Comp turbo's dont know anyrhing about them.

IMO based on my personal experience I don't think comp turbos are engineered for the dsm community it takes too much too spin them. You have to have a high reving Honda or a large displacement supra for them to work well. Comp has an excellent concept but I wasn't happy with any of the turbos from them. I dynoed 573 with the 6467 the problem with that is the turbo is rated hp close to 900hp disappointed. I am estimating that with this 6266 I should make somewhere around 630 to 650 wheel horsepower if this happens the smaller Pte 6266 CEA will make more horsepower than the larger 6467 comp turbo. Which leads to my point the 6266 CEA is better suited for my setup not to mention that my heart has been set on 6266 cea for quit a while!

Do I forsee a holset in your future?

I think this time PTE may have it together with these new cea bb units! :thumbup:

Sounds like the design of the turbine wheel might be made for high rpms or something, guess you need alot of exhaust velocity or flow to make the comps go I would assume. Or it may be the combo of the exh and compressor wheels that creates a velocity high flow situation just guessing.

It's not the turbo, it's the cyclone intake. A 64mm turbo is something you need to rev 10k to make power. A cyclone is all done by 6k. Not saying it can't be done, but it's a big missmatch, and you are forcing it to work instead of letting it work.

I tried to explain that to him. Its no magic to making power. 1 piece will not solve the entire HP puzzle. It's an art to it. It all comes down to the setup as a whole. It's about balance.

These^

Manifolds are tuned for RPM related N-Order harmonics. If you are looking for a record on a specific intake manifold.. you find a turbo/cam/displacement combo that can make your power goal in the rev-range that particular manifold shines at.

Conversely - If you are trying to max a compressor wheel, you need to build a combo that hits farthest to the right on the compressor map you can reach.. or even just off the right side but before the choke region.

You guys better delete your posts about the cyclone. The new 6266 turbo is on the car and all I have to say is WOW! I respect both of you but not on this one sorry. This turbo puts all the comp turbos I have own to shame at only 27psi! I will get some video footage soon!!

 

[LandSpeed-DSM]

Get as much air moving as possible before ~6.5 - 7k where it starts falling off and you'll be in business.

With a turbo you have temperature and pressure on your side, you just need to take advantage of the manifolds particular VE curve as it relates to 3rd Order Harmonics for that runner length. (~15")

Agree 100%. Bc 272 cyclone pte6266 imo balance look at the compressor wheel differences my car is finally making full boost around 4800rpm and pulls hard to 8500.
I I think that my horse power goals are modest not to mention doable with the cyclone 650 horsepower everything on my car was well thought out except the turbo when it comes to my goals.

Curious to see how it works out! My approach would probably have used something like a 1G (93-94 Turbo MT) factory intake cam straight up, HKS264 exhaust cam advanced 2-4* and the 6266 in a divided housing with the wastegates all but wired shut. Using E85 or E98 for added exhaust volume to bring the turbo up faster.

Yeah from the feel of it I am very curious myself.

Notice that I didn't say you couldn't make power with it, it will just be much harder. On my setup I bet I could make an easy 750 with the comp.

The 6266 is a much smaller turbo, so it's going to come on harder.
