Im sorry i only got to watch some of the video but do they mention boost/pulley ratio? I believe Rick ran a 3.0 and 4lb lower with his 2.3 which should be probably 20 to 21psi. If they're seeing these gains at the same boost ill be happy. I think most of us wanting a 2.65 plan to push them harder than our old 2.3s and thats where the extra displacement will help.

Also Ricks car made 730+ when they were testing the gt500 tb on the 2.3. I assume its the same dyno, so i wonder why he's down 20+ hp, heat soak?

Rick told me that they were shooting for the same boost pressure. This was before they had installed it, but I believe he said 3.3/4lb lower on the 2.65

Didn’t they say in the video that the intercooler is
A huge restriction? But have 2.9 Whipple’s had the same issue in 20-22 PSI?

I don’t get that either. Didn’t they say that this blower was gonna be more efficient and have lower IATs than the gen 1 and 2?

How is it that IATs are a concern now, on lower boost.

Different day, different conditions.

If so then one could say that on the right day, his car would do 780.... 730rwhp + 50rwhp for the 2.65. I think ill be satisfied, gives me a chance to install intercooler mod get and fix iat2 sensor placement, plus hopefully make an extra 50rwhp. Ill call that a win.

Do the Whipple 2.9s suffer from the same heat soak issues? I find it odd we keep hearing how efficient this blower is now heat is a huge concern. No doubt the Cobra intercooler is small but I haven't heard of the 2.9s suffering from heat soak. This would worry me a little considering on the street and the track the car will be even hotter especially when doing pulls 1-4. Fact is the car needs a larger intercooler, anyone see how big the intercoolers are on the coyote 2.9s or even the new 3.0 for the 18s, things are monsters. Sorry I keep comparing these set ups to coyotes but crazy how much blowers have evolved.

Malcolm had a 2.9 crusher and he said it produced insane amounts of heat. This blew me away because I'd always heard a big blower is more efficient so they will produce less heat than a small blower. As always Malcolm has done lots of testing and now that he tunes cars sees a lot of logs. He's told me big blower cars with j2fab intercooler setups can run with minimal iat2 gains.

That last part do you mean the j2fab intercooler setup makes a big enough difference that there is a minimal rise in iat 2 temps with big blower cars?
Or that even with the j2fab setup the iat 2 temps are a problem?
Sorry been one of those days and I’m reading your comment both ways.
Thanks

And those are STD uncorrected numbers.

STD is not uncorrected numbers. They are inflated numbers. SAE, which is J1349, is considered the most accurate correction in the industry is what people use to compare numbers. STD is J607 and is a correction that reads higher.

Ken,

With Justin's setup and a good pump there are no IAT2 issues.

Theres no way heat soak should be an issue for one single, clean run, and on an E85 tune no less. It's not pulling timing until mega high IAT2 temps. The car can cool down as long as they want on the rollers before a pull. If it is hitting 175+ IAT2 after a single pull on a cooled down car, that is alarming. So then you start questioning that sensor depth issue like the 2.3 has, and maybe this one is worse. Who knows. They need to post the data temps from the log

Or, there could be an issue with this car. Thats the reason another one needs to be tested. I'm surprised they're shipping these units out this week and don't have a single clean dyno run before hand.

A GT500 owner posted his car gaining 80+ RWHP on his GT500 at 18psi with the same timing, same boost the only difference being a swap from a 2.3l to a 2.65. That was proof enough for me, its hard to think the Cobra version could be "screwed" up enough to not provide similar gains, its the same blower with just the inlet on the opposite side. Time will tell.

So SAE numbers would be in the 720/685 range give or take. Looks about right for the setup. I was thinking a pretty high end maxed out setup would hit 735/700 SAE short of high compression and maxed heads/cubes.

You will not see many hitting 800rw. Remember the 2.8L and 2.9L are more efficient technology than the TVS. Look how many of them are actually hit 800+rw SAE.

I hope I am dead wrong and this time next year everyone has 900rwhp on 18psi cars but the amount of air a 2.6L moves is just not enough on our engines with out a lot of help.

This is a badass blower, it has made over 1000whp on both Coyotes and GT500s boost only. There is no reason why it will not do so on a Terminator once turned up. This compressor is moving a fixed amount of air per revolution. The amount of air compressor can move is hardly dependent on the motor. A smaller less efficient motor will see higher boost pressures.

I think the inlet for the Cobras are restricted in comparison to the coyotes and GT500’s. They mentioned this during the video. They didn’t want to run into fitment issues since we have a cramped bay in comparison. Can’t have it all.
