3rd gear it's a bit higher in 4th given load and all but for all practical reasons that's where I saw that boost level. Regardless it's up and going very soon.

i have watched a local gt35r/35 40 3rd gen dyno at basically a bar and he had full boost onthe dyno right before 3500 and it held rock solid boost till he let off.

i only asked which gear cuz you can typically spool turbos faster at higher gears..... and i always get confused by people saying it boost to certain boost levels at certain rpms.....



like my twins, i could spool it up to full boost at 2300rpm, but that would be in 5th gear... lol

It's cool. Like I said that's what I remember it's been a few months since I've been able to get it out.

Well the most I plan to run this turbo to would probably be 19 psi or so on race gas and I was told this turbo really doesn't become efficient on our motors until about 17psi. But that just may be a difference in opinions. I don't know really but I've heard both sides of that argument before.

I ran the 35/40 for over a year and got tired of it. Yea I put down 430 @ 16 psi and 470 @ 20psi but the timing was too advanced in my opinion. At the time the ports I had which were supposed to be huge, were garbage. After properly porting the motor and getting tuned by Steve, I never had a chance to dyno again. Something is messed up with the turbo. Steve thinks its the compressor map or something. It would make 15psi by 3500 rpm, but wouldn't pull hard till 6000. By 7500 power was falling off. Its good for the street, but I am looking for something more. All it took is a ride in a properly set up 60-1 car to convice me to sell the garrett.

This was essentially the feedback I got before buying my 42. This was from someone who installed both turbos back to back on nearly identical cars. Something just didn't fell quite "right" https://www.nopistons.com/forums/pub...1047683561.gif

how's your new setup coming along?



can you start a thread with the details.... or message me? cuz im in the market for a single

I'm now interested to see if the same is said about the 40r once a few more people have bought them and gotten them tuned properly. I guess we'll just have to wait and see.

This is why I was reccomending the T04e or s Dave.
