How are you controlling boost now? I am going to go with ECU controlled boost because it seems to work great if you can get it done right. That and you get to change the boost per RPM so you can start out low and in 2nd-5th be full boost. The people that are using it says that it doesn't taper at all, then again it is at sea level but the ECU does help the boost maintain.

And DB's Bad Bish is what sold me on the hta86 and only BR parts. That and the fact that he tells everyone when something happens and doesn't hold anything back.

With a 1.19 CF you are around the 625 range and that is good at this altitude with "low" boost, 35psi. There is one in Abq that made 69x at 30psi with a 4088 and a CF or 1.22, IIRC. He broke his transmission, then I hear he broke again, and again. He hasn't been heard from in 2 years. Another one made 720ish with the same hta86, he supposedly ran a 10.2 with no proof and broke. He has a 2.3l. I haven't heard anything about him in about a year either. Everyone in Abq thinks that an Evo with any kind of high hp can't and doesn't last longer than a few months. I want to prove them wrong and you seem to have proven them wrong. Another thing is we don't have a "good" shop here. You guys have Tobz and Jacks transmissions. I am thinking about moving back up there because of that lol

 

Hallman Pro right now. I do have AEM EMS that can also control the boost but I heard thats a bltch to setup so I was going to try the Turbosmart EBC route. What I like about the external EBC is I can easily raise or lower it if needed and won't need my laptop. Sometimes I have to fuel up on winter blend E85 and I'd rather run a lower boost for engine safety. Many high end turbo drag cars (ie- turbo Mustangs) are running the Turbosmart EBC with over 40psi and having no issues.

 

The Turbosmart is a nice looking unit, I know Al from Dynoflash likes it a lot.

I recently just bought a solution to bringing my laptop with me everywhere lol. I bought one for my saab to try it out and then I am getting the same thing for my Evo. It is a bit over kill but I love it. I bought a MitxPC with a 7'' touch screen monitor. I am installing it in my Saab this week and installing it in my Evo after that. I hated that fact that my laptop would go flying to the floor board if I had to hit my brakes hard or going hard into a corner.

 

Trust me, my Evo has been through hell and I think on its 3rd engine. Previous owner did a couple mistakes but managed 10.2 @ 139 with nitrous and 10.5 @ 135 without nitrous. I changed a few things after buying the car a year ago such as the turbo, manifold, heads, cams. Don't forget about Carz, Revolution and Mac for AWD dynos and tuning. Definitely a bunch a good smart people here in Denver.

I thought about a doing a carputer since I have the Orbital waiting to be installed but I do have a tiny Acer netbook that worked great until I tried to upgrade the memory and broke the keyboard connector so I'm back to my larger Dell for now... The small Acer fits in the glovebox and is under 300.

Sorry to get off topic Dennis.

 

That sucks, I was thinking about buying one of those tiny notebooks too. I have a son now so putting a movie on is easier with a carputer than a dvd player or regular radio.

Yeah, sorry about the off topic Dennis.

 

It happens, I figured out which turbo I'm getting... Thanks again Shawn!

 

Keep us high altitude guys informed with this comp T4 64 TBB Ex Tip with the .63 Tial V-band inlet. I am really looking forward to your results and if the turbo lasts a long time.

Good Luck

 

I didn't know you were throwing out "joyrides" , I am indeed in on the next go around. Bad *** car Rodent.

 

750 thats too much for the street im running same turbo, and i love that bisz

 

I let him drive since I'm so paranoid of getting a 12 pointer these days (especially after I got busted a month ago for doing that 50ft burnout) plus he was trying to decide on what turbo to get. I'll let you take it for a spin.

 

cause a 6262 bolts right up to a stock turbo flanged manifold by the time your all said and done a big turbo costs more then a stock replacement

 

Jealous...

I wish I knew ppl with more than 300hp

 

NO 2.4L SHOULD EVER REV TO 9K! Just because David revs it out to 9k one time doesn't mean by any streach of reality that it is reliable or benificial at best. Because guess what, it is neither! Have you seen any posts of David revving to 9k recently? No, wonder why. Maybe cause he lost his motor and knowing David he won't bring it up nor talk about it... What about AWDs 2.4 that they took to 9k... Seen anything on that recently either? No, and you wont! Just food for thought.

Here is some calculations that R/TErnie did. Eye Candy:

Stroke - Load 1 - Load 2 - Load 3
100mm - 7892 RPM - 8285 RPM -8746 RPM
94mm - 8219 RPM - 8629 RPM - 9108 RPM
88mm - 8573 RPM - 9000 RPM - 9500 RPM

Aaron at ER and I have the best 2.4L to date ever made and we both have a 156mm rod. We will never think of taking it to 9k, second off your piston speed above 8285 becomes faster than F1 piston speeds. Not to mention that 9k in a 2.4 is the same amount of stress as revving a 2.0 to to 9.8k. Not a smart idea if you want a motor that will last. But what do I know, everyone can do what they want!!!

The OP already has a Red so it is only 750 for him to upgrade to a Black. Robert is now doing upgrades.

OP: I think going to the Black would be your best choice. You can get 650/600 on a built motor on 34-36psi daily if you have a good setup. No need in spending so much money when you can have the same power for 750 with better spool...

Agree on all points. The GSC 2.2L seems to be a good choice and actually I thank the OP for raising the question a few months ago. I was originally sold on a 2.3L and just upgrade the tranny and final gear but since you can rev a 2.2L to 9k(as per Greg @ GSC) that should be even better. The tq of a 2.3 the rev power of a 2.0. And with Rob taking Red's to be upgraded to Black's next spring should be fun toss some meth ontop of the 93oct....I might have to buy a triple disk clutch

 

it seem like that turbo is lagging coming to life at 5k I don't think i would enjoy that on the street
