my new 2.4 gt4088r build (with dyno sheet)

[killercolt]

please get that new daily driver you are talking about so we can turn up the boost. don't let me build my high compression 2.4l and beat you to the punch. you know i already have the gt40r sitting in my kitchen.

Thanks to every one with the nice replies. i know that i have not been on line in a while, i have been busy with holidays and work. I am starting to work on the small list of problems i want to sort out before retuning. I am going to start a new thread on it because i am stumped. i will link to it here once i write it. maybe you guys can help

1. I have no speedometer on the dash with the aem

2. The tachometer does not work properly, however works fine in the aem

3. I cannot for the life of me figure out how to reprogram my innovative wide band for a second 0-5volt wide band out put. the default configuration is one wide band 0-5 and, a second 0-1 narrow band. i need the second wide band to do o2 feed back to the ecu.

here is the link to that thread if anyone has a clue on what to do? A few AEM EMS problems

Congratulations man. I am very glad to see people interested in the question of high compression with E85.

Wow! That is a ton of power for 20 pounds! Im pretty sure if you get it up around 30-35 pounds you'll be over your 700whp mark. A guy I cruse with has an AWD spyder with a 2.4 stroker and a gt42r and he makes about 675whp on a conservative pump gas tune. He did tune it e85 once and get around 815whp but that car spools fairly slow. If he doesnt hit 2step, my buddys 275whp 16g car rapes it till about 60mph lol

And that guy you speak of might be the infamous Mario Lopez?

yeah, there has been a lot of back and fourth about high compression on these boards. I really wanted this build to show what you can do if you optimize efficiency of the fuel in this case e-85. I have definitely caught my fair share of flack from people telling me there is nothing to gain and it is not worth it. The only down side i have seen so far is the lower torque and slightly lower spool then i was expecting. that being said without running lots of boost down low it is to be expected. for example: when you run 40PSI your waste gate is closed completely until probably about 36 psi. (this is just a example so please don't take it as truth since i do not have real numbers) which is 4 psi from target. were as when i only run 19 psi my waste gate starts to open at 15 psi. so it causes it to spool a little slower. since as all of us know it is much quicker to go from 20 psi to 30 psi than 0 psi to 20 psi. basically in a nut shell all i am trying to say is if i was running 30 psi it would spool probably faster than it does now or at least the same. but i love the increase in efficiency in the system from not having to run all that boost to make a good number.

I will be back from Japan Sunday. Hope you are ready to turn the boost up. Hope you got the Nitrous Express kit installed too. Screw the tach and speedo for now. Those will be easy to fix. We want to see 800hp and 650tq. 35psi and 125shots remember? Now that you got your daily driver, we want to see that car destroy some tranny parts.

^^^Yes please!!

thank you killer colt, encouraging as always. Remember i still want to drive the car a little before we blow it up.

as for more boost.. yes please

i pulled a motor out of a 92 expo van which is a 4g64 6 bolt motor

quick update. it looks like the standard arp head studs cannot survive in this power range.. i have a new head gasket and map h11 extreme duty studs to replace it with. also the motor has about 100 miles on it and has finished sealing up and is now very lean from the original tune. this leads me to believe that the motor will make a lot more power on the same boost as last time.

that motor is sex... FINALLY someone with high compression.. im next on the list

thank you for the kind words.

if your engine is really 13:1... which it looks like the pistons are maybe -3cc.. which should put you over 12.. then i feel like a wuss only going 11:1... granted the pistons i have are custom manley's that i bought brand new for 400... cant argue about that.. also im going with an aluminum rod..so...one thing.. do you know how much your pistons weigh?
