Thread: HCR sr20de build dyno runs.

This thing is an absolute monster. Great work man. Keep it up, that is one hell of a motor.

very nice mid range, i say you gain a ton with the air fuel controller and the header... little more tweaking it will be even better. very nice rob

rob...this thing is increadible! i have a question tho. seeing this crazy power you are making has convinced me to go pretty much mod for mod with what you doing. however my engine build started as a basic rebuild to have a solid reliable engine with bolt ons. with the high compression and cams/over lap would you drive this car every day? including hot summer days? if not what would you change?

im planning on:
VE head gasket
pullies
intake spacers
BC 3 cams and springs
gears
SAFC 2

would you recomend the 10:1 pistons? sr16ve n1 pistons (coated) or 2.0vvl? feel free to call me up so we can talk. im off all day tomarrow.

^^ this is making me want to go N/A on one of the NX, if not get another SER and do it to that. Very tempting

......what the HELL is keo doing up at 4am, go to sleep old man.

I drive the car every day already. (except in the snow and when the ground is coated in road salt.) I haven't seen how it would do in the summer yet because the swap wasn't finished till winter. It has seem some 60 degree days but thats all. I don't think it will have any problems. 20VE pistons won't give you much of a compression bump. I'd stick with sr16ve pistons. I'll give you a call it'll probably be a slowass day at work.

wife woke me up cause she needed some

edit: i forgot to add that Rob's E would be a good canidate

Very Impressive Rob!!!

Tune that AFR to some nice 12.9:1 across and gain some more.

Actually interested to see if the 2.33" vs 2" SSAC secondary difference makes up for some Power.

I think giving it more overlap will kill the torque at high rpms, check the dyno files I sent you. Your Tq curve stays pretty fat till the end.

It seems like you / the operator hit the sample button before you hit redlight? Even if you set the graph properties from 2K to 8k rpm it might be cut at around 7k still... Tach might be off about 300 rpms, so 8000 tach would be 7700 dyno...

yup...only thing youll be working on is bent control arms

do you forsee any over heating issues in the summer? i meen 11.#:1 compression cant be any hotter than a turbo setup right?

well turbo setup utilize colder spark plugs along with a more rich fuel environment to stay safe, whereas sometimes most naturally aspired engines use more of a lean fuel condition to make power.
