homemadeturbos suck?? wha'what??--now w/ dyno graph
 

spent some quality time w/ charles today at mainstream performance in powdersprings, ga (suburb of atl). i installed my new intercooler and changed oil while he was getting another car ready for me to tune. when i got his car done i finally spent some quality time on the sohc non-vtec homemadeturbo.

203whp/199wtq SOHC POWA' b#tches!!!!

not too shabby from it's humble beginnings of 85-90whp bone stock. today was hot and humid...overall i'm pretty happy w/ the numbers. ordering traction bars next week.

i forgot to print out the graph...i'll post it up when i can get it from charles' computer.

now i gotta get off my a## and build it up for the other turbo and up to 22psi.

Re: homemadeturbos suck?? wha'what??
 

---- tune my y7 to that !!

Re: homemadeturbos suck?? wha'what??
 

if you're willing to come to atlanta...c'mon!!!

Re: homemadeturbos suck?? wha'what??
 

how much psi were you at?

Re: homemadeturbos suck?? wha'what??
 

it would spike to 12psi at the lower midrange and settle down towards 10psi from midrange to the topend. i need to get an ebc instead of my manual boost controller. i've never had much trouble with it not holding, but i couldn't keep it steady yesterday.

Re: homemadeturbos suck?? wha'what??
 

Any dyno plots you can post, i love y7 powerbands, especially their torque. ^-^

Re: homemadeturbos suck?? wha'what??
 

What intercooler did you install?
Is this still using the TD04 turbo?

Re: homemadeturbos suck?? wha'what??
 

i installed my anodized black jrc replacing my old starion. fills the mouth of the bumper perfectly and is way more subtle. this is still on the tdo4L/13g.

new setup is in the works...here is a little preview:
eagle h-beams
srp pistons
a little headwork
motorolla 2.5 bar mapsensor
t3 60 trim .48 turbine .60 comp

i'm waiting on an excuse/reason to get started.

Re: homemadeturbos suck?? wha'what??
 

hopefully by tuesday...mainstream is closed mondays. i'll post it up as soon as i can get my hands on it. i was so tired from the heat and humidity i wasn't thinking of getting the printout.

Re: homemadeturbos suck?? wha'what??
 

Ya man those are som impressive numbers. Thats what im hoping my setup is around.

Re: homemadeturbos suck?? wha'what??
 

Not bad at all. I want my y8 to get 200whp too off my T3 .48/.63. I don't think I'll boost to 12psi though. 10psi for the track and 7psi-8psi around town. I'm going to run stock internals so that size turbo on my y8 boosted to 10psi should hold, right? I want to see the dyno, too. ;) ;D P.S. I like!!!

congrats scotty, your new motor setup sounds alot like what ive been planning on doing also. maybe we should do a twin buildup... vtec vs. non-vtec :)

Re: homemadeturbos suck?? wha'what??
 

i'm going to the shop tomorrow night...i'll post up the graph as soon as i get home.

checked my email and there was a present waiting. thanks for emailing the files charles.

if the boost wouldn't creep back to 10 from 12 i could've been in the 210's to 220 range.

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

whats with the AFR's? graph looks like its all 13's range.

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

it's aggressive in the low end...13:1 while it's transitioning. 12.5:1 to just above 12:1 full boost throughout midrange to upper end. i've run this engine tuned similarly to this for almost 2 years.

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

ok so the dyno is probably just using a sniffer which tends to be about 1/2 point off.

more than likely yeah, sniffer's just reading a little lean, i hate those damn things >:( tune looks real good though man, good job!

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

it's in the downpipe...12.7 at 3.5krpms 12.5 at 4krps and 12.2 at the topend. it's hard to tell because i didn't put the red indicator line at 13 across the af graph. i may work on the mbc tonight to see if i can get it to hold.

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

yikes, a hair lean for my taste :-[ i try to keep afr's right under 12 anything over 7 psi, the .5 more fuel won't affect the power at all, and it's just al ittle extra insurance, for say a less than perfect tank of gas or some warmer charge temps on a hot day, etc. but too each his own.

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

when i do customer's cars i'm not that aggressive, but it did make more power than being richer than 12:1. i tend to be conservative like you on customers cars, but if i blow my own it's no big deal. i've got everything to rebuild right now (eagle h-beams, srp pistons, arp headstuds, 2.5bar mapsensor, bigger turbo). it'll just give me an excuse to get started, however, it's been tuned to afr like that for over 2 years. ;D

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

So does it pull strong as ---- or what ;D

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

oh yeah, a whopping 200whp, i'd imagine he can't keep it between the paint :P

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

I had similar numbers with my 13g setup.Nice work.

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

Damn man, nice numbers. Makes me wish I would have gone with that 13g instead of my T25.

Re: homemadeturbos suck?? wha'what??
 

yeah, i got that intercooler, i love it!

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

Oh common ;D
It should pull pretty hard :-*

Before you install the T3 you should do me a favor and see what the max power you can make using the 13G.

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

damn dude your always an inspiration!! i can't wait. literally 3 more days until i can begin installing my wrx snail


congrats on the numbers

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

Are you using an oil restrictor?
Any chance we could get some under the hood photos?

Re: homemadeturbos suck?? wha'what??--now w/ dyno graph
 

no oil restrictor...i'll have to get some updated pics. there are some pics in the link in my sig.
