Stef's 7AFTE Tech/Project, First Dyno run pg16 Options

[hurley97]

As many of you know I'm going to turbo the 7A.


So first things first, with the help of Garrett's Turbo Tech 103 (Expert), I did the compressor flow map calculations... try to follow along, if you have any questions just ask...

here are the EQUATIONS:


and the CALCULATIONS (for a 7AFE with a target of 200hp at the flywheel):


then you need to plot some numbers on the COMPRESSOR FLOW MAP of your choice
I got a small Garrett 2052 which should be enough for my goals


From just looking at different compressor flow maps you'll learn a lot. In general, the closer the turbine and exhaust housing sizes the wider your power range will be but the maximum boost level is limited. When the sizes are significantly different you'll notice the compressor map will look taller and thinner, that gives you a smaller RPM range you can boost in but you can achieve higher boost levels in that range.

nice nice stef!!

what are you going to use for an IC, mine might be going soon

Looking good, witchhunter does a great job with injectors. They did my 460's. Great work and a great price, love the flow chart they send with the cleaned ones.

awesome, is some sorta step cousin way I contributed to your build wooo woo

PWR Water-to-Air


Mustang Cobra heat exchanger


then I need to research and find a good pump that won't make too much noise.

here's the basic design of a water to air setup

[celicast3sgte]

fascinating. wayy more in depth 7afte build than anyone else. cool stuff

[x_itchy_b_x]

id use an oem cobra pump also. least thats what ive read alot in the past.

[normality78]

damn... i was just thinking of the pro and cons using watercooled intercooler there you've already planned it. Im impressed....

what is the cam spec you're going to do?

[trdcelica94]

NICE!also good choice on the turbo...

[trdcelica94]

isnt a 255 fuel pump extreme for a 7a? i hear a 180 is enough used in some eclipse's

its not extreme? but once u change i recommend u put premium gasoline

[jcbass7]

steff, can you run the IC anywhere in the engine bay? since all of the heat is getting removed at the exchanger? makes sense, kinda like the st205 IC.

do you know how you plan to route it yet?

yes. the heat exchanger will be mounted in front of the radiator. the piping will go directly from the turbo compressor outlet to the throttle body and the intercooler itself will be mounted right inline with that (about where the stock airbox would be). pretty much just the same idea as the ST205 water to air setup

Here's my Excel Spreadsheet Parts List.
the green are all things I have bought and paid for. the red is all stuff I have yet to buy.
I'm pretty happy how the red has shrunk in the past few months. I'm getting excited about this.

[jcbass7]

nice spreadsheet, i need to start one of those.. actually i need to start like 4 of those... engine, suspension, exterior, interior...

[normality78]

damn... you put me on shame. I cant even do out tat details whn im preparing for my turbokit.

[elvasoshexai]

i had a spreadshhet too but it ended up so disorganized... i thought i was crazy for the amount i spent on my setup.. my cost was similar to urs.. but seems like u got a lot more than me =/ i guess i suck @ bargain hunting

[celicast3sgte]

i know i got that price beat... :-/ hahaha im up there around itchy B!!!

MY BIBLE!!!!!!!!!!!!!!lol

btw, are you going to add a wideband o2 to that list??

[hurley97]

btw, are you going to add a wideband o2 to that list??

its not on the list because I was thinking about whether or not it would be more cost effective to just dyno tune it for $50-60 rather than actually buy a wideband. I was looking into the AEM UEGO Wideband but I have no place I want to mount it.

doing that would be acurate as far as tunning it but you want a wideband to keep an eye on things if something happens
