Want some feedback on some tech info.

[AZ3.8Camaro]

I am making a webpage that will follow the entire buildup of my car. It will have tech info from suspension components to the turbo.
Only some the turbo part of it works, but it has a lot of good info. Have a look.
Click tech info, then one of the turbo links.

Any suggestions?

Again it will ALL work soon, but for now, I have compressor map stuff done because I just went through it. I will put cam info on it, as well.

"so it would fall AS FAR out of the surge line, but it still would." ehh what [img]tongue.gif[/img]

it should be noted that the Garett T-70 and the Master Power T-70 (super 70 trim) have WAY different maps....... i have been turned down buy MAster power for there map :(
also correct me if i'm wrong but i thought these map where affected by the exuast side too?

also i can't spool 15psi at 3000 RPM with built motor, run 20psi and 4000, 5000, 6000 and 6300 RPM and see what you get it gets much better

cam slection also has alot to do with the turbo you pick....... if your not staying stock

aslo VE CAN be over 100% in FI motor..... only bad part is we have know way to tell what out motor is doing :(

Your original VE cannot exceed 100% for the most part. With a power adder, it can, but thats where the density ratio comes into play. The VE you type in should only be 80% or LOWER for a pushrod engine.

Cam selection has less to do with it that a lot of people think. Yes it has some to do with it, but all it might do is change your VE at some point on the map. For a Heads/cam v6, you might put in a 75% VE and plot some lower points, then put in 90% for the top end points. MAYBE.

The turbine selection does not alter the compressor map. It will change your spool/peak power around, but mostly because of lessened back pressure at higher rpm.

Running 20psi does not get any better, the saving grace, is what I was trying to say in the line your quoted, but I left out the word "not"
Because on a big turbo, it doesn't spool as fast, you might not fall over the surge line like it shows, that spool up line would likely slope to the left considerably more. But ideally a little bit larger engine would work best.

i think what i'm trying to say is. dont just pick a turbo based on 3000 RPM..... plot all your point to see where its going to be over the hole RPM range [img]smile.gif[/img]

For me i want max power, so on the edge is fine at low rpm but after spool in the high RPM i want that perfect in hte middle on the high side of the eff% for the turbo...

when i was running my 6 psi spring i admit, this turbo hardly made any noise.... at 11 psi it seems to like it alot better and at 15 the even better....

also give some numbers and step bye step that math out one time..... so noobs can do it...

still great write up.... thanks for clearing a few things up for me [img]smile.gif[/img]

It does cut across the middle on 20 psi. But it will stick out the surge line if it were to spool up quickly.
For your car, which is a special case of not being on stock internals, the t-70 is not a bad choice at all, for a track car.

The 60-1 and 62-1 are also great matches that would spool a little faster I think, for a more street driven car. They also work better at lower boost levels.

anyway to get a t70 to spool sooner

Nitrous or a 2 step I suppose.

My Favorites- Updated ! Great stuff man :cool:

Now do it for 60-1 and 62-1. I have a good feeling those are the best.
