He has them side by side in each of 4 thumbnails. Just click on each photo, and enlarge to full screen size ... and you can compare very easily the differences.

Not trying to start a debate but spool begins at 2400rpm as can clearly be seen 2psi at 2400rpm. Phil I and a lot of others have respect for you but you are the one claimed the 1000rpm difference I just think proof would be nice! Again I am not trying to start a debate nor do you need to prove anything but I believe you are wrong on the difference.

What DTE is saying is the graph line is increasing in linear fashion until about 3200 RPM ... when it starts to take on 'exponential' increase characteristics. That equilibrate to about 4-5 lbs of boost pressure.
I sure hope the larger turbos also go into exponential 'spool' mode at only 150-300 RPM higher than the Garretts. I want a true frontmount quickhit of power.

BTW, Don't recall your cubes but late spool isn't something you're gonna need to worry about with front-mounts on a C5. IMO, The harder you push it the more gradual you'll want it to kick in.

Cajundude also would be a real contender .... with his rearmount, big lopey arz cam, and probably some N20 onboard by now to combat that 'mythic' STS turbo lag.

If STS lag were of epic proportions .... surely Earl would be aware of such.
Seriously ... my 350 STS has some mimimal lag. I think even C.D.'s higher cubed car perhaps has a small touch ... for which he has discussed adding some N20 ... although other reasons probably far outweigh this factor. Like getting some tire lift on launch.

Well, lets just say I'm not telling all that I know. Honesty, candor and disseminiation of info is sometimes construed as cheerleading. It leads to people being banned, posts against forum vendors being shut down. Big brother is a mf'er. Oh well, whats the saying about a fool and money?

No ... I think mythic is the correct word. Seems Earl H doubts C.D.'s car has any T. lag

relative comparison
f-body ...incon twin turbo kit...gt2871...vs gt3076 on a 346...about 1000rpm difference in full spool time.....the gt2871s were damn near instantaneous on the 346...slower with the gt3071 turbos. On a 408 the gt3076s are instantaneous. i took the small turbos to 736/756 rwhp/rwtq dynojet on a 346. The gt3076s went to 820/823 not QUITE maxed on the 346. 747/920 at same boost on 408. (this is all thru t-25 exhaust housings) The APS kit is better designed...better intercooler....better exhaust flow...it will make more power. YOu guys are in for a treat....too bad the f-body kit isnt slated until end of the summer
