Well I'm finally breaking down and spending some money on the car so I thought I'd go from my old LS6 intake to the LSXr and see what improvements I can get from it.
Anyone else have experiance with the swap on a FI car?

Ok this isn't very scientific but from seeing other dyno sheets out there they seem to be getting about a 9% increase in RWHP from this swap in a FI setup. Meaning that if I got 908RWHP at 23PSI through my LS6 intake I should get 989.72 RWHP at the same PSI. Less resistance and therefore more flow at the same pressure levels.
I'm oversimplifying it but it'll be interesting to see what it dynoes after the swap.

buddy of mine does alot of tuning, said to me that on a 400-600 hp car, the lsxr102 is not really worth the $900 for the gains seen. But if your above that or every h.p. counts to you than yes its worth it.
I sold mine cuz I'm a m6 400+ci so not to worried about the low end torque loss and 50-60hp aint gonna bother me, I'll just turn up the boost 1-2psi
p.s. he's tuned probly 100+ cars w/lsxr102, and yet to see one crack from boost and 90% of them running 18-24psi

if he's launching high R's and on boost then ok. as far as I know, most boosted cars suffer lack of torque due to low compression.

I have never seen a dyno sheet for a FAST intake in which it didn't make more power everywhere than the LS6. It's a long runner with better flow characteristics. It's not like switching to a short runner carb style or sheetmetal intake that moves the power band up.
Up until very recently, I have been limited to 3500 launch RPM due to a problem with the transbrake on my old Th350. I still cut very consistent bottom 1.3's with the occasional 1.28-1.29 60' on a really shallow stage. I run the old FAST90 intake.

my original point was.... is the 40-60hp worth $900 for the intake, when you can just add another pound of boost for it.
Also I'm new to FI...... so excuse the stupidity of concern for loss of low end torque.
I also won't have the slips you guys have cuz im leavin .75+second on the table

Really it will only cost u ab $700 cuz shdnt the ls6 sell for $200-250? So, 60 more hp for $700 at ur power level sounds like a good deal. And, if u put it on and then add 1 lb, now uve added 120 more efficiently...

My problem is when you go beyond a certain point in boost you run into potential problems such as spring pressures higher temps in your intake charge also.
For long term reliability I'd like to stop at 25 psi and run solid 8.70. Or just a bit faster. But I could just add another two pounds also.
