60's+BAP+255+larger line will take you to about 750 rwhp. with a return style setup.

I am running 95's, two 420L's, dual insulated braided lines, larger rails, Regulatory on the rail and AEM injector driver computer and two stage meth.setup.

3,100 lbs. total. with the largest FMIC that fits.
I even cut down from 255 to 212 and cannot get much leaner.

I know several guys running over 20 psi.. with no head problems.
They know how to keep them on..

Yes, a 1.3 60, with a ten inch tire, at 3,300 pounds is excellent.
KP has been obviously doing this for a while.

This is a generalization and really only seems to fit blower cars...

I was told that the setup you mentioned would take me to 700RWHP... I had all of that plus a FMFPR that was boost referenced... I ran out of fuel at 548RWHP @4900RPMS with my setup.

550 (uncorrected TH400) is about all i got out of a single 255 and a BAP and front mount regulator in my car with the stock lines.

Friend of mine's M6 C5 made 680rwhp (uncorrected) with a procharger on a single racetronix pump witn no BAP and that was all it had it lol.

C5s have a better fuel line setup I imagine, guys seem to get more power out of them then single 255 F-bodies. Also have to watch when people quote rwhp numbers, if they are corrected up the motor really isnt making that power on those fuel system parts.

+1. At 550 rwhp, my fuel pressure was falling off with a single 255, stock lines, return-style (LT1).

My car is an M6 though, and I had better lines.... New feed and used the stock line for the return. I had a verified working BAP, the racetronix harness/hotwire kit, FMFPR, Nasty Nate's rails, etc...

Some pumps seem to do better then others, but I tuned the C5 that did nearly 700rwhp with the single pump and no BAP and tuned my own car as well. I have no explanation why the C5 was able to do that much better (probably +60rwhp or so for the M6) so I asume they have better lines. You have to watch comparing corrected dyno numbers, if it was a cool day/low alt they will be corrected down but the engine is actually making more power, if they were corrected up then the engine wasnt really making that power.

Looking back through the dyno files mine was actually 525rwhp through the single 255/BAP when it started running out of fuel. The same injectors with dual 255s were good for 670-680 and probably more if I had bigger injectors.

He'd better chop off over 1 second and add 20+ mph to compete with the fastest front-mount.

Mike there is no doubt you know your stuff and I wouldnt even attempt to argue with ya on this subject but even though its not the fastest turbo car out there it sure is fast as hell . I just thought the way people talk down about rear mount setups that a 7 sec car would be far off into the future. I guess they are good into the 7`s maby just not the 6`s

My point was that no one ever said a rear mount wouldn't work (correct me if I'm wrong here) - just that it wouldn't work as good as a front-mount.

i'd be happy to have my car in high 9's/low 10's and here is a vette doing 7's..... ok ok, front mounts are doing 6's...... thats awesome. but people have to admit, they were doubting rear-mounts when they came out. now they're in the 7's.....

I think Major Spray's car works pretty good, he's the 2nd fastest stock bodied LSx car and he's doing it on drag radials.

FYI, people that were following STS stuff, this car put down 740rwhp and 800rwtq, 13psi on a built high-ish compression 429ci motor. Power drops off after 5krpms, if I recall correctly, and there are no plans to turn the power up further, as the motor may not like it.

I agree that a front-mount will always be more efficient , but the rear-mounts do get the job done , my car proved that last year when it went low 9's , and Major Sprays hardcore race set up speaks for itself .

More accurately this particular car put down 758/829 at 5,750 rpm at 13 psi., slipped the clutch on the dyno and a complete billet dual disc is going in shortly as a replacement within days. This number was without the heat wrap (which is on the car now and there is a noticeable difference yet to be measured) and this was also without ball bearing turbos (soon to be adjusted). An increase in the dial, will not be necessary as this car is a six speed. The motor is perfect order and the compression is 10.1 to 1. I am sure my future 2,900 lb. 2008 F/I Factory vette and other future builds will garner chit chat as well.

Lets try an keep it apples to apples... the fastest drag radial car has gone what, 7.40@197? He needs to chop about 3/10th's of a second off and 12mph. There where a few people in this thread that said no car would go down into the 8's with a rear mount, let alone in the 7's.

It's still not apples to apples, this thread is about an STS build, not a one-off custom like the Major's...

No its not STS, but he was just stating the fact that just because its "Rear Mount" Does not mean its necessarily less efficient, has to do with the Overall setup. By the way according to the "Top 50 Ranking List" Major Spray is the Fastest LSX, All on a rear-mount. Damn Impressive.

People where stating that a rear mount will not go into the 8's or 7's. That is apples to apples, single rear mount to single front mount, drag radial to drag radial. I think it's pretty clear that an off the shelf STS kit wont be going that fast.
