Hi,
Im hitting the dyno in 2 weeks just want to see what everyones thoughts are on what its going to make.
Car is an 02 Ws6 M6 RSG Viperspec Tranny, Heres the previous combo:
430rwhp/396 rwtq SAE
-Stock bottom end
-11.1 Compression, 243 heads milled .030, CNCd, 2.08/1.57 manley race valves
-TSP 228r .600/.600 112 LSA Cam
-Ported Fast 92/92 intake/NW TB
-1 3/4 QTP headers, texas speed y, Magnaflow CB
-Mosier 12 bolt, 8.8 truetrac
New build:
The same configuration as above but added:
-2 Bar SD Tune
-Seimens 60LB injectors
-D1SC procharger 8 rib w/4.5 twin intercoolers, 4.50" pulley
-Lonnies dual pumps
-Alky control 100% meth injection
So far the car has a "Frost" base tune. After taking it for a couple street runs it maxed out @9.7 psi at 6500rpm. Car feels pretty slow but thats probably because its drowning in fuel with the methanol. Timing is set at 16 degrees.
Im eager to hear some dyno estimates. I will of course post back once the results are in.

no wb at the moment. I actually figured it would only pull 6 to 7 psi with my heads/intake combo but apparently its not as efficient as i thought.
When i say it feels slow it seems like its lacking the throttle response that the NA combo had. I think it will wake up once it gets dynoed on the 8th

100 % Street car with great drivability is my ultimate goal. Id like to try to keep the block and lower end in one piece for awhile anyways. Honestly, id be very happy breaking into 600-650rwhp territory. Id definately be on the E85 if it were offered more in my area (theres only one E85 pump in all of central mass).

that 4.5 pulley is too big . Im running a stock engine and cam , running a 8.65 crank and 3.7 procharger pulley making about 13.5 to 14 lbs at 6500 . I Just think that 4.5 with a 7.65 crank is too small . Do a 3.4 and get a much boost as you can and taper timing off . That way you have more boost down low

Boost seems too high for your combination with a D-1SC and a 4.50 pulley. I'd check it with a second boost gauge. I'd expect 6 to 7 psi with your combination. Bob

I was expecting the same results when i ordered the 4.5" pulley from you. The 9.7 psi is on the high end, its averaging about 8-8.2 psi @6000 rpm. I figured on the intake and heads bringing down the boost a bit but maybe the cam isnt bleeding off much boost and maybe the exhaust isnt all that efficient. I think if i were to put a cut out on it or step up the headers it may bring down the boost. According to hp tuners, the kpa readings off the map on the back of the intake seem to reflect accurate readings and i am using the boost pid map sensor 2 bar - baro, which is getting a true baro reading i think. I guess it wouldnt hurt to get another reading from a different source though.
