TURBODAWG - How much boost were you running?

 

I was running about 65% duty cycle on the Profec B Spec 2. That would spike up to ~23 psi and drop down to ~ 21.5 psi on the top end. I think the stock turbo maybe close to running out of air, especially since it is having to blow thru the stock intercooler and all stock intercooler piping.

Sorry to bring this thread from the dead, but what intake were you running at the time?

 

I was running the HKS super mega flow intake. This is the $105 intake, it is just the filter, and an adapter. It does not come with the hard pipe from the MAF to the turbo, like the Racing suction kit does.

Have you ever dyno'd your car...cause 118+ through the traps is very fast

 

I haven't dynoed the car yet. I would like to know how much power it would make on a dynojet. I may be able to get to one in the next couple of months. I have added a FMIC and switched from the B&B catback to a Greddy Titanium catback. I hope that I would have picked up a little power with those 2 new mods. I haven't been back to the track since those 2 additional mods. My car was at full weight minus the spare tire during that run.

How much boost were you running and what was your airfuel ratio? Also what kind of boost controller were you using?

 

From the buttdyno, did the switch from the B&B to the GReddy feel better? Felt like a lose of torque?

 

Have you gone to the track recently? Have you been able to come close to the 118mph in the hotter weather?

 

LMAO...

 

I was running 23 psi peak, with a sustained boost of around 21 psi. I was using and still am using a Greddy Profec B spec 2. I didn't have a wideband hooked up at the time, I was tuning with Pocketlogger. I kept leaning it out on the 110 octane fuel until I got .88 to .90 on the O2 voltage. I also monitored the timing to make sure that I wasn't knocking. The timing stayed good. I now have a wideband, and would estimate that I was running ~12.5 to 12.2 air fuel ratio.

I couldn't really give you a good answer to this. I switched to the Greddy Titanium and hooked it up with the stock downpipe and stock cat. I had a problem hooking the new exhaust up to the UR testpipe and Helix DP that I had. I sold the DP and UR testpipe and got a new SP/Helix downpipe and a RT high flow cat. The new SP/Helix Downpipe and RT cat fit well with the Greddy exhaust. So I can't give you a direct swap comparison. I don't see why you would lose anything at all when going from the B&B to the Greddy Ti, except for about 20 lbs.

Nice time for those mods. Good to see low times with 264's!

 

I haven't been to the track since the early spring. I hope to get back to the track soon. The car feels a good bit faster and smoother since I installed the Greddy FMIC and the Greddy Ti exhaust, even with the RT cat in place instead of the UR test pipe. I think 118 mph runs shouldn't be a problem even in the heat, unless it is 90+ degrees. The other runs were made with the stock FMIC and cool weather. I think with the Greddy FMIC and slightly warmer weather, I shouldn't be too far under power compared to the cooler nights back in March.

Thanks. The 264's are the perfect combination for a stock turbo, stock ecu car. IMO.
