![]() Do you have another tuner local who can give you a second opinion, someone who specializes in Subarus?Įxactly my thoughts on the injectors. Quick estimation shows that with 1000cc injectors you are likely going to run out of injector shy of 6000RPM if you keep to the 80% duty cycle rule.Īs far as the block question goes it is likely that IAG's number is going to be a peak number that would yield a short lifespan benefit of the doubt, your tuner may be considering a daily driver tune. Injector Dynamics has a very good flow calculator as well that plots the expected performance of their products. if you want that stuff toss me a PM its just been sitting on my shelf. If you go with lines, rails, and fpr I have a set of the older style Perrin rails with the lines all still hooked up and my factory '04 fpr. Real whp reference was a 129mph trap and high 10's. I ended up swapping to id1300's, tuned for e-85 and made 500whp again with IDC in the low to mid 90's. Real whp reference was a 122mph trap speed and some low 11's I agree with Brother EddieJ, questions about the power capacity of the IAG block should be directed towards IAG.įor a few reference points my car made 425whp on pump 92 with ID1000's IDC was in the mid 90% and it was spinning the motor to 8,000rpm (also where it made that power). ![]() ![]() I would highly recommend replacing your FPR with an aftermarket unit. I made 409whp on IAG's dynojet using FIC1000's on 93 octane. ID1300 will support around 485WHP on E85 according to the FIC calculator assuming a base pressure of 43.5 PSI and 90% IDC. Seriously ID1000’s should barely make high 300’s with decent IDC’s according to the calculators. I feel like I’ve just been punched in the gut. I asked my tuner these very same questions and his advice was to leave it on the 1000’s because he would limit the power anyway due to the block and studs. I have my heart set on making 450whp, and know my current ID1000’s are gonna leave me full of regrets in the end. Reason I ask is I’m about a two weeks away from my tuning appointment, I have poured two years and thousands upon thousands into this build. Or will I encounter fueling problems with that big of an injector on stock rails and Assoiciated bits? Part B: Is it ok to run ID1300’s on stock rails, lines, and FPR? I currently have a DW300c (340 lph), and IWire pump harness. NOTE: car will be flex tuned, so peak power numbers will obviously be on E85 IAG rates this block at 625 BHP, but doesn’t specify what stud that’s with. Part A: How much WHP would be considered safe on an IAG stg 2 Tuff using the standard 11mm ARP head studs (2000 series). At the end of the system, a mixture of liquid and gas will appear.So I have I multi layer question for those whom actually know. If a pump forces the liquid through a tube connected to a system consisting of a venturi to increase the liquid speed (the diameter decreases), a short piece of tube with a small hole in it, and last a venturi that decreases speed (so the pipe gets wider again), the gas will be sucked in through the small hole because of changes in pressure.
