    2nd Gen RX7 and 93 Nissan 300ZX n/a

    So, my friend with an N/A 2nd Gen RX7 with massive top end and loads of power is about even and/or a little bit faster top end wise than my friend with a N/A 93 300ZX with all the N/A goodies (the ones ricers usually get). So tonight cruizing in 5th my friend in the RX7 goes past me in 2nd (I was going like 35 trying to save gas) and so I downshift to 3rd. Well he goes into 3rd lets off for just a sec then floors it again. By then I am gone, in third I got even with his speed in 2nd (and his like 2 car jump) then passed him fast and pulled 3 cars before going 4th then it wasn't any fun anymore cause I was just pulling. So shut it down on my end at 105.

    Well the funny thing was that the 300zx owner was riding with the RX7 guy so that both totally agreed my car at like 5-6 PSI is faster than their cars. So I am so stoked to get my new injectors and run 10 PSI.

    I am addicted to boost

    Lol @ broken rx7s. One of my friends has a 87 FC (2nd gen) that ran 11s on street tires with NO traction with full interior, etc. with around 400 hp. Now he is making alittle more because of porting the motor and other new toys here and there. So just because you beat a fubared RX7 don't get too ahead of yourself!
    **SOLD** 93 EGT with more suspension mods then your average riced out civic's # of decals + useless "bling/style/culture" mods! **SOLD**
    95 EGT New beater! And gawd damnit shes NOT pink!

            Ya I know. If my fuel was good enough I would be running that. But between the SAFC II, RX7 VAF, and my MSD BTM the car doesn't want to go past 7 PSI. So I am upping the Injectors. and EGT, Lex, and Redfox all of BPT's while I have a Turbo BP. Ya just about the same except for me having a better flowing head, and higher compression.

            But hey, why does that matter.

            And my Friend's 7 is actually pretty quick. It is a solid 15 sec car (which is fast around here). So I know I am at least into 14's at 5-6 psi. I am happy w/ the MX-3 for a DD

              The better flowing head will give you better top end with less torque down below and more turbo lag - not a huge issue with our small turbos.

              The higher compression will result in more power as well as higher EGTs etc .... maybe why you need more fuel.

              I am still wondering as to why you need more than 370cc injectors for 10 psi ... let us know how it turns out.

                  I'm proud that you're keeping the tune safe until you upgrade your fuel system. I'm glad you're not fubaring up your engine by getting greedy

                  [edit]
                  That sucks that a solid 15 second car is quick around there My stock volvo ran a 15.07. Maybe elevation difference, eh?

                    Thats Why Vics is still enabled. And I am tuning to use vics. Also I don't know how a better flowing head would cause turbo lag. I know my friends turbo lag went down after P&P his head. hmm...

                      The restriction in the GTX head causes higher air velocity - which increases torque at low RPM .... which is why I mentioned less turbo lag

                        I thought the more air you could move the quicker your turbo spools. But I could be wrong.

                          Well take a look at VICS ... it's there to decrese intake size at low RPM and make more torque/power at that low RPM

                            ya but more torque doesn't equal more air movement. That is proven with the invention of the Rotary engine.

                              so how do you explain the effectiveness of VICS or similar systems?
