What to do next? 75 mph
The season is about to start in couple of months in here and i dont want to waste my time during it ... i wanna be ready from now.
I have Stage II running 75mph.
Sending my ECO for R3 next week, and got my hand on a new Riva Nozzle.
Will also add a Powershot and a Pet-2100 to be shipped with my ECU.
Now, do i remove the Boost Clamp after installing the R3?
Where do i set my FPR for R3? its on 50psi now and i feel it's a little bit rich.
I am also thinking of adding some gauges to fine tune the ski and get the most out of the mods, what are the most important ones? AFR and Boost is enought? or there are some ore useful gauges to add?
At last, do i go for the Twin Prob? or i stick with my 13/24?

Once you add the reflashed ECU, you can forget about you boost clamp: no longer needed as your PSI & limiter will be raised. I think you should try your ski with the 13/24 you have. Another thing, with the E1, maybe you should ask R&D to set your rpm limit for the R3 to 8500 or you should upgrade your internals. Just my .02

thanks lukygomes for the advise, i will do that.
the weather is too hot here in summer, sometimes it reached 122F in July and August. but the average is 90F.
My goal is 85mph for this season with stock internals.

you should at least consider R8 with 725 cc injectors

yes i wanna be the first to do it here ... you know its all baout finding the right combination of AFR, Boost, Temp, RPM and pump ...
have some other tricks in mind but wont try them before the Reflash ...
btw, i've seen the number plate somewhere before (4342)

How much boost were you expecting with the E1? Riva's rating is very conservatively, 17+ lbs is easily achievable. The R8 was designed to be used with the Riva E1, R&D C5 or the Etech race SC wheels.
The stock injectors struggle to provide enough fuel for an E1 wheel. By using larger injectors the service level of the injectors will be much lower and you wlill be able to maintain adequete fuel flow to the motor using a lower fuel pressure.
When you use the OEM injectors you often have to raise fuel pressure to get them to flow enough fuel. Once you start bumbing up fuel pressure with a RRFPR the OEM fuel pump can't keep up with the fuel demands. This means you then should upgrade the fuel pump (but even if you do that the injector service level is still too high) The best solution is to just use larger injectors.
