35hta + injectors

[sniperelite]

I am going to get the 35hta and possibly go bigger in the future. I know my friend was running a 37r and he maxed them out at about 630whp. Do you guys think I should be fine sticking with some 1000cc injectors or should I up it to 1150 or 1600cc's just to be safe for the future?

better safe than sorry i guess, if you do get 1600s at least you know you wont max them out and you have more than enough flow.

 

[sniperelite]

there shouldnt be any downsides about using the injectors at like maybe 60% the majority of times is there?

 

[turboglenn]

I hear the 1600's are hit and miss as far as flowing correctly and reliably. Personally, i would say 1150's unless you plan on running E85

Ya I think I am actually going to go with the FIC 1150cc injectors for my setup. Seems like they are real good quality injectors.

I vote FIC 1150's. I'm running them with a small 16g and they idle like stock. No, there shouldn't be any downside to running them at 60% all the time (or anything lower than 85% for that matter). Mine are running at like 40% max right now. After talking with Thomas Dorris from ECM Tuning, he also recommended me to go with the 1150's over the 1600's because the 1600's were hit or miss with getting them to idle right and also with tuning. And I'd rather not take the chance, especially since I have no idea when I'm going to max out the 1150's, let alone need the 1600's.

Ya after doing more investigating I am going to get those FIC 1150's. Do you think I should rewire my 255 or get two 255's working together?

The best way to g owould be dual fuel pumps with duall rails with one rail 1000cc and the other like 450-550cc injectors I was told by the guy who built my engine that anything over 1000cc on a single rail system will have idle issues. FIC 1150 should be fine actually thinking of getting some myself for my Precision SC61 later HTA. or 40R.

Talk about overkill!!!

There are probably only a few running dual rails. Our stock single rail can handle almost anything the average DSMer wants to throw at it. I've also never heard of having idling problems with a single rail system and 1000cc+ injectors. Maybe if you have the wrong engine management this would happen.

People idle the 1150's fine on a single rail. One way to run a dual rail setup is to get the Magnus SMIM with the dual rail option. You then split the injector harness wiring to the second rail and you will thus have 8 injectors running in parallel (versus sequential).

Try the single 255HP or MKIV Supra pump with an upgraded line from the fuel filter (including the filter) to the fuel rail. That's the single biggest restriction on the stock fuel line.

And I'm one of them.

There is a DSM tuners member,who's name is twicks 69. He runs GT4088 with a dual pump setup, 1000cc injectors. He makes more than 700WHP and ran like high 9's. Just find him and ask. He is very nice and knowlegable guy.

1150cc wil be more than enough. I've done plenty of research on this very topic.

I will also confirm this. 1150cc are plenty for you, UNLESS you switch to E85 in the future. If you make the switch then 1600's are the way to go.
