Sorry for the jack.
I am on 600cc, utec with duel pumps and return with IDC high nineties(around 530whp).
How high do recon i can bump fuel pressure, currently 44psi and not run into any issue?
This just temp, till i get 750cc.

 

prolly 70-80 psi as thats how high my fuel pressure was before I did the regulator mod on my old setup. Car ran just fine

I wouldnt even mess with 750s, i'd go straight to 1000cc's. 1000cc are the perfect size for 500-650 whp setups

 

wow, i'm amazed at these reports on 600cc injectors with such high duty cycles. How are people making power on 440cc?

I've got 750cc's ready to drop in for my 400whp goal (until I do a build), and thought that was too much. I'm glad I found this thread.

 

And I'm upping my 1000's cause they aren't big enough lol

ok ok its for E85

tom

 

thanks everyone for the help! Hal@IP hooked me up. thanks man !

 

will be going with 1000cc for my build.

 

Nice,

Pretty much, if your ECU can handle it, you can never have too big of a fuel system.

tom

 

I'm sure Haltec will handle that.

 

Oh yea 1000's are nothing.......now you can get 2300cc inj....now those may be a little harder to control lol

tom

 

Yea 2300cc inj and twin GT4202 and taking it to RA to tune it

 

I don't think utec can handle 1000cc's.

 

Previous owner of my injectors made 621 hp @ 16psi on meth with 750cc

The car was turboed for 10k miles on the same kit, so it was stable too

 

this with utec?

 

not from what ive seen.

the injector dynamic 2200 throw right into a stock 2.0L 4 banger idle and ran just fine. video on youtube.

with accurate latencies you can tune those right in

They are pricy but anything over 1000cc is. Hal is looking at 2200s for his race car.

 

st8dum1 and Thom,

What 1000cc injectors are you all running? I have 1600cc off the drag that are for sale (and no I am not going smaller, not switching to E85, not methanol, etc.)

 

No.

But I'm going to be running Utech Just until I do my build in 12 months.

edit > I settled on it for the time being after reading a few people saying they had no problems with idle or driveability on 750cc. That was my only concern, since I'm not going for big power.

 

I think they are RC's but not positive. I'll have to ask Larry @ SP. lemme know what you want for the 1600's, and what they are.

Thanks,
tom

 

Is a utech like a bootleg Utec? kinda like Soney lol...

 

Don't be hatin on Samsmug now!
