Hello More Experienced People Than Me...

I have a 5.7 build using the Terminator X and a Precision LS 7675 Turbo with the Holley Sniper EFI intake made for EV1 injectors. Turbo is capable of 1100 HP as advertised. Bottom end is all forged using PRC heads.

These are the injectors I was thinking about using: DeatschWerks Fuel Injectors 16MX2012008

Questions
1) Are these enough for what I'm doing? I think they are but I've never built a fuel injected LS turbo car. I'm a big block Ford with a carburetor guy but I'm digging the LS stuff. Easy power... Low buck.

2) Is there a better & cheaper alternative?

3) Other advice?

Thanks in advance for your help!

 

What fuel is the first question? Fuel pumps and setup. That turbo will go about 700 wheel HP on that combo Btw

 

Fuel for the track will be VP racing fuel MS109. Fuel for the street will be 93 octane. All unleaded fuels. I don't plan on running E85 or anything like that. I plan on taking this motor on Hot Rod Drag Week if they ever have it again. This thing is a toy. Not a daily driver. Total power output isn't a concern other than the most I can make with what I have. It is going to be fast enough no matter what it is. Reliability is my biggest concern.

I have a: MagnaFuel ProTuner 750 Series In-Line Fuel Pump

 

I run ID 1300s (on Flex/E85), had Deka 80s (Gas), ID1000s (Flex up to E60) before that. You ought to be in business with that set up. Deatschwerks have a good reputation however I haven't run them. My Dekas were good to go on gas btw at 750-800 on gasoline (twin 340s & 525s on Flex). I ran ID 1000s at the same power level. All of them were tuned well and drove great.

 

Outside of billet atomizers... stay away from aftermarket injectors.

get deka’s, Denso, Bosch, etc.

80s or 120s will be enough. 60s will get there at 4 bar of fuel pressure but you’ll be totally out of injector at 700whp

 

Thanks guys. That helps. A LOT!! I Googled the injectors mentioned and the Deka 80's are about 1/3 the cost of the Deatschwerks and that is huge. I do like the idea of being able to run E-85. I just figured after seeing the price of the Deatschwerks injectors High Impedence that would flow even more fuel for E-85 would be crazy expensive. I'll look at the ID 1300's today.

Do any of you have links to articles that discuss fuel pressure v.s. injector flow? I don't have all of that straight in my head yet. I know higher pressure will result in more fuel going in the cylinder. I just don't know how you figure out what is right for your injector unless the injector info tells you how much fuel pressure to give them or perhaps provide a flow v.s. pressure chart. Thanks again. Very helpful info!

 

I'm a fan of the buy big and buy once when it comes to injectors. You can get Bosch 210's for $544. You don't need anywhere near that much injector, but they likely cost less than the ID1300, so why not?

80's will be too small for decent power down the road on e85 if you go that route. My 80's were done on 12lbs with a mild 5.3. Made 560/600 at that level.(43 base, and voltage was dropping) Now I'm at 70 base with good voltage and pumps. I can squeak out 19lbs and inj. DC is maxed. IF you never plan on E85. Deka 80's are great IMO.

inj press vs flow calc

Hey Thanks! That is awesome info. The Bosch 210's do seem to be the way to go if I will be able to run E85 also. There is a lot of E85 around me so it is easy to get. The pressure v.s. flow calculator was spot on what I needed! I have it bookmarked. Thanks again! I'm sure I'll have more questions in the near future but I'm having a ball learning about this stuff.

 

Now that I've looked closer that Bosch 210 has a EV6 connector. My Terminator X is for EV1. Is there a Bosch EV1 equivalent or does the EV6 fit somehow?

 

Check out snakeaters, ive got 1500 and i love em

 

you can get injector harnesses from Holley with any plug you want.

they do also make little adaptor plugs as well.

the other option is snake eaters. China injector. Kinda like the cheap smart fire injectors, but a little better reputation.

but like stated.. 80s will go a pretty long ways on 4 bar of base fuel pressure.

Heck I ran 21psi with 60s on 110 this year.

if you buy Bosch 210s... make sure you get authentic Bosch 210s.. and not China clones. Lot of that going around

 

80s will go a long ways on e85 as well. i ran 9.01 at 150 mph on e85 with mine 3510 lbs street car 58 psi fuel base. . 18 psi boost 6.0 with s480 turbo. ..

 

I bought the flow matched Bosch 210's with EV1 connector from Turbo4Less.com. It seemed to be a hell of a price for what they can do comparted to others out there. Thanks for the recommendation!
