Best place to get 800 to 1000 cc injectors

[diesel des]

So I'm looking for at least 800 cc injectors. I have heard Siemens delkas of that size struggle with idle. The 630cc Siemens in my urs4 are fine but to feed a billet gt35r in my URQ I need bigger. Are Bosch ev14 the best option? What about ansu injectors. Seem expensive. Where is the best place to buy. What size, and spray pattern are stock injectors. Cheers des.

I use siemens deka 835cc last year and make 650hp, best injectors ever had,very good on idle and they very good price plus direct fit.

Ok that's good to know. What fuel pressure were you running at at what duty cycle were they at 650 bhp? What are you running now?

Hi des some ev14 1000cc injectors would give you more head room since your mapping it it wouldn't matter,I have grams 1000cc injectors they look very similar to injector dynamics.

I use 4bar presure with an8 fuel lines 2 pumps using them almost to max 100%, but was no problems one year running.Now use very old stile bosch 1600cc using them about 58% but on petrol they not good idle at all plius they low independence so need to use resistors.Is very hard to get big injectors work on idle.My target 1000hp so this i need very big.New car we build we will use again that siemens deka 835cc.I run them 3 years and no clean nothing they work perfect.

So with the 835cc Siemens at 4 bar they were almost maxed out at 650 bhp on pump petrol? That would make me nervous a bit.

Hi des from Danny at Dna very friendly and helpful

EV14s are regarded to be the best bet. IIRC PRJ said even with up to 1200ccs on our engines they can be tuned to idle perfectly.

Yes if your target about 700hp go for 1000cc minimum.

I agree also, siemens 875cc will be just about flat out at 650hp.

I'd get some 1200cc injectors, then you have head room in the future.

Ok looks like 1000 cc should be my target. I don't plan on much more than 600 bhp but... Do Siemens do 1000 cc injectors.

Also when does a stick fuel rail top out power wise? Seems nuts to be talking about using a gallon of fuel per minute.
