I am building an h22. I know waht all i need but not sure what cc injector to go with. i think 1000cc would be good but im not sure. i am gonna be running and 800hp and i want injector to be able to hang. what should i go with? also as for brand names i was goin with dynamic injectors? any insight would be awsome

TravisBiggie

800 WHP....1600cc outta do it, 2000cc minimum if you are using e85


google next time

1000's won't get you there, 1600's on race gas or 2000's on E85.

Tell us more about this 800 HP set up, what turbo, fuel pump set up and ignition are you using?

These types of threads are my favorite. 800hp, yet the can't do the basic fuel calculations to figure out fuel consumption... I have posted these exact formulas years ago repeatedly.

pssssst some of yall need to research a little more 1000's can make the power i mean **** if thye made this power on a single the h22 should do it


JFK78′s SOHC D16 Monster

Current best performances:
9.49 @157.3mph
This is the car that pioneered the ever popular vitara piston builds. It has held and broken all power, trapspeed, and E.T records for a vitara piston’d D16 for many years now, and continually pushes the boundaries for a street class turbo D16. In 2010 it shattered many records again, becoming the worlds first street class D16 to break into the 9′s and quickest/fastest/most powerful vitara piston’d D16 with a blistering 9.65 @ 153.8mph blast down the strip at well over 40+psi of boost!
With the continued gracious support of several sponsors (Golden Eagle, Bisimoto Engineering, Arias Pistons, and Competition Clutch), we have finally stepped it up this year beyond the stock sleeved/vitara builds of the past.
Stay tuned for further progress/results on the 2011 build as we push farther into the low 9 second range. The new build is a 76mm o-ringed G.E. Sleeved block with custom Arias pistons, Bisimoto 3.6 camshaft, and SpeedFactory D2B transmission conversion.
We are going to campaign this car in the BOTI Street-Comp and IFO FWD classes this year, and are shooting for low 9′s at 160+mph.
2011 build specs:
794whp/479tq @ 39psi
This is the new D16 hp record!
Engine:
G.E. sleeved D16Z6 block
Custom 76mm Arias pistons
Eagle rods
Injector Dynamics 1000cc injectors
Dual Bosch 044 pumps

Ok so it's possible with 1000's, I bet they are maxed out at +100% duty cycle at 800 whp.

A safer bet would be atleast 1200's or bigger.

Way to get a little shameless promo into a thread that only needed a simple answer.

The quick way i've always thought about it is 6cc per whp...its not exact, but it works well enough

1000cc x 4 injectors = 4000cc total
4000cc / 6cc(per whp) = 667

Granted thats a really rough estimate, but serves to give you a quick idea of what you're working with. For E85, add 30%...meaning instead of using 6cc per whp, use roughly 7.5-7.8. Again, this is by no means an exact science. Fuel pressure and other factors influence what it will truly make

sanman000719

i showed real life results based off someone elses hard work not a forumula, not a guess but a reality.

the car did great numbers all around on the smallest motor out there.

1000's cranked up produce around 1299cc's.

realiability i used rc1000's for 3 years at 80psi for a base, and at wot was at 100% duty thos are now in a car in las vegas and still going

OneBadTurboCRV

This Guy makes me laugh... you are trying to compare fuel consumption on two completely different engines/setups. This coupled with the fact that what you posted looks to be a "race only" setup - cage, window net, seat, ect... What works for one specific setup won't work for every setup. This is the pproblem with kids on this site; too much speculation. That's great if you can't afford to purchase a good fuel setup, but why take the chance in the first place? That engine is obviously tuned on the very edge of failure. Whatever works for you I guess...

OneBadTurboCRV

Here it is... For those who are illiterate, it says HP and not WHP.

sanman000719

yah my bad what was i thinking i must have missed the memo that put the single came far ahead of the bigger dohc motors when it came to fuel consumption and making power.

and hp must be the new higher standard over whp man things have changed.

guess i really didnt make 650/408 on rc 1000's and e85 either because the math says no way ooops my bad it could be possible since it was only whp. no way it would have made that much hp

please continue to educate.


but please continue to educate me

So then your condoning running injectors at 100% duty cycle and double the fuel pressure they should be at??

Why in the hell would anyone spend the money to build an 800 hp car, and risk blowing the motor up because they ran out of injector? It makes no sence, 800 hp needs more than 1000cc injectors, period.

Schister66

^^I totally agree

sanman000719

this is to funny so you think the injectors are at 100% duty everytome the key is turned and the car is running??????

also that the fuel pressure is maxed out as well?????

hmmm crazy. i ran a street car like this for 3 years the injectors are still going strong to this day. I pulled them out for some id2000's because i fallowed the crowd thats the only reason.

so yes with a good tuner i do.

sanman000719

this is another example of the 1000cc injectors


x2 been on id 1ks on q16 for about 3 season! switching to id 2ks soon!
ID injectors ftw!

We get it...those injectors worked great and have yet to fail. To me, that has nothing to do with the tuner, it has a lot to do with putting all your faith into the quality of your injectors. If they fail, the entire setup fails. Personally, i'd shell out the few hundred bucks for a little peace of mind. Glad to see they're tried and true, but i'm never going to try it

Sanman....
I totally agree that if your running high fuel pressure and the 100% duty cycle you could squeeze a lot of power out of 1000cc injectors.

What I don't agree with is that its ok to do this. Just because your injectors and a few others didnt fail in this high stress situation does not mean that all injectors will follow suit.

You can show me as many builds as you want that have a similar situation and I will say the same thing any competant tuner will tell you, you are asking for disaster.

sanman000719

and there is no garauntee that they wont fail at 43psi base either its a crap shoot

your opinion is just like mine we all have them, and all i was doing is showing the OP that yes it can be done or extremely close to it anyways when others said no it cant be done.

alot of people put there opinions into things and talk alot of others out of it based on what they have heard and never tried. in the end its really up to the OP to decide what he wants to do

93supercoupe

the likely hood of those injectors to fail at 80PSI is MUCH MUCH greater than at 40psi.

If ur gonna get a 1000, get a ID or FIC.

I don't mean to wage an internet war here, but sanman you are wrong, nobody should push injectors to high pressures and run them at high duty cycle just "because it can be done".

I see that in your Sig it says your T1 tuned, let's get tony in here and ask him what he thinks about using 1000 cc injectors at the edge of failure on an 800 HP motor, I bet he doesn't agree with you.

OP. Be smart, don't risk your investment, get bigger injectors.

sanman000719

you must be drunk or high because im not t1 tuned man nor does my sig say anything like that

i said it before ill say it again you dont run around town at 100% duty or at 80psi

tuning at wot means thats where you will achieve those measurements when needed by the ems.

rs250nut

Because you cant use id's safely with mtbe based fuels what are peoples thoughts on using bosch 1600cc injectors for this sort of hp?

sanman000719

1600's are proven to do this as well man many people have done it.

some seemt o forget that before id/fic big power was being made then also

is it safer with the bigger $900 injecotrs well sure it is, but it can still be done cheaper

rs250nut

A lot of people will say you are cheaping out not buying a set of id2000's, all said and done they are bad *** injectors but they cost a fair amount of coin and unless you own a shop etc you may not have the coin to go and bone $900 on a set of injectors.

Look at your post about 3/4 the way down the page that you wrote "this is another example of 1000cc injectors"

It clearly says T1 TUNED on it............
