anyone?
1600cc on single walbro. upgraded fuel lines to -10, and bigger lines.

just wanna make sure before hitting the dyno...

 

If I had to guess i'd say no.. but I'd like to know as well.

why didn't you just hook up an inline also when you did the lines?

 

Nope already tried max out the pump at about 400-450 WHP on the dyno so i switched to the Dual Walbro pumps.

 

lol then there is something seriously wrong with your pump/pumps...... A Walbro should support upper 550+ easily.


I would imagine a single Walbro would struggle to maintain pressure in a -10 line though.

 

made 540 with 1200's, but that is as far as i wanted to take it. why would you chance it? if you are planning on 600+, relying on a single walbro? thats just asking for trouble.

 

524hp pump gas 627 c16 stock sleeves one pump...MASE'D TUNE

add 12v to the pump with a relay and you will be fine

 

be smart buy a bosch 044 and you'll be fine.

 

kazino42 on here made 630whp on 1000cc's and a single walbro, everything else was stock down to the lines/rail/fpr.

 

Vik-Tek's gsr made 630hp on a single walbro, 1000cc injectors and e85 on an sc61 also. not saying that it's the safest thing to do but it's possible.

Made more power than what's shown didn't record final runs.

making that much power on that pump is risky, especially with lines that big. recommend at least a bosch 044 inline with a walbro 255.

 

so it made a dynojets 630whp on E85 with 1000's? I have to say impossible, I wish that was the scenario because I would have an additional 50+ whp.


#1 1000's are pretty close to being tapped with Gasoline at 630whp, factor in +30% for Ethanol its getting a little clowdy

#2 Walbro 255hp is close to if not tapped out with Gasoline at 630whp, ^^^^^^^^^

 

Hmm weird. I maxxed out RC 1200's and 50psi base pressure on a aeromotive A1000 @ 606whp

 

I have seen it done multiple times.

 

yeah... I guess you're right. Jo-tech an extremely reputable company bought a shitty dyno and throws out numbers like on the back of a fortune cookie. there for it made 630hp at 27psi. it was proven multiple times for alot of haters and non believers at their nissan meet they had introducing the 370z.

 

I would believe it completely if Ethanol was not involved........

I could probably hit the dyno too and show you a 630whp pull on E85 with 1000's, but the AFR's would be in the 14/15's and my motor would be melting. Was it a 630whp pull or a 630whp spike?

 

Ok let me clear up things. I own the car, and built the engine. This car is making the power claimed of 629 whp. It's tuned for e85 and No it's not safe. But it is making this power, the a/r's dip into high 12's low 13's but if you know your fuel's then i'm sure i'm not teaching anyone anything new when I say that stoich is much lower than 93 octane. I have made a total of 7 pulls on jotech's dyno on two different days. So No this is no spike. I guess I may have to take my car to another dyno to prove this power with video of a/r's and anything else needed to support the facts.

whats your base Fuel pressure like 65psi?

 

I made 670whp ONCE on VP Import, lol. Owner forgot to re-connect the second pump, 3:00am in the morning, didnt let off when I told him to, etc. Good times, lol. If someone is REALLY making 600+whp on a single Walbro ... Wow

 

Have fun with low 13 AFR's, I know this fuel very well and I would be pinging like all hell at 13.0afr 20+psi of boost, just did it last weekend at the track for the last 100' of my pass.

 

take it to Tony1 and put it on his rollers, he has told me and a few others several times he doesnt even get 530whp out of 1000's and E85 on his dyno.........

I am not busting your ***** man, I been using this fuel for a while, and its limits with x Injectors have been pretty well established, what does the car make with a proper AFR like 11.8 ? Are you sure you were using E85 and not E70?

 

how much power can you make on e85 and 1000cc injectors on a 2.0?

 

530whp

 

damn that not bad at all. is that with a 12v to the pump or factory wiring

 

488whp on a high compression h22. 110 octane, single walbro and 880cc precision injectors. Duty cycle at 75%

 

hello guys i go by bastard dsm on other forums and im the tuner of viks car. i have tuned hondas and dsm's on e85 and i would like to say that on a dsm.......very crappy flowing heads the change from 93 to e85 was only a 10% change. its has been about 10% for most of the cars i have tuned on e85, i have yet to tune a car that needed more than 20%
change for it to run properly. viks car held 11.8-12.3 till 7800rpm or so then went to 13.3-4 a/f's. the car has no dips in the curve and wasnt picking up any knock...at all. many factors come into play with stuff like this and its not impossible for what was done with vik's car. and for t1's dyno, i used to work at intercrew and i have had a car strait from tony's dyno and dyno at intercrews dyno and it made the exact same #'s. i have even had people say that intercrews dyno was wronge also, the 2nd time viks car put out 600+hp passes was at a nissan meet and 6 cars all dynoed their correct #'s and viks got on the dyno and first pass put down 619hp......people were shocked and thought the dyno was off...then next pass car put down the same thing SAE corrected. i have also tuned my personal car, galant vr4 with a 18g and made 445hp on a single wally and 750's, fuel pressure was at 43psi and 28psi of boost and stock 7.8comp motor.i have also tuned another dsm that made 518hp with 850's on a single wally and stock motor with a gt30r at 27psi.
