570whp mustang dyno on pump gas?
 

Hey all
So I am running a Ptuning gt3582r turbo kit with the ptuning exhaust muffler deleted and a DTA WG. As I was getting tuned my first pull was 553whp@ 19lbs. I was boost creeping like crazy. While looking at the AFR I noticed once it started to creep my AFR spiked to 14.6 obviously. I did notice that there was 0 knock voltage. Tuner made some adjustments to fatten it up top so we ran again. This time put down 569whp@ 20lbs. Keep in mind this is still 11.0:1 stock internals. Still 0 knock voltage but AFR was down to 14.2. The tuner showed me that my 1000cc injectors were at 85% duty cycle and this is just too much power for my walbro 255. So basically 1 boost needs to get under control, 2 it seems as though these motors can take a bunch of boost on pump gas. Later that week I put the 2.25 disk in to try and get it under control. It suppressed the spike a little longer but it still happened a little later in the rpm band. In conclusion I need a Bosch 044 pump, and some FIC 2150 injectors I think that may solve my fuel starvation issue.
End report 1

22psi will net you 600whp its been done 3 years ago on a stock engine :D A 340 rewired fuel pump id1000 injectors should get you there .

Remember as the boost goes up then your fuel pressure goes up putting a lot of pressure on your pump 18psi on a stock fpr is about 61psi fuel pressure.

The 340 pump gives you 800 hp of fuel at 50 psi fuel pressure ,if your base pressure is 70 psi your loosing 100 hp of fuel Lee.

dam 20 psi on stock internals on pump gas, thats crazy

I was running 18psi with a crappy greddy emu :blink: .

Insane numbers on pump/stock internals.

(PM sent :) )

I have never Hurd of these numbers on a stock block pump gas car on a mustang dyno that would put you over 620on a dyno jet

Who was tuneing the car

Yeah I hear that ^ I stopped at 500-515 I'm going to e85 cause I'm sketched out as it is

Ya I'm going for 750 on e85 2000cc injector twin 340 pumps and -8 fees -6 return but I only want 450 or so on pump on dyno jet for dayly

Good goals !

Which Injectors did you go with FIC/ID ?

Last time I checked it was impossible to run close to this much boost on pump gas on the stock engine. Anyone that runs this much boost and makes that much power must run e85 or race gas.

maybe his pump gas is more than 93? that seems way high for what im used to on pump gas.

The car is being tuned by spec ops Motorsports in Fayetteville NC. I am using FiC 1000's

I'm on Simons they can use any fuel

You mean Siemens ?

No, semens :LOL:

Ya lol sorry

Nice numbers! Update your sig lol

What octane fuel?

The old adage "It's always the quickest before it blows up" certainly applies to this situation. Good thing you caught it on the dyno, can you imagine feeling that on the street!


You guys do realize the car was leaning out and he isn't keeping it like this right? :LOL:

Yes just shocked it was pushed that far is all

Yes we did realize it leaned out but we didn't have any knock or any sign of bad things happening. I think it can take it, just needs more fuel. Maybe fuel is more stable out here I'm not sure. All I know is that the engine wants more fuel

This doesn't make sense to me. How do you go from 467whp @ 15 psi to 569whp @ 20lbs. 100hp with 5psi? That's crazy efficient and on pump gas, but yea fix the boost creep and get the afr to 11.3 then I think it will be back to normal numbers. Do you have a aem fpr did the tuner try raise the fuel pressure?

Because the timing was to safe,when i had a stupid safe tune at 12psi,we put the boost up to 18psi without needing to touch the timing.One degrees on my mates 400whp sc lost him 30 hp.

Ps raising the fuel pressure puts to much pressure on the pump causing it to not do its job Realstreet did a fuel pump test go google it mate :-)

Ya I'm doing a lot of looking into the Bosch 044 and some 2000cc inj. I am still running a stock FPR. Not only was that gain from 5 more psi but also a much better tuner. I kinda want to see what the very limit is for pump gas. But like I said really need to get boost under control first

An inline 044 will go a long way.

Personally though, Id run the in tank walbro 400. Just my personal preference.

I have considered it but I have a roll cage lol. So without having to be said its a pain in the ass enough without the cage, it's even more with. Another thing my redline is 10500 so boost must get under control so I can take it there

Are you on stock lines ?

Shit that Intank isn't looking as good as the 044 haha.

Im doing the exact same in the uk with a gt3076r Taking 3 years to find a good tuner ,by the end of the week the shine arches will be done with the tune.

Facebook Lee Todd s2ooo@hotmail.co.uk :-)

this gives me hope that I will be able to make a reliable 500whp on pump gas now with my P-Tuning 3076 .82 AR kit!

Yes I am still on stock lines. Just remember I am running a 35r not the 30

You sure your knock sensor works? :LOL:

14s are Suppppper lean in boost, idk how it couldn't knock

16 to 18 psi should do it I should know soon.

You guys are crazy

Yes I checked it out because I thought that was strange but it still has ohms and voltage reference

I didn't see an answer for this question, but what octane fuel are you running Ranger?

Shit. I say do whatever you gotta do. If something goes wrong them build the motor :tipwink:

This... Id like my engine to last a while

Sorry I'm running 93

I mean it does kinda say it in the title pump gas so I made an assumption

:LOL: :LOL: :LOL: :LOL: :LOL: Love you guys .

http://img.tapatalk.com/d/13/04/02/zaradyru.jpg New part being tested for ptuning. Report to follow

That's the same test disc that PTuning sent me........I have it installed but I am still getting boost creep.

what is that?

That's PTuning test disc. It's the 2.25" ID boost regular disc (that came with their turbo kit) but with a 1.25" (IIRC) extension to help control boost creep. It gets installed between the down pipe and the intermediate pipe via a V-band connection.

10500 rpm on stock engine??

Dude's either got huge balls, or deep pockets

This guys hat --> :tipwink:

bahahhahahaha fawking LOL

For sure big balls lol. These motors can do amazing things but many are afraid to push the limits. Stock cams are capable of 6k rpm's and with this head design and efficiency along with the bore and stroke being almost square the higher the revs the more power made.

That's insane. Nice numbers. Now to run higher boost safer you would want a new head gasket correct? Like the inline pro gasket?

This is the kinda crap we need! People pushing it to the limit and not doing what EVERYONE else does! I mean just look at it... the guy making 690whp on stock fuel lines with just a walbro 400. Now this guy making 570whp on pump gas! Im really convinced its alot easier for people to make 500-600whp than people think. Im very interested to see what my car makes... P-Tuning GT3076R AP1 Stock 11:1 Motor walbro 255 and ID1000... Was going for 425whp on 93 octane and then another map with 110 octane Cam2 and max out the setup and try to get a 500whp mustang dyno car. But with this coming out Im just going to try for 500 wheel on 93 octane. Hell if it doesnt knock! Fudge it!

You need a 340 rewired pump to get to 500whp mate I was at 80% fuel same setup as you at 460whp 13psi on the fullblown stage 2 gt3076 .

http://www.evans-tuning.com/dynos/20...whp388tq-kpro/

Right here. 533whp on ID1000 and Walbro 255

what fuel are you on? Ethanol/E85 yeah the 255 wont cut it. But on regular petrol 93/100 octane I should be fine. I would honestly like to pick up a double pumper hanger with a second walbro 255 and have the full blown double pumper intake with stock fuel lines, stock fuel rail, and stock fpr! haha

Here's mine from a few summers ago...I got a lot of crap when I posted this up, but maybe opinions have changed.

Full-Race kit w/GT35R, 255 walbro, ID1000's, K-Pro, 91 pump (1 mile above sea level)
IIRC we were running 17.xx psi

Just pump same as your 93 evens says in that link that its limited on fuel and to be honest I would never use meth to pull more timing to get more power ,I would tune the hell out of it then add the meth for safety :-)

Ya my 255 was running out. A bigger pump is needed I truly want to use 2 Bosch 044's but that's down the road when I build my engine. And some 2000cc injectors

perfect! this exactly is what im looking for. Except with my p-tuning kit I should be getting full power and torque a good rpm sooner. I know currently I get full boost at 3800 rpm and pull to 9000. I think if I can make 500-550whp that has near 400tq and a 5000+ rpm power band that would be a very VERY fun street car!

this is with meth, not just pump gas, sorry to be a downer but running 20 psi on a stock motor wont last, good luck

Hey there Debby nobody said it was going to stay there lol. It was simply a post of damn no knock, 20lbs on pump

Was this stock compression?

But hey, you know nothing eh?



That was a direct port WMI kit too lol far from "pumpgas"

Yes, uncracked motor w/~30k miles

Makes me wonder what type of numbers i will be seeing using a 255 and an EFR7670 with ID1000's with a 9:1 compression.

Get a bigger pump and bigger injectors

Was that to me?

Yes

Yes, uncracked motor w/~30k miles

Hotf@#kingdoggy dude. 17+ psi 11:1 comp with only 91 octane, woooooo weee. Those are some nice numbers! How long have you been running it at this level?

I think I may want to convert my gt35 set up to a Borg Warner EFR turbo. I obviously know things that need to be changed like the flange, eliminating the external WG and ic pipe hot side reconfiguring

I wouldn't my tuner said they get stifled topend due to the internal wastgate.

And if you have boost creep already it would be like using a greddy turbo feck that.

Who's your tuner?

Jeff Evans posted in here recently about how blown away he was by the EFR's performance.

Something to the tune of "I've tuned thousands of cars, and at this point I am not impressed by much, but the EFR blew me away"

Thanks for the advice. Looking to keep it somewhat of my DD. Would the 340 be enough? As well, What size injectors?

You can actually get the EFR7670 with a 1.06 that has an External wastegate feature.
