Anyone else has the portfueler?

[jimmy169]

Hey guys,

Before I ask, some info on my car. Basically I have the Star Stage II turbokit and am now having the engine rebuild with the howell performance bottom end kit with 8.6 compression JE pistons and Eagle Rods. Now with this I bought the portfueler because the e-manage I bought before the shop couldn't get to work (long story, don't ask). I will use 415cc as the secondary injectors and...what else am I forgetting...I also have a stage 3 clutch from titan motorsports. Thats pretty much it for mods off the top of my head, mostly just bolt on parts made for this car because I'm very ignorant and if it's not bolt on I won't know how to get it to work right :-/

What I am wondering, and have been doing searching is what is a safe boost level and how much whp do you think it will give me. From my research, it seems after 15psi things can go wrong with timing and anything can happen, I'm very worried because I can't afford to rebuilt the engine again. I was very excited at first thinking I could boost 20psi but then I read some horror stories. It seems the 18-20psi range is a dangerous one on pump gas so I'm thinking 15-16psi will be safe but does anyone else here have the portfueler, if so what boost are u guys using daily?

After I break in the engine I will have it dyno tuned but right now I'm just trying to figure out what a safe psi would be for daily driving, not that I'll always hit full boost but I'd like to have as much power as I can on tap

Any help would be appreciated I've been pulled into the money pits with this car and now that I really can't afford to mess up again, I wanna get the most out of what I have sunk into it.

hey jimmy, im doing the same mods you are with the same amount of work. The guy that is rebuilding my engine said that the portfueler kit was a little overkill unless its a serious striclty drag car. He said all i would need was the Walbro 255 pump and the stock injectors should be ok. i might change mine out later for bigger ones but he said it wasnt neccessary.

He also said about 15lbs of boost was safe. He said anything over that might due some damage it just depends on how you drive the car and how well it was rebuilt i guess. Im changing out the cam gears and putting in an Unorthadox underdrive pulley. So hopefully that will adjust my timing enough that it will run great at higher boost.

I guess it just depends on what your building the car for. As for me spending $1100.00 on a portfueler when bigger injectors and a bigger fuel pump will work just as good and is alot cheaper sounds better to me.

 

[siueclipse]

you know what.. rather than ask us if your car will blow up, why dont you get a wideband and find out for yourself how much boost you can run..

jeeeezzzzzzz

 

[420a16g]

no need to be a jackass. you cant get info if you dont ask questions

 

[2fast420a]

no need to be a jackass. you cant get info if you dont ask questions

That's what he does. He is a joke over on 2GNT so he takes out his agression here on the newbies.

As for the question at hand. Don't run more than 10psi on that built motor until you get it on the dyno. Sure it sucks but it will be worth the wait. They can tell you what is a safe level of boost to run after baselining it on the dyno. Fear not, you'll have your power soon enough

 

[jimmy169]

Yeah when I am breaking it in I will hardly boost at all, but as soon as it's broken in, I'd say after about 500 miles, thats when I wil bring it to the dyno.

 

[420a16g]

yea i kinda figured that 2fast... you can always recognize a douche bag when you hear one.

Hye jimmy are you port and polishing, boring your block, etc....
just wondering what all you were doing to your engine.

i was gonna bore my .20 to make sure the pistons will fit nice and snug and to get some better compression

 

[jimmy169]

The engine is at the machine shop now being machined for the 8.6 compression, i'm actually pretty ignorant with this whole thing so I'm not sure what they will do to get it to fit. Otherwise nothing to the head, no port and polish or anything.

I find myself very low on funds now and thats why I'm pretty worried about what to boost. Also I forgot to mention I do have an exhuast system but it's pretty ghetto, . It's a 3" catback to a 2.5" muffler, I'll never go to mineke again, they did a horrible job and basically crimped the end to make it fit to the 2.5" muffler so I'm sure the backpressure is no good at all there but atleast it's not stock I guess.

 

[420a16g]

Damn that sucks that they messed up your exhaust like that. im just running 2.5" all the way back, the guy building my engine said it wouldnt really matter if it was a 3" or not, and i trust cuase he has built 6 DSM's already and the last one was a 2gnt with a 2g block and 1g head. it was pretty bad ass.

as for the port and polish im just doing it to get better flow and i figure might as well get it done while the block is out of the car. I should be ordering my Howell bottom end kit this weekend. then i just got about 6 or 7 more parts and then off to the shop she goes.

let me ask you this. have you heard much about the dual chamber BOVs. I heard they are better then just regular BOVs, but i dont know.

 

[jimmy169]

I decided to stick with the BOV the star kit came with, the hks one because Dino from 2gnt said he ran 19psi with it just fine so it should get the job done. Like I said I just can't afford to switch up BOV's or anything else anymore besides a good dynotune hopefully. I haven't heard about those at all, not sure what kind of dif. a BOV can make for performance thats an interesting question, if I were in the market for one it would be for sound, , thats the only thing I have to give for the little bit of ricer in me.

Hey,

Im not being a jackass. Im sick and tired of seeing these lame ass topics where the person should have better common sense to begin with. Sure go ahead, run just 10lbs, you have a good chance that youll be fine. However, you still have no ####ing idea how the car is running and if there are any problems. Just because you have a built motor doesn't mean shit about the fuel system and if its working correctly. You say that you are worried about your motor and can't afford to rebuild it, but you wont protect your investment. Why risk it when there are devices out there that will tell you how you are running? If you want to play this game then get the equipment you need to protect your investment.

Lastly, don't ask such stupid questions that nobody can really answer with any fact. 2fast has nothing but an opinion but still can't give you a real answer, nobody can.

BTW.. I run 21lbs of boost daily on pump gas with the portfueler. Its clearly obvious that you dont know what you are doing, so please invest in a wideband unit.

Our cars have no problems with timing. Once you cross the 20lbs of boost line, its best to have race gas.

You need to free up your exhaust. You need a 3" complete exhaust for best performance. And to the last person who responded.. your DSM builder friend is an idiot.

Still doesn't give you a right to rip on him. Should I link him to some of the dumb ass questions you've asked on 2GNT. I'm not trying to bust your balls here siu but you rip on this guy like you were never new. All a person has to do is look at some of your posts on 2GNT and see your not the big know-it-all that you act like.

For example: Your last dumb question which was just the other day was asking if you would look stupid running wider wheels in the back of your FWD.

yea siu i might be new to this forum but im not new to DSMs. I understand very well what all is involved in building a n/t car right. and im sure jimmy is planning on taking his car to the dyno, i am when its done and anyone that didnt would be an idiot. as for the portfueler thats great that you 21lbs all day with it, but there are other alternatives, i mean the portfueler is new so dont knock anyone becuase they dont wanna spend $1100 on it if they dont have it. as for adjusting the timing im doing that becuase i want, whether it will help with the turbo or not i dont know, but i guess ill find out when i take it to the DYNO....

as for my "DSM builder friend". building cars is all he does, thats his career.....notice i didnt say job..... he studies this sh!t and knows what he is talking about so if tells me i dont need a portfueler, or a 3" exhaust then im gonna believe him, cuase iv seen what he's built and i trust his work. How many DSMs have you built for people?? im guessing not more then him, so your opinion doesnt mean jack sh!t to me.

I forgot to tell u guys what guages I have I apologize. Your right a wideband would be a great investment and I will probably get this eventually but until then I bought the EGT probe and autometer guage for tuning, and I think they will use a wideband o2 of they're own when they dynotune, not positive though. I know the air/fuel guage I have no is just christmas lights and really doesn't give accurate information.

Thanx for your concern, heh, and I will def. take that wideband o2 sensor into consideration and will start saving for it now prob. It sounds like this is the sure fire way to know if anything is wrong but, is it? Also, when I keep an eye on this, I know my regular air fuel just jumps from lean to rich depending on if I step on the gas, with this...ah nevermind I'll do that research on my own, in any case I'm taking everything you guys say into consideration so please don't hesitate to give your advice, the wideband o2 I've been told by others to get, it's just a little too expensive at this time which is why I'm doing research on the right boost setting since I won't have a wideband o2 to keep an eye on at first.

edit: , why would u run bigger tires in the rear, that was entertaining...

If you have something like the megasquirt to control timing then your better off than the portfueler imo, i mean thats almost a full standalone right there. Bring that to a dyno and your golden, this is from what I've read ofcourse and from what everyone has told me. Ti

 

[420a16g]

i havent heard of the megasquirt. ill look into that,

in any case im considering a 255 walbro pump and 270cc injectors, i heard adding these 2 components will the make car run real good. whats your opinion (anyone)

Your not going to sustain higher hp with four 270cc injectors alone. You'll either need secondaries or larger injectors.

 

[420a16g]

what size do you recomend?? hahn suggested 500ccs cuase thats what they use in the portfueler but i didnt know if that would be overkill or not.

also, a question that is way off this topic. tonight i got my new clutch in but noticed it didnt come with a new throw out bearing. its a centerforce dual friction (iv heard the good and the bad about this clutch so i already know). but my question is can i just use a new OEM style bearing becuase this one is worn out or do i need to get a special one from Centerforce????

I thought timing was the reason why we have difficulty with things like the S-AFC?

 

[dustyb]

the guy building my engine said it wouldnt really matter if it was a 3" or not, and i trust cuase he has built 6 DSM's already and the last one was a 2gnt with a 2g block and 1g head. it was pretty bad ass

2gnt block (420a) w/ a 1gnt head (4g37/4g63)? i want to see this machining work!!

 

[siueclipse]

yeah i know the question about wheels was funny. i knew it was going to be when i posted it. it was purely a looks type of thing that i was after. i knew it was stupid thought.

i run 440cc injectors with stock injectors and its enough fuel for 500whp. 500cc injectors are good as well, but i dont think youll use them to that extent so the extra expense was stupid in my case.

just because your idiot lights go green when you step on the gas doesn't mean you have enough fuel.

i have never needed to use an AFC so i dont have any direct experience with them, however through conversations with other people and HRC, there is no need for timing adjustment.

 

[420a16g]

2gnt block (420a) w/ a 1gnt head (4g37/4g63)? i want to see this machining work!!

'
maybe i got it backwards. it was something like that

 

[420a16g]

i run 440cc injectors with stock injectors and its enough fuel for 500whp. 500cc injectors are good as well, but i dont think youll use them to that extent so the extra expense was stupid in my case. QUOTE]

so do you have to run an extra set of injectors with stock injectors to hold that much hp, or can you just get one set of injectors to handle that. Im still learning about the fuel system and what you really need to do to make it work well....

 

[jimmy169]

The 8 injector setup is pretty unique, u really don't have to run extra injectors, but if you want smooth idle and good gas economy the portfueler should do it. Otherwise get some big injectors and something to tune with to make it work. Get the megasquirt, it's almost a full standalone, the more I read about it the more I like it.

 

[420a16g]

iv been meaning to look into the megasquirt system just havent had a chance yet.

but if i just wanted to go with bigger injectors. what setup would you reccomend (i.e. injector size, pump size, fmu, fuel rail. etc....)
