you still have not mentioned which turbo you have.

kyden

between the two, definitely the 57 trim. 6262 is way overkill for 300whp.

450-500 reliable with a good tuner, 600+ but they dont last long at that power level

Aright, I FINALLY had my car tuned on boost again last weekend, and I'm kinda disappointed...

It made 228 whp and 219 lb/ft (that just from memory, but should be pretty close) @ 18 lbs of my T3/T4 turbo. It's a mustang dyno so it will read a little low, and I don't really car so much about the numbers anyways. But it is choking up at the top of the RPM's and I think I have a couple of ideas on what it could be. I am welcome for some suggestions from yall though.

First is my dump tube and intake adapter (sharp 90 angle). My dump tube runs EXTREMELY close to my intake and charge piping, and the exit of the dump is behind the filter for the intake. So I think there is a good possibility that I'm sucking up exhaust into the intake under boost. Also, this is heat soaking the intake and charge piping. I was getting IAT's of about 150F, but some of that could have been that it was 99F here in TX that day.

Also, I'm not sure of the A/R of my turbine in my turbo. It's an ebay version (I bought it and rebuilt it before I knew any better), so I'm sure that doesn't help.

Here are a couple of things about my setup..

Supertech pistons @ about 9.7:1 C/R
Eagle Rods
525cc injectors
2.5" exhaust and downpipe (no cat, just straight resonator and magnaflow muffler. I know it's not 3", but people are making close to 400 hp on 2.5 so I think I'm good there)
2.5" intercooler piping and ebay intercooler
Stock head and cams
Tune w/ Neptune RTP

Those are some things that I think would be relivant to my issue. Anyways, my first plan of action is to move the dump tube to the other side of the turbo. This is the best/easiest thing to do for cost/etc. After that, I'd look into getting another turbo possibly, but that would come later. Also, I plan to wait until it cools down some to take it back to the dyno to get the numbers.

I know this thread is useless without pics, so I will work on that tonight (including dyno sheet). Any advice is much appreciated. Also, should I start a separate thread for this??

BigMike0147

Also, I know the tuner is good because he is well known and has done over a hundred LS's. So I'm not really considering that to be a variable. And he spent about 2.5 hours trying to break that power level and couldn't squeeze more out.

Those numbers don't look right at all, I've seen people make more than that on stock numbers. I'm sure once turbols chimes in he can point you in the right direction..

turbo inside just a guess but maybe the turbo man.. if its a ebay turbo then are kinda wack.... try to put a better turbo on it man..maybe it will help..

Anyone have a good recommendation for a fuel pump for an e85 setup?

Was thinking aeromotive 340. The walbro 255 started leaning out at 19psi. Shooting for 450.

no videos... Ill have to see if some of my friends will record for me.

BigMike0147

Thanks for the reply! I think the turbo is a possibilty (even though) it's a smaller chance IMO. People make good power with ebay turbos all day long so I don't see why mine would be out of breath at 230 hp. I'm running a UGR manifold which is basically the same as a blox cast type, so I'm thinking that's OK as well.

I'm just lost outside of the heat and possible exhaust contamination issue. If I could just change the dump tube and increase the hp considerably, that would be a great find.

And I forgot to add in the other post too that I have a Xenocron 255 lph fuel pump too, so fueling shouldn't be the issue either. Keep the advice coming tho!

Id say the turbo imo, hard to tell without seeing your manifold and chargepipeing... my first boosted motor we went from an ebay 50 trim t3/t4 to a sc34, same boost level dropped over a full second off my et

I think ur turbo setup is hurting you. the two reasons is that one your dumptube is right in front of the turbo, trust me you make great power with just a change like that and the second is that you dont know the ar of the turbo, take some pics of the turbo. Also you try a 3 inch down pipe and exhaust, it will make a huge difference alright good luck with ur setup. Just in case do a compression test on ur motor. Please post a dyno graph alright good luck

DA is best

Heres the ls motor that's goin in my ef

BigMike0147

Thanks for the inside everyone. The dumptube is going to be the first thing I look into. My exhaust might get changed later on, but I should easily be able to make 300hp with my 2.5" The compression test came out great right before they dyno'd the motor 180+ across. The motor is only about a month out of build. I'm stumped, but I'm working to get the pics uploaded. Thanks guys!

BigMike0147

Looks good man! Very fresh!

BigMike0147

OK. Here are the pics. Hopefully they aren't huge or anything.

eviltek1

yea looking at the pics maybe dump tube......

Dump tube should have gone the other way toward the down pipe, your running what looks like a 2.5" downpipe which is restrictive, what intake manifold? what cams? Those ebay turbos take alot of boost pressure to make power. There crap, you can get by for now but a real turbo will make more power. looks like a combo of restriction and heatsoak. You shouldnt have 150 degree intake temps. Im in CT and on 90-100 degree days which are few and far between but my car only see's 10 degreees above ambient. IE 90 ambient my IAT are 100, 60 ambient my iat are 70 I also have my IAT sensor mounted in my charge pipe right before the throttlebody so it doesnt heat soak. When the iat heat soaks it retards the timing. Send me your bin file and ill try to take a look at it for you

BigMike0147

Yeah, I guess those are the two things that I'm going to change first is the dumptube and the turbo. I'm also going to heat wrap the dump and downpipe. I've got to get my under-hood temps down. I know the 2.5" exhaust isn't ideal but 300hp sould easily be attainable on it. I'm using stock intake and cams. I guess I will be looking to get a new turbo too before I dyno again.

If my power level is 300 whp, I'm thinking of looking for turbo that will support about 350-400. What do you think about that?? There is a guy selling a GT28RS locally, but I"m not trying to jump into anything without a good price. But I was thinking that might be a good turbo for my setup (however, I'm not crazy about how it has an internal wastegate and that it's water cooled).

I'm new to tuning, so I'm not sure what a bin file is. Are you wanting to see my map/tune, or a data log?? I appreciate all of the help guys!

To fix the dump tube if you want to be Cheap go to your local napa or autozone Or w.e and get that 10 dollar Flex pipe, weld that on and just bend it to under the oil pan or just away from that turbo intake. Gl man the rest idk what to Say best to have TurboLS help ya!!!

iTrader: (4)

Yes i would like to see your map/tune, that is called a bin file. bin is short for binary

You can email it to me maximase96@aol.com

Or you can put up a pic on here, id like to see timing and fuel

What management are you running? How far down does the dump tube go? is it past the oil pan or at least to the bottom of it?

BigMike0147

OK. I can email the tune and a couple of screenshots incase you can't open it. I'm running Neptune RTP. The dump tube stops probably just before the oil pan, but it's angled off to the side.
