actual timing spot on?

flip that turbo around and run the filter right on the housing.

is the gate open or recirc?

Sick numbers Keith!!!

DelSolMarine

what was the results of it?

I am going to take off the intake next dyno and I will have the boost controller issue I had resolved with the AMS500.

I think im a dyno *****.

the intake pipe will make you loose power? I had just filter atached to the turbo. i figured it was sucking into much hot air so installed a pipe. This will hurt my power outcomes?

i want to know this too..

flatblackhatch

numbers dont seem right the intake has got to come off you might be suprised and wrap all your piping up its just some little stuff but I'd like to know what taking your intake pipe off did for you

tony1

What size turbine housing? What size exhaust? Is there a flexpipe in the exhaust?

DelSolMarine

Tony,

I dont have the car with me at this time but I actually bought the turbo from you. I will try to find out. When I bought it you said it would support 750.

Yes there is a 3 inch flex pipe on the 3 inch 4 bolt peakboost downpipe

what is ur iat's at? I made 80whp on the dyno by removing my filter and getting cooler air in. didnt make changes to the tune.

The intake pipe doesn't cause a restriction when it's properly sized. If you have a 4 inch inlet on the turbo and your running a 3 inch pipe then you will have a big restriction. But if you have. 4 inch pipe then not much restriction at all.

To the op. We def need to know turbine housing size. And. If your running a flex section in the dp and it's not mesh inside like it is outside it's will cause a pretty good loss in power. I've seen as much as 50 whp difference between the two different flex sections on several cars

Interesting,

I too got a downpipe from peakboost and its not mesh inside, its rivetted and ****,

you think that will hurt my performance?

I have to disagree, if that is a 3" pipe with a filter on a 4" inlet turbo that is a huge restriction.

FYI a friend of mine and a mod on this site made 700+hp on the t3/t67ho with only 5psi or so more boost.

I dont know much about the BBK IM, but that could also be a problem.

tony1

I've done setups with the 3" tube on a turbo with a 4" casting compressor housing and it's been fine. Not ideal, but not a huge loss like this setup has for whatever reason. One of our full street cars has a 35R with a 3" inlet tube like that and it runs 10.1 @ 145.

DelSolMarine

I am going to inspect the flex pipe and muffler to make sure my exhaust is flowing 3 inch all the way.

I am also going to upgrade the intake to a 4" piping with the 4" velocity stack instead of the 3 inch piping with 3"stack. I will take it off at the dyno but just have that on there for the street.

the bbk IM is similar to the victorx so that is not the prob

thanks for all the input!

I am getting married and going on a honeymoon directly after so it might be a few weeks before I can get to the car or my fiance will cut my ball$ off if i change priority lol.

Don't change anything. Go to a different dyno and see if there is a difference. So many factors could cause lower than expected numbers. I would double check timing then play with cam gear timing before changing any parts. A friend of mine had a b-series with a BW 372R that was making low numbers and it turned out to be the cam timing. Of course look out for obvious restrictions like exhaust. If you have a t3 H.O. housing it is the same thing as the smallest t4. My personal car made 545whp and 331tq @ 26 but I had a t67/t3 .63 backhousing and p trim stage 5 wheel. I thought that was low and wanted more but I didn't have a decent tuner. Cam gear adjustment could have got me 20-50whp

30psi_gst

Why is this such a big deal? Its just a ****ing number, take it to the track.

1SlowSi

Its not the dyno. I thought the same thing with my car so i re dyno'd in virginia beach - same numbers.

I say this... intake needs to go bye bye and use a mesh screen
Take the dumb inline resonator / muffler out of the exhaust <---- i think its this big time
Use pure C16.

Glove

are you sure your dizzy timing is synced to 16 degree's?

DelSolMarine

sorry but i refuse to use a mesh screen

anthony your theory on this is flawed unless either the resonator or muffler is damaged (which i am going to inspect according to tony1) the 3 inch space provided is exactly that... 3 inches.

sanman000719

ive seen it asked what 4 times now with more replies than that, and he still hasnt answered yet

turbine housing? What size exhaust?

DelSolMarine

i answered tony when he asked and i do not have the car with me. I live in Suffolk Virginia, and the car is in Richmond Virginia (hometown). Talked with tony on the phone and he said ".82" to himself outloud.

30psi_gst

Using a mesh screen isnt gonna help anything. Your turbo creates a cyclone effect. If you run a screen you disrupt this entirely. If anything it will make it worse.

If your so worried about power. Cut the exhaust off right after the motor and see what it does.

You dont have to put it on the dyno to see if its making more power. Just go do a pull before you take it off. Say its 11.8 AFR. If its 12.5 its flowing more air, simple as that.

boosted hybrid

Boost leak test the car. 90% of the low power issues on turbo cars that I tune are due to poor boost leak test results. You would be surprised how many leaks you'll find even on cars making good power/holding boost.

joe111599

Thats what I was gonna say. I had a t3/t67 h.o. a few years back. I am 99% positive they come standard with .82 a/r hotside. Loved the turbo...it was a beast. Made 400whp on 12psi boost. Seen several other guys on here at 30ish psi making 700-750whp. As far as cams, I have seen guys running GSR cams making excellent power so its not your cams. Check for boost leaks then your exhaust to make sure there are no restrictions. Then maybe your turbo??? What condition is it in?

GL with everything! That turbo is badass tho for sure! ;o)

thegatekeeper14

at 30 ps1 and c16 shouldnt u be a little bit higher?
