I'd like to see a picture of that mani when you get it coated. I'm thinking of taking mine off and having it coated as well.

Also.....nice price on the BW362! Their diesel side of the company has great prices on the Garrett's and BW's. Is it the T4 version or T3? I definitely like the T4 version...

But i want to give a HUGE shout out to Jose at forcedinductions.com.

All i can say is wow. Awesome people.... awesome help..... awesome products..... awesome price.
I got my BW362 brand new for $830. Got it in two days and made a good friend along the way.
So thanks a lot guys.

One question I forgot to ask is, what comp cover is that for the BW362. I plan to buy another unit for my car, but don't want to weld a 90 deg elbow on the cover. That unit appears to be casted that way... Is that a special order cover and what is the outlet size??

So left is powdercoating..... new black cupplers..... a 3 bar..... lc1 wideband.....block off plates.... battery relocation..... and meth.

Anyone got any ideas were to mount the wideband gauge. i have a steering mount boost gauge..... and i like the stock look and the lc1 is the last gauge im doing so a pillar is out. But i was thinking about above the cd player whenver i get an after market one.

they have single gauge pods for the a pillar. or you could ditch the steering mount and go dual a pillar.. i would prefer to have all my gauges easily viewable at a glance.

I know but there screw in. if they had an apillar that replaced the whole thing than i would do that def.....

So ive got a question....... well actually two

My downpipe and turbo are both v band clamp. the edges that extend were they meet are they suppose to be the same size? the wholes look the same size. but one edge is smaller

and to hook up a manual boost controller dont u have to hook one end up to the wastegate and the other to a nozzle off the turbo? cuz i dont have a nozzle on the turbo

Oh and ill get pics of the manifold and dp up soon. i love em..... but my dp may not fit now so it maybe up for sell soon

the v-bands shouldnt be too far off but as long as both edges fit in the clamp it should seal. try it and see, you might have to wait a couple heat cycles and tighten it again before it makes a good seal. But as long as both edges are being clamped tight to eachother its all that matters.

You can run the line off the UIM as well. Just use one of the nipples after the throttle body as long as it sees positive pressure. There are a couple advantages and disadvantages by connecting it here.

1: the response of the wastegate is delayed, which can be good in that the turbo will spool quicker, but it can also result in boost spikes.

2: the pressure the wastgate will see is at the manifold and not the turbo. there is always a pressure drop from the turbo through the intercooler to the UIM. therefore if you have a 10 lb spring the turbo may be putting out 11 or 12 psi to make the 10 psi the engine sees, this is not really a problem because it only matters what the engine sees, but if you wanted less boost, then hooking it direct to the turbo would yield slightly less boost. Then at the UIM

yeah the UIM is the upper intake manifold. that nipple will be fine unless you have a problem with boost spikes. thats where my wastegate and EBC are tied into and i have no issues with spikes.

Made an appointment with PF supercars for Dec 28. So i will be starting the break down this weekend. Ill get pics up then too.

He said he will tune it on 22 pounds with meth, so you think its possible for around 500 whp..... he said he had just tune the same set up as me ( same 62mm Borg) except it had a ported motor, on 15.5 pounds and made 480 whp.

So get this

So i had the whole plan worked out. I had a date set with Pf supercars to get my car tuned the 28th. Well stuff came up and i didnt get done with the car. So things were going to get done and i was going to try to go up there middle of Jan.

well the other night i got in my car from eating at Taco bel, casualy drove down the road and stoped to get gas. Pull up to the pump and all of a sudden the car starts shaking. All of a sudden the vacumm on the boost gauge drops and starts shaking at around 11 or 12 pounds. I was like you got to be kidding me.....

So i did a compression test today. Def came to the conclusion that i has a chiped apex seal on the front rotor.

So now the plan is a rebuild with a mild street port by Djseven

Ahh more time and money. Got to love it.

So ive got a new question..

Im doing a street port with the rebuild now. Nothing to big, but thought still thought id do it..... but my question is how much boost am i going to be able to run?

I mean im doing meth..... and i no without it the max is around 16.

But ill prob also get a tune for race fuel..... anyone know what boost and hp i can get with it?

Well, Honestly it's a silly question, but generally speaking 15 psi is the limit on Pump though I suppose 1 psi won't make a whole huge difference. Some people have successfully ran 20 psi on pump alone, but its not recommended.

Secondly you say you're going to run meth, but you don't say if its straight meth, or an injection kit, if injection kit how much pump fuel are you replacing? Is it an HD system? You also mentioned a tune on race gas, but ???why??? if you're running meth or meth kit? Most people add AUX injection or run straight meth so they don't need race gas anymore.

So far we havn't found the limits on AUX injection and a rotary, but a few people have made over 600 HP with either meth or straight water injection. If you have a large enough turbo I suppose you could too, but you might blow it up trying to get there.

Street ports vary depending on size, shape etc. So there is no fast rull on how much gain you will have on a SP. But I would say anywhere from 5% - 20% increase, with a typical street port adding around 15% more power.

So my final answer is there are too many variables to know how much power you will make. And since you are getting it done as it is and you're most likely going to have it tuned on a dyno why not just wait and see how much you make?
