One man's tale of a LS1 turbo build

[Eagle]

I've actually read that very post from Rod in the past.

Also have seen that chart passed around as a possibly close representation of the PT88... but then I've heard ppl say the PT88 is capable of 132lbs/min too.

In any case, really all the reassurance that I need to have is that I've heard multiple reputable folks tell me that this turbo will be capable of 1000WHP+ which is sort of where I'm pretty sure I know I'll be content. Therefore, seems to me that the PT88 will suffice just fine without spending the extra money to get to a T6 turbo.

I just want it done at this point. The weather is getting nice outside and my car is without piping or a turbo... I just want all the parts to arrive so I can send the car over to Marty and get the piping done so it can go to Brandon so I can get busy trying to tear the rubber off the wheels.

X2. Waitin on spee Inc to get my shortblock back to me. The only other thing I van do is fuel pump install and relocate the battery.

Nice man. Can't wait to see it finished

 

[Eagle]

Finished you say?

 

[Bruce Jibboo]

lol stick a fork in it finished?

 

[Bru]

Finished you say?

With its current round of enhancements. No car is ever finished.

 

[Pressure Ratio]

Done yet? lol

Build pics?

Lets go! wtf! Tired of waiting already.

How about now?

Umm hello? Is this thing on?

I am trying to be patient but this is ridiculous.

Where are the pics already?

Stopped by their shop last night, and in true "Marty style" things are pretty damn far along for just 1 day with the car. He actually had to stop work because I had to deliver a couple more parts for him to allow him to finish the cross over and start on the downpipe.

So here's pretty much where he left off when I left the shop last night @ midnight! Enjoy!

All the raw metal parts in the pics below are freshly fabbed parts. Marty is really doing a great job. Clean and well thought out, I couldn't really ask for anything more. I'm looking forward to seeing how he handles the DP though! He's already proven that the 4" pipe won't fit through the stock K member, so looks like he'll be doing 4" off the turbo to just in front of the engine, then dropping down to 3.5" to fit through the area he has to work with. Should be good stuff.

Proof just how well the merge pieces were fabbed... there is zero gap! Good stuff This is the piece that was hole sawed out for the WG.

one more of the inside of the merge:

So far I'm quite happy. Once all the parts are done, they are going to hardway for coating, then it all goes together one final time and will need to go to Brandon to have the tune "tweaked"

I'm pumped!

what about going to an oval pipe eagle? would that help with the DP situation? Im not too familiar with F bodies

Unfortunately, its pretty much a circle hole. So unless I'm going to let Marty route it out the hood... (NO PRATT, STOP NOW! ) It's going to have to go down to 3.5".

Looking good!

Just put a aftermarket K member in it and be done with it. You know you want one and it will help out with DP room and weight.

btw, When we are out tonight introduce me to your wife as someone else. I don't want her to choke me out for giving you all these expensive ideas. hahaha j/k

The 4" off the turbo will be fine. The more strait you can give it the better. If you can fit a 4" bend that would be better than a 3.5" or 3" bend for sure. You may need a tight CLR (center line radius) bend. Basically the tightest bend you can have for any given bend is the diameter. A 4" bend with a 4" CLR. Most cheap piping is going to be a larger CLR number. It is easier and cheaper to produce. Wolfe Aircraft is where I get my tight CLR bends. Not cheap but a better product for sure.

You can also get a 4" donut that will be a 4" CLR. These are nice as you can get several cuts bend of them when you cut them up. The Pro Werks part number for mild steel 4" is C76-571. The 3.5" is C76-570.

Nah, I am not into exhaust coming out of the hood. Especially on a street car.

Oh and BTW, Screamer pipe! Race Car! haha

 

[greasy]

Shit looks fucking sexy

 

[Eagle]

Screamer pipe = WG vented to atmosphere? Whatevz man, it was that way last year too!
