Boosted v6

[Nacho's_wit_cheez]

Wanted to know if anyone here has boosted the 3.8 and found its breaking point?

I got that snail in my avatar on eBay for 150.... It's a Holset hx52 and I want to slap it on something?!?!?!

[Det_Riot]

hahhaa my buddy had a boosted 3.8, he found its breaking point in about a day....

it was a corolla

[Nacho's_wit_cheez]

Lmao damn... Snow+boost= scrap metal

Haha guess its time to hit up google.

[Ferocious]

Bryan, is that a turd on your buddy's eye?

Breaking point for what part? Stock bottom end we say 350-360 rwhp safely no problem (assuming it's in good shape). I've seen a few go over 400 rwhp with the rest of the motor stock - but general thought is that they are on borrowed time at that point.

With a forged bottom end, we haven't found a breaking point for the stock crank or stock block. Several push 900 flywheel hp with enough fuel and boost.

I'm just looking for 300rwhp bud maybe 350, heads will be built and such I'm just worried about when the stock bottom would give.

[Number Tew]

Define heads being built?

Springs, rollers, retainers? Ported (obviously)

You'll be just fine around 300. And Roush repeated what I told you already, no issues of the block splitting on the 3.8.

It's a wicked motor, people just don't give it a chance.

[Nacho's_wit_cheez]

Mildly ported heads, cam, dual coil springs, retainers ect ect.

Lol doesn't hurt to ask. But ill take a trip to the salvage yard to see if I can find a spare engine.

[LilRoush]

I went through several junkyard sixers before fine tuning a big boost application. I found a good yard just outside Dallas that was asking $500 each for them, so I could go wrong.

[Nacho's_wit_cheez]

Haha any tips on tuning?

[Nacho's_wit_cheez]

Not looking to make big power bro just something to have fun and beat on

[Nacho's_wit_cheez]

Haha speaking of tbirds me and a friend went to pick up a supercoupe yesterday! The fucker has an 8.8 IRS setup?!?!!

[Nacho's_wit_cheez]

Lol if its like that then we swap that shit into our sn's with ease?

[Nacho's_wit_cheez]

I'll see what I can scavange up.

[LilRoush]

No, the T Bird rear isn't a direct swap. In fact, it's not worth it at all with all the fabbing you'd have to do. Even the Cobra IRS isn't a good IRS to build off of. For the cost of the Cobra IRS swap, you can make your solid axle handle twice as well.

VMP has some great tunes for the V6 and Justin can do it remotely for you as well. He's put out some serious V6 Mustangs over the years including a 10 second V6 with a stock motor with boost.

[Nacho's_wit_cheez]

Yea that's what I've read on the forums. The length of the LCA, bolt holes don't match at all, plus abs and the setup is just poorly designed from a performance view. Your better of building a solid rear and save a couple bucks.

[Silverv6]

Im looking foward to this build =] Im building my v6 for boost as well but i have a vortech =]

[330CubeGt]

Justing Starkey took his stock motor new edge into the 10s with a set of twins...

I don't agree, I come here to post because the dislike button is broken lol.

The 99-01 IRS is not good to build off of, but the 03/04 IRS will handle a ton of abuse and with little money invested.And is one of the best options out there.

[LilRoush]

I agree for a street car, it's a step up if you swap one in stock for stock.

But for a road course / handling car you have to dump $$ into them. You can get a better result out of that same amount of money put into the SRA when it comes to extreme handling. Jazzer has a great write up on Mustangforums.com that goes into deal. Shoot, the head of Griggs swapped out his IRS for a SRA on his road course car... that should say a lot right there.

Well.. If your going to boost the 6 the hx 52 is a pretty big turbo, it won't spool for crap, try lookin into an hx35.. The 52 would be an awesome choice for like a 351 or even a very good flowing 302

No way, I thought you were supposed to put the biggest turbo you could find on!

[Forcefedhatch]

If you have the proper trim turbine side you can lol.. But with a 70+trim exhaust side on a 6er it may spool but very late in the rpm range.. 4500 + lol

yea, and my valvetrain is only rated for 6800, and it's all comp (and harland sharp roller rockers) haha

Hx52 will spool fine especially if I opted out for a stroker, reason I say is because I run an hx52 on my last project which was a tiny 4L but then again I'm comparing a v6 toa v8 sooooo I'm not dead set on a turbo choice until.I do. my homework I just through the.idea of using t.the hx52 because I already have one sitting on the shelf.

Says who?

You said your only looking for 300 rwhp or so you think you would want to maximize your powerband with a small turbo that spools quickly rather than one that spools and makes power for 1000 rpms lol.

Im running a 67mm on my 4.6 and even then, I almost think a 62mm would be a better suite for a street car, and im looking at 550-600 rwhp hopefully.

That turbos way too big for your goals IMO.

[Nacho's_wit_cheez]

The more the gears in my mind turn the more power hungry I get bro. But as I said it was just a thought since I already had the turbo inhand but all and all I might just end up with a single gt35 or twin t25's and work from there.

[justinschmidt1]

Ya I mean for sure it will work but seems like you would have a lot more responsive setup with a smaller Turbo on there.

[cmsismyname]

Honestly for 300whp I would go with a supercharger instead of turbo but if you insist on going that route i'd go either single GT35 or twin T3's

[v6procharged]

i will be running a precision 6266 turbo with a t4 .81 a/r when i eventually find time to swap the kits. that hx52 is definately too big, especially for 300hp. you would have to run a pretty large wastegate to be able to keep that size turbo from trying to build excessive boost.
