Ok, I'll point out a few things that I notice here... "90mm throttle body": They don't make a T/B that large for the Mach 1. Maybe you're thinking of a 90mm MAF sensor?

Second, the Mach 1 engine's compression ratio stock is 10.1. I'll let everyone else go into detail regarding compression rations, the stock Mach block and what's needed for a twin turbo setup.

 

yeah you were right about the 90mm MAF I was looking at both and started mixing apples and oranges, the accufab throttle body is what i was going to order i think it measures out to like twin 62mm ports or something like that.....

 

How much power do you want to make?

 

I built an up an engine for a twin turbo setup. It's expensive! Swervo has already installed a setup on his car, and loves it.

 

yeah swervo has done it, go to youtube and type in TT mach 1, he's video will come up.

the stock compression on a mach isnt good for boost, or safe for it more or less, id suggest obtaining a lower compression ratio.

the mach 1's motor isnt exactly all that good for boost in general, the crank, if your a manual mach is about the only good part of the bottom end and block

check out HP performance, there turbo kits seem to be pretty sound

 

Talk to M1M or DanB on the Mach1registry. They can give you some really good info on this. They do this for a living... when I have the funds, I'm taking mine to them for a TT setup. But I'm also going with a new engine, drivetrain, suspension, etc... everything. If you want a power adder, you need to educate yourself on beefing everything up to handle the power. Our engines are good to over 400 HP, but the internals won't be able to take much more than that (average). There are some freaks out there that manage to hold more power, but I wouldn't chance it on stock internals.

 

I would like to be able to harness at least 16 PSI boost per each turbo if thats possible, ive never done anything like this bfore so I wouldnt honestly know where to begin, what do you think is reasonable, I would like over 600 HP which i know is not hard to achieve with a TT setup

 

this is good information, thanks alot, I know wth power comes the need to upgrade lots of things with it, thanks alot for the refference.

 

ok I will def check out this video, thank you for the refference and advice

 

yup as stated that compression ratio isn't the best for turbo'd car. if you stay low boost you'll be okay, but everyone with boost knows that isn't humanly possible.

 

Hey, I'm the guy with the Twin turbo'd Mach. For turbo kits, I'd choose Hellions Hellraiser kit over the HP kit. I have the HP kit and it alright, but could be alot better. Hellion comes with everything you need, including a scavenging pump, which is a must for turbo's mounted that low.

Now for the Mach engine. You'll be fine running low boost, maybe around 7psi or so and it will be fine, with a safe tune of course. That's what I'm doing right now. The best thing would be to build a bottom end for it. Also remember to get the supporting parts for all that power you're going to have once the turbos are installed, ie clutch, fuel system, rear end, suspension...etc. All that power is nice, but if you can't put it to the ground, it's useless.

 

Hey man, saw your video on youtube through futuremach's refference, very nice car you got, as far as the engine goes when you said 7 PSI would keep me on the safe side, is that on stock internals?? also your front end, is that a completely different bumper you used for the intercooler and turbo space? mine looks different so I was just wondering if that setup offered more space to work with as opposed to stock. The last thing is could you please explain the building a bottom end ? are you talking about the rear gears and suspension?

 

Not entirely useless . . . . . spinning the tires is fun. . . .

 

lol

 

Yeah, I had over $15k invested in and engine to handle over 20psi. It gets costly when you're trying to push those numbers. If I had to do it all over agin I would've bought a preassembled shortblcok instead of starting from scratch. It's so easy to go overboard on these motors. Check out Livernois, and MMR they make some good stuff for reasonable prices.

 

HP's kit

hey, i wouldn';t recommend HP's kit. Im in the middle of installing one now. They sent watercooled turbos apparently by mistake, no oil lines, oil fittings that dont fit, no turbo gaskets, and the boxes that the turbos came in had Texas Hot Rod written on them. i have no clue why, and they dont' seem like they want to help me figure anything out. They told me to just plug the water ports on the turbos. i called garret, and they told me if i do that i'll destroy the turbo and void the warranty. it seems to be a 'nice' kit but you may have to scramble for parts. it really amazes me that they told me my turbos shouldn't have been watercooled. why wouldn't they know what they sent out? bewilderes me.

damn man sorry to hear that, i hope they get their **** straight or they wont be in business much longer. thanks for the heads up

 

well there ya go, **** the HP kit's and go with the hellion, I dont beleive its much more expensive either.

 

Don't forget the billet oil pump Swervo. I wouldn't want anyone to go through what Doc8824, and I have.

 

ok you cant put something like that up and not tell the rest of us what you went through...lol

 

The bearings in my factory pump shattered, causing my engine melted down. This was caused by a minute vibration from my UDP's it wiped out the whole lower end. I made a thread explaining it in fiurther detail.

Anyways, like I said I built a motor for a twin turbo setup, and I had $15k into it, and that was with no turbos, aftercooler, and other misc bs for the install. It can get really expensive. I had a longblock that could support over 1000hp though. I went way overkill, but it was done right. It had the best of the best parts.

 

beggining of that thread.....sucks man
end of that thread.....kick ass lol
what was the CID of the long block you built?

 

It was a 296ci or 5.0 big bore.

 

very nice, makes me wanna hold off on the mach1 and work on my 89 foxbody instead lol

 

no do the twin turbo. nothin like hearing the spool and BOV comin from a sweet stang!
