Just wanted to know if there is any word
that anyone has or is going to make a twin
turbo system for our 4.0 stangs?

 

this is gonna be hard to say without sounding like an *** (even though im not tryin to) but no there isnt, only MRT has made one, and no real plans for producing a kit.

I can gaurantee u when a company announces plans to make one, it will be all over every board in no time.

 

I heard that you can use the STS rear turbo systems in a twin configuration with some fabrication...

 

stay away from sts on a daily driven stang...beleive me, i have researched it enough to know that it would just be a matter of time before something breaks big time. it really is not worth the money at all for a tt kit on our cars...for the kinda cash a twin kit costs (gonna be 7k plus usually) you could pretty much throw some forged pistons and maybe stronger rods in the 4.0, run a single kit and rape the **** out of a twinner. not to mention if you dont install it yourself the expenses distance themselves even more. rygen says he makes peak boost by i think 2900 rpm's...? that is pretty damn good really and you could piece together a faster spooling kit if you wanted. running sts twin kits totally eliminates the main reason to go twins as they will spool right around the time of a decent single kit.

 

I'm not sure our motors & drivetrains could handle the daily use of a TT. It would be ovekill... and the motor would be whats being killed. You'd need a total rebuild of forged parts with some aluminum heads, better driveshaft, 8.5"rear. I dont think they do a 4L TT because it wouldn't stay together on a consistant basis.

 

we have aluminum heads, just an iron block which technically should be stronger than aluminum. Our heads would be fine i wouldn't worry about that. Im sure it could handle the power for a while, but there is no point. it is as you said overkill. sure you can make some great numbers with tt and get a great power curve, but for the price you could almost go built block with a different power adder and just tower over a tt kit's power. if you planned on going forged later down the road, a tt kit would be a pretty good idea as it would be a monster later on, but if you don't plan on major MAJOR work, it is total overkill like said above and not cost effective at all.

boost is boost, whether its a twin or a single.. of course a bigger compressor will flow more volume of air relative to the boost pressure. but it doesnt make that much of a difference. powerhouse is using a T61 turbo.. if you were to equal it out for the same flow with psi, i think it would be pretty close to two 14b turbo's (stock talon turbos) and their engine is a 2.4 .. if someone were to build a setup for twins, with two14b turbos or small 16g's .. can you say full boost at 2200 rpm? and it would be just as safe as the single turbo

 

like he said
peak HP will be very similar between a single and twin setup, its the curve that changes.

 

boost is boost.. correct however, I dont think he's looking to brag about having a TT pushin 7psi, he'd push the numbers you mentioned and them some for braggin rights... aluminum heads? didn't notice... thats kinda cool. I said them to help rid of the extra heat a TT would put into them.
