Last year I decided to twin turbo my 94 cobra and what a crazy experience it has been.Overall I love this thing even after all of the headaches I have gone through. Also I know that rear mount is not the most efficient way to turbo a car am still having lots of fun with it. I have put many miles on this car boosted maximum boost I have hit is a little over 15psi, Its had its fair share of problems with methanol injection and head gaskets but still it has been a great learning experience. The turbos are extremely loud and it turns everyones heads, This has been both a good thing and a bad thing with the police. Why I mounted in the rear: I did this because with my fabrication skills there was no way I would be fitting to large turbos in the engine bay. Mounting the turbos in the rear was super easy to do but did require some serious thinking as far a how to position thing and run lines. Would I mount in the rear again? The answer to that is yes, although it may be less efficient, there just something about the rear mount that I like. I couldn't tell you why but I just like it. Problems I had run in to: TUNING was very tough for me to begin with the computer does suck to tune and I have learned a lot but I am still no expert and sometimes I wish I just went with an fmu but I have gained a lot of knowlege through my many failures. right off the bat I started boosting 14psi, I blew many head gaskets in this process and it is probably a miracle that nothing has happened to the block the diy methanol systems has been a pain the ass as well. Now update: 14 psi is too much for the junk kuhmo tires my and diy meth systems has also been having problems on and off. Meth is gone,for now so I have since gone down to between 4 and 8 psi depending on who I am racing(car has been re tuned since the meth systems has broken., I am tired of going through gaskets and would like to reliably drive this car for the rest of the summer then look into doing a new block possibly during the winter. Also no I have not yet gotten the car on the dyno yet because I am planning on doing a new engine block and trans so when the build is done it will for sure get there, sorry I know everyone wants to see numbers but just be patient with me I go to school and work as well. However I know people have been wanting to hear the thing so I do actually have a small 4 psi roll on throttle pull just so you guys can hear the sound. Keep in mind I have no intercooler or meth so I'm being easy on the car until I get that fixed, and also yes I did re tune this is safe dialed back timing since my Intake temps and octane are way lower without meth. ;">[video=youtube;7ruDZ-oXHvg]https://www.youtube.com/watch?v=7ruDZ-oXHvg[/video] Also More videos are to come as soon as I get the meth taken care of, or possibly ditch the meth and go air to air intercooler? I'd like to know your thoughts on the air to air?
