I have a Bushur Stage 2 setup plus a Buschur deluxe FMIC on my 9 MR. It has been properly flashed and runs well. I want to keep any combo that I build extremely street friendly. It will run only pump gas and must tolerate bumper to bumper traffic with the A/C on high. I am wondering what the gurus think of a 20gLT plus GSC S1 cams? I would do the ARP fasteners throughout at the same time I made such an upgrade. Keep in mind I have to run 91 octane here in southern AZ. I am shying away from meth injection because of the known two failure modes (mechanical pump failure and user failure).

 

Exactly what sort of flash do you have? Is it a mailin or a custom flash?

 

Great setup but do you even heard of failsafe meth???Why don't you get a GSC S2 cam??

 

What total power are you looking for? Like how much power? Sounds like you wanna keep it for the street, that's good. You're starting to approach the 'bolt-on' limits. Pretty soon you'll need to start thinking cams or alky/meth. Both are proven and safe... with the right kits/parts and careful install.

I've read the 20gLT isn't all that great an upgrade for the IX. I might be wrong, but I thought it was more meant for the VIII?

If you do GSC cams on the, they say do the S1 cams for everything < 500whp. So stay away from the S2. It's mentioned several times in the new GSC thread.

 

Do you guys have E85 available in your area? If you are unsure, you can check HERE

If you have access to E85 then I would use it. It's 105~octane for $2.20ish per gallon. The 20gLT is a great turbo. ON BUSCHURS DYNO it made well over 400whp. Convert that to dynojet and you obviously have a handfull of useable street horsepower on your hands, enough to go 10's well into the high 120's.....

As far as cams, Beings that you have a 9 you are limited to cam choice. I would go with the Cosworth cams for the Evo9. You can get them from Buschur.

 

I have a custom road flash not a mail in flash.

I can get E85 but only at 3 stations in the entire state. An E85 tune sounds like it would be very stout. But If I ever want to leave town or travel to other states, it becomes a lot of planning for E85 gas stops don't you think?

It is entirely possible that alcohol injection with what I already have is my best bet. I am leery of alcohol injection in part, because of several failures reported on this forum, in part, because of the high heat here in the summer (vapor lock is not inconsequential) and in part, because you can just forget to fill it up and have a problem. As mentioned at the top of this thread I am seeking guru guidance and not some random suggestions. I don't think the solution here is that straight forward. This high temperature, street performance requirement is not the usually upgrade path. I do have a Koyo installed to help durinig the summers here in Tucson.

I would limit my power quest to about 335-350 HP on a Mustang dyno. I am probably fairly close to 290-300 whp right now. I want to retain excellent reliability and 95% of OEM drivability. So, a big lope in the idle is out, stalling is out and a stand alone ECU is probably out. I will go with bigger injectors (680s) and any appropriate fuel system /fuel pump when required.

 

If you're leary of alky; why not do meth? Seems like a lot more people are doing the meth injection nowadays. I've seen people run around 26psi with it.

 

Your first post sounds like a very streetable setup. The alky/meth or S2 cams start to get away from a baby's-***-smooth idle or the simple, "pump and go" setup of a true street car.
