I am going to be installing alky injection soon and maybe a few other mods. Currently I have BlueTops. I was looking at some sites and the types of injectors that are out there.
would these be a good choice for my TTA?
Siemens / Mototron
Deka 4
Flow-Matched
Sets
60 lb / hr
Injector

Depends on how fast you want to go... the ol timers and myself have a preference for 50's. Most of the alky chips will be trimmed down to 32-35 lbs per hour for a high 11 sec car. My last car with 50's in the mid 11's would run 75-80% duty cycle. The car with 65's in the 11.0 pass was running 63-65% DC.

Do the math.. a 42 lb injector would of been there. So 50's will cover ya up till high 10's easy. Since 20% of your fueling will be the alky kit.

HTH
 
would getting the 60's that i stated above be overkill???
 
Either you'll be fine. Whatever you can get a deal on...
 
I took stock injectors to 120mph with a SMC kit and that was at 25 psi. Now I have 50's that are running at 54% DC and I'm still rich with Razor's pump mod. Hopefully as I write this Eric M. is buring me another chip that will take the DC down enough that the 50's are basically somewhere between 25-28 pph. Ya see, I don't want to run more than 25psi and without throwing more air at the fuel....the mixture is WAY TOO RICH! So much so I have crazy EGT's from unburnt fuel being burnt in the exhaust thus causing the EGT's to spike and give me eronious (sp?) numbers. I even had my AFR at 11.6:1 and the chip couldn't pull any more fuel out. With that in mind, depending on who's alky kit your buying/using, I'd go on the conservative side of injector size if you plan to run alky exclusively. Just my opinions.
