Are you saying that there are people that add nitrous kits for there cooling ability only, and don't expect or want the nitrous to go down the intake? That's nuts. Either I'm reading you wrong or you're reading AfwfJustin wrong.

 

I think what he's referring to are the NX and/or NOS intercooler spray kits, which spray the intercooler to cool down the charge even more. He's not referring to a basic nitrous setup.

 

I'm talking about the intercooler sprayer that sprays the intercooler only, not the wet kit or the dry kit that injects the nitrous inside the engine directly.

but I went back and read it again and he's basically saying spraying the nitrous at the intercooler, which makes me think of the intercooler sprayer (outside) because usually the nitrous kit that's controlled by EMS (AEM) should be wet injection kit, which shouldn't shoot through the intercooler like the dry kit.

besides, dry nitrous kit to help lag before turbo spool is just asking for it, even with MAF swapped to MAP sensor.

 

Things have changed a little since this thread started. You now have variable vane turbos, that can act like a small turbo and spool faster down low. Then at high rpm when you are moving the exhaust gases faster it can act like a big turbo and produce high pressure. Porsche and Honda/Acura both have street versions that use these. Although Porsche's is a twin turbo, I think the Acura RDX is a single.

 

When I started my new job I had a guy I work with ask me if my car was fast enough for me. I told him yeah it does pretty good. Turns out he is part owner of a local raceway that races the midget cars. He helps build engines for another guy that races up Pikes Peak in Colorado. He told me a guy hired him to rebuild an entire S2000 engine to be twin turbo. He claims the guy spent over 30,000.00 and dyno'd at a little over 700hp. He told me anything is possible but it all depends on how much you want to spend.

 

its been done before. there was a s2000 a while back that had a twin turbo setup. but, i dont know if it actually ran, it was a show car. i also dontk now if it was a sequential or parrallel setup

 

Doesn't look like anyone's brought this up yet. You would want two turbos for a V6 obviously because there are 3 cyl's on each side and airflow is not efficient if you combine them first (not to mention space for piping). This is also partially true for inline 6's (Supra, GTR) where directing airflow to one turbo form all 6 cyl's kills some of the performance. IMO flow dynamics has much more to do with a good setup than anything else. Think 4cyl log manifolds vs. horn equal length manifolds.

 

you could make 600whp with GT35 and a built block.

but efficiency and drivability is the main idea to twin turbo it.

honestly, twin turbo is twice the headache, if you ask me.
