Why I picked the GT35R for my RX-7 over the stock twin turb

I cover the basics of turbochargers in simple terms to explain why I chose the GT35R over T04Z or T78 or T88 etc. It's all about air flow. Sure there are technologies that make the turbo more efficient in more applications but the turbo is most efficient in an area known as the compressor map.

Exhaust back pressure plays a huge part when dealing with quick spool small turbos.

Large turbos deal with spool up and lag (commonly description)

I chose the GT35r for near stock spool up with more efficient 400 hp generation

Lol a GT35 for 400hp? Thats no where near their efficiency range. Why didnt you go with something like a GT2876r? Or even a GTX3071r double ball bearing? Both spool faster, would easily meet your goal, and be able to build more power if you wanted. Overkill if you ask me.

@zero2skater2forever true. there is a bit of delay for the power im kicking out now. i have a 3 bar map sensor to install and get the boost up to 24PSI, but ive been busy.  So shes got potential i havent tapped into yet.

Rather than front and rear turbo I think you're referring to the primary (smaller one which spools up first) and secondary turbo charger.

@Nymphetamine2791 Right, its been a while since ive wrenched on them. Ive since forgotten which is which. The exhaust manifold makes it really easy to tell which is the low end turbo.

@emerciv thx a lot :)

[emerciv]

@markowina The quick answer to that is yes. The longer answer is: it isnt as efficient in the same budget. The thing about your first question is, the larger turbo would need energy to spool up before it begins producing boost. that is being used on the small turbo at low range. it would create a boost lag. But, if you spent thousands of dollars on the best equipment, its possible to be higher performance than a medium sized single.

hey rob.. can you make a video about how to choose turbo"s with the GRaf your talking about?

Thank you Noswolf out! plz repson

[JBMSTRIKER71]

Hey dude Look me up on dsm tuners brian o conner 420a turboed. I have spent over 15k in parts

[240sxy]

@JBMSTRIKER71 i bet you do buddy.

[jpopsbronco]

But Rob....

nvm lol

[markowina]

@emerciv this may sound stupid... but anyways..

could u stick in a smaller turbo for low rpm and a massive 1 for high rpms?

OR a supercharger and a big turbo?
