THE POWER OF R35 GTR

We have been doing many import R35GTR...modify, service etc. Today another one turn up for ...modify..This car will be more than 100ps gain at engine.....but before we do something..

Power check............we normally do power check with fully factory set up before modify.

Including this car, the power is within 5kw at wheel. 297KW~302KW so far.
"Good quality controll NISSAN"........only for this vehicle???!! wasn't that good before!!

This car made 301kw at wheel...full factory.... no mod!!

CELICA GT4......................with power FC

Not may of Celica GT4 aroud now....may be befor too....?!

Celica GT4.................... this car turned up for tuning.......looks normal from outside but....

Looks serious engine bay........this car has external gate setup with APEXi power fc......We cannot get Power FC for this car any more.........."precious"!!!

Started to tune........but feel very heavy....wonder how much power loss from drive train......maybe over 25%??..............

Result over 240kw at four wheel 1.4bar of boost.............. over 420hp at engine I recon...good result!!

TWIN TURBO EXTENTION..............

The idea is good but result is terrible.................There are many types of turbo extension (dump)pipe.....The purpose to change to this pipe is... let exhaust gas and pressure out more efficiently, Yes Most of Japanese parts are working good. However there are many copies.....



Like this twin pipe extension .............We tested without boost controller and run......the boost start from 0.5 bar(which is actuator preload) and end up....1.3 bar...........exhaust pressure build up at end...........worster than factory pipe.........minimum boost 1.3?
They are cheap...but you need to replace to another one.....wasted....



Be careful with these type.......From our test, Big single type (such as HPI or TOMEI) made more torque and better response than twin...... even better than HKS twin type......(same result for RB engine as well)..................
