T16-704
T16-704
Building a F7P with Turbo specs
Published by aerodynamic
29th December 2006
Talking T16-704

The spec of this engine?

1.8 16v
CR reduced to 9.0:1 with altered pistons
Fastchip ECU with mapping to 1,1bar
Renault 21Turbo fuel injectors
Renault Scenic Intercooler
Low temp thermostat
Balanced Crank and Flywheel
Garrett GT3078 Turbo on 0.6bar
Slightly ported cylinderhead

What power will it put out? The aim is to run 200bhp daily.



The base: F7P-704 engine with an broken distributionbelt.



10 damaged valves.


Like Grandma driving style......


This is much better, Bling.


Lets open the crankcase....


Slightly worn bearings, The no real damage.


Stripped the cylinderhead, Removed all the valves.


The 10 damaged valves, Nice sight.


Update:

Great Bottomend, After a paintjob it need no futher repairs.


Waiting for balanced crank and flywheel and altered pistons


Test turbo from a volvo 440. Model TB0228. Only for placement of the final turbo. Cost 50 euro.


Ran into serieus troubles. Pipes from compressor to intercooler is impossible with the starter mounted.



Homemade oil-temp-sender-oilplug. and Oilreturn


Decking the surface of the bottomend prevents gasket failures!!!



Altered and Balanced Flywheel. Right the orginal,Left the altered one. 1.3KG lighter than orginal.


New Turbo: Garrett Gt3078. Ball Bearing Turbo!


And my altered CR 9:1 pistons!



Update: 14-1-2007

what did you use to clean the engine components?

Special mixture with a steamcleaner.
And a engine wasmachine.

Ben maar eens begonnen te lezen in mijn boek: Maximum Boost - Corky Bell

Code:
 turbocharger is a simple device. It is nothing more than an air pump driven by energy remaining in the exhaust gases as they exit an engine.  Of the enegery released in the combustion process, approximately one-third goed into the cooling system,one-third becomes power dow the crankshaft., and one-third dumped out the tailpipe as heat. It iss this last third that we can use to power the turbo.
Code:
There are two ways to get more putts per minute: add more cylinders or rev the engine higher.. That leaves  lotte work with, as the whole field of endeavor known as blueprinting is almost solely for the purpose of allowing higher with some degree of safety. Consider that those nasty inertial loeds goes up with the square of the rpm inty. That means that at 7200 rpm, the inertial will be 144% greater than at 6000 rpm.
Code:
Up to the boost threshould the engine's torque curve remains virtually the same as that of an atmospheric engine. To acceleratie through this range at full trottle, the driver would feel a surge in power as the torque curve takes an upward swing at the boost threshould. If full throttle is not used, the turbo makes no contribution to the torque curve, and acceleration continues the same as with a non-turbo engine

Code:
The thermal load in an engine not orginally designed for a turbocharger will casue an increase in component and cooling-system temperatures when operating under boost.. The components and coolingsystem can handle the temperature increase for a limited period. Experience has led me to believe the time limit at full boost is on the order of 20 to 25 seconds.
Code:
Will the transmission and drivetrain be adversely affected?

Very unlikely. Consider that the drivetrain endures more torque in first gear from the stoch engine than almost any turbo engine can produce in seconde gear.

It looks to me like there'll be drive shaft issues with it

that too, if it was a sharper angle it might clear the shaft but its gona be smoking apoart from heavy braking.
