Topic: Adjustable Fuel Pressure Regulator-*Updated with Results*

Ok so i will be testing one of these units soon and will give some feedback as soon as it is done.

The testbed  : My Corolla RXi

Test : Determine if there will be gains on the stock ecu with :
                            - Higher pressure
                            - Higher pressure with an ecu reset
                            - Differences in feel with higher pressure rates (2.7-4 bar)
                             -Difference with higher pressure and high flow filter
                             -Difference with higher pressure and open plenum
                             -Dyno and road testing results

Results will be in soon so watch this space guys ../../extensions/custom_smilies_2/img1/biggrin2

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

../../extensions/custom_smilies_2/img1/wink nice bro... 

ps. whats the standard pressure of a 20v?? and they 1 of the twincam series 3?

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

4AGE 20v std pressure is 2.7 bar

4AGE 16v Small port 2.55 bar

now which twincam series is 2.9 bar ???

I think the only ones that were 2.9 bar std are the 4agze ones ../../extensions/custom_smilies_2/img1/wink

Howsit bro, which afpr do you intend using, and which are decent reliable ones that you would recomend?

Hey bro dont waste your time with the cheaper ones like i did....im already having a problem. Check on the Pragia ones....especially for your turbo application. I can try and get you a price on the TRD and Denso ones if you like ?

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

Hi sam, if possible can you get a price on the trd 1 and can it be used with a standard motor?

ps. how bar is the trd 1? ../../extensions/custom_smilies_2/img1/wink

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

Yea. How much is the TRD ones?

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

Ok here goes.

Std pressure is about 2.7 bar or almost 40PSi. Here are the results :

48 PSI (3.3 bar) - There is a def increase in bottom-mid range torque but acceleration high up is slightly slower.

50 PSi (3.44 Bar) - Greater power increase in the bottom-mid

52 PSi (3.6 bar)  - Huge increase low down but the car almost hits a brick wall at about 180kph

42 PSi (2.89 bar)- Slightly higher than stock and small diff in the mid range.

44 PSi (3 bar)- This seemed to be the sweet spot with the stock ecu where the bottom?mid range power increased without sacrificing the acceleration or top speed.
I love this setting and there is a def increase in torque in the low/mid range.

It must be noted as well that when the pressure is turned up the throttle response increases greatly as well. This was an added benefit.

With regards to fuel consumption....i have not noticed any difference! ../../extensions/custom_smilies_2/img1/biggrin2

Another good bonus is that the higher pressure removes pinging on the engine. My car used to pig slightly under load below 2k rpm.....now it doesnt at all!

The next update will be with dyno graphs and power readings....BUt for now i recommend this to any 20v owner with the stock ecu. ../../extensions/custom_smilies_2/img1/cool

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

So, for me to get a 3 bar pump, or the adjustable reg and run at 3 bar, would be perfect, and get rid of my little bit of a ping issue too?!

How much did you pay for the setup?

Hmmmm..... ?!


My SigPic

Re: Adjustable Fuel Pressure Regulator-*Updated with Results*

Naa you dont need to change the fuel pump. The std 20v pump can flow just over 4 bars i think. I paid R480 for my regulator but i encourage the guys to get a better quality 1. My regulator guage is now broken and it has only been in the car for 2 weeks. I am trying to get the pricing on the TRD ones and let you guys know.
