Impreza Spec C Litchfield (Almost standard) -Rolling road

Recommended Posts

Not had the car on rollers since I bought it 6 months ago so wanted to know what bhp & torque it was producing & if map looked good. Most Litchfied, Powerstation UK fuel mapped Spec C's are meant to produce approx 320bhp & thats what i would have been happy with or there abouts.

 

Though Charlie from Surrey Rolling Road did warn me that the rollers at Powerstation are of a different type & always read differently from his. Not that one is right & one is wrong its just how each is designed I imagine. Surrey Rolling Road ones read lower & they have never had a Std Spec C measured more than approx 310bhp. So I lowered my excpectations & hoped between 300 to 315bhp. Only engine mods I have is Blitz backbox (otherwise std exhaust 2.5") & Hyperflow top mount intercooler, with basic Uk fuel map.

 

My 3 quick runs later..................

To say I was happy was an understatement!! And so was Charlie from Surey Rolling Road!! Now exscuse me but I must quote his exact words just for my own satisfaction!!!!!!!

 

" As std its rare for them to make that much "...."that engine was smoooth & car ran like a pussycat on the rollers, didnt move & hardly made a sound"!! " the engine was strong & with no mods & just remap I could easliy see a lot more torque (which wasnt that high) & bhp upto approx 345 to 350bhp as is"

 

Pardon my modesty!!! :D

 

Anyway I also met Neil from Slowboy Racing who organised day & he offered great, helpful advice & had a quick look at my RR Printouts. He also agreed that torque & power could be easliy improved. As there is a flat spot something to do with AFR; & car is over fueling & it has a very moderate safe map at medium boost. I leave that to the technical geniuses to analyse the maps!! So very useful & fun morning that has given me info on which direction to go in, in terms of engine mods next year:

 

-Decat down pipe & full 3" system

-3 port boost solenoid

-Uprated Actuator

-K&N panel filter (since, done)

-Remap with new mods & hope for approx 370bhp

 

That on a 1340kg car should produce approx 250bhp per tonne & 0 to 60mph time of approx 3.8 sec ;)

 

Overall great day by MSOC & Slowboy racing, with mine producing 3rd highest figures of the day
