![]() I ordered the caps to delete the crossbars removing the sunroof baffle may prove a little harder. You may not be getting the results you're after there. ![]() Full time aero penalty for what percentage of actual use?Ī thought: propping the rear of the hood may intuitively seem like it will help exhaust air from the engine bay, but the cowl area is a zone of high pressure. Sounds like you're considering ditching the sunroof deflector as well. Do not put a bike up there! Stick it inside the car (it's a station wagon!), or get a rear rack so the bike can ride (mostly) in the vehicle's wake where it's going to have a smaller effect. I just hope it doesn't affect engine note too badly - I want this to stay the "quiet" car! I'm leaving the rest of the exhaust stock.I can't stand a car that sounds "fast" and can hardly get out of it's own way. I may pick up an OBX header.I had their downpipe on a turbo Volvo and it was actually very good quality for the money. Though, every little bit helps! I'm just knocking out the less labor intensive things first! I'll do the 5th gear at some point, but all the research I've done says it only goes from 7.55 to 7.17 - so it doesn't seem like a huge change. Ideal size, decent efficiency, and a nimble chassis. Sounds like you know the car pretty well! I'm pretty happy with it overall. The short 5th and the odd 1st-2nd gap are perhaps its only practical foibles. Probably even better if you can get a junked 626 tranny out of the bone-pickers.Ī good header could help lean things out and improve MPG a little more, but most of the good ones are out-of-production already, and all that's left are the generic Taiwanese and OBX ones. It's cheap and the benefits are pretty good. The rack/crossbars are going to stay on a little while longer (they are a PITA to remove, and I'm not certain if I'm going to use them for my bike yet). I hope to get 35mpg without having to re-gear 5th. I'll report back with the results of the next couple of tanks, and the plans for future mods. The car is full weight, with crossbars and the sunroof baffle still installed. I left the small upper grill open so the poor radiator can breathe a little, and propped the rear of the hood up (not in the pic), and removed the rear hood seal at the rain tray to allow hot air to escape more easily. Today, I installed some plexi on the front end to smooth airflow and reduce the amount of air passing through the engine bay. Not too shabby, considering the government/manufacturer claims of 22 city/28 highway/24 combined.Īnd the combined average of 26 mpg (compared to my 29.5) across the 106 Protege5's (2002 model year) tracked on Fuelly! I then installed a cone filter, and my commute changed to favor mostly highway driving - after a couple tanks, I've reached 31.96 mpg (416.5 miles on ODO, with a fill up of 13.03 gals. In all-stock configuration, and split city/highway driving, I was seeing between 26 and 28 mpg per tank, average. And since the engine in this car has NO balls what so ever, I've decided to make this the daily driver, so I can retire the Volvo to weekend/drag strip status as it runs on E85 (currently at about 390hp!). It is in "fair" shape cosmetically, but seems pretty healthy mechanically. My story with the P5, in a nutshell, is that I inherited the car from a family member who passed away. I doubt anything too extreme will happen here, but I thought I'd keep people posted anyway.
