I doubt they come in that size, but that's kind of a pointless size to begin with. Are you fitting these to a Dodge Viper or something? 20" rims are terrible for performance and have been shown to lose power vs 18s and 19s. No M3 I've seen thus far can fit 305s in the front, much less 355s in the rear unless they're running a big widebody.

Still sound like an 8 to me

We did a video with our BimmerWorld/Magnaflow Race Version Exhaust on our Harrop car. You definitely know its a V8. In the drive-by, you can hear the supercharger to a small degree coming toward you - it is louder inside the car, but then again the exhaust is also...

Thanks for sharing James - agree hear a bit of s/c whine on approach but there is no mistaking that V8 as it passes - neighbours must love you

We had one of the first that came into the country in 08 and several neighbors actually thanked me when we turned it into a racecar and it came off the road. I am pretty sure the blue one isn't less obnoxious... At least that was a test piece and not the normal rear section that resides on the car. But even with a quieter rear, it is still solidly an S65 sound.

Haha - I bet! Definitely makes me miss my E90 and E92 M3's!

Good luck! Will definitely stop by and say hello if I can make it out!

this totally smashes the other kits available for this car imo.

Couldn't agree more. Nothing offers the performance throughout the rev range that this kit does. No other kit fits as well, looks as good, or uses the OEM airbox. This kit is far above the rest.

Need this kit bad

Doesn't seem accurate to me...even though I see the SAE corrections and temp/humidity is noted..

Also, I understand the area under the curve plays a role, but using the first comparison, the Harrop has 29 more peak wtq than the ESS car. I wouldn't call that "gobs of tq" lol.

I also question whether that tq makes sense in a car engineered to rev to 8400 rpms, with a engine designed to have a power band in the high rpms, gearing for that high rpm car, and a DCT engineered with shifts and gear ratio's for high rpms.

It still revs out the same however I found that with the extra torque I can accelerate for example in 4th gear instead of shifting to 3rd under normal driving conditions so I'm revving the motor less unless I put the foot down

Quick question for those that may know:

I've searched here and on google for the weight of the kit with no success. Does anyone know the dry or wet weight of the kit?

ashtaron14 · 07-09-2015, 08:00 PM

75lbs. - Weigh of the whole system
20lbs. - Stock parts taken off

Just needs a stage 2 kit. Would love to see one of these running 8psi. Would be nasty.

As a side note, what kind of IATs are you Harrop guys seeing vs ambient? I've found the ESS and VF kits are around 10-15deg after starting cold and will stay that way until the coolant gets saturated with too much heat and then it goes up to around 30deg and stays there.

+1 would love to see stage 2/3 kit to compete with the other top tier offerings.

I understand direct from Harrop that Stage 2 is under testing but no release date yet. Hopefully soon but don't expect 8 psi.
