Yes we are an OEM Supplier to Lotus, Ford and Toyota. We know how to make bits the right way. Harrop is a 62 y/o Engineering company with roots in Motorsport. Geographically, we're a long way away however our dealer network is growing in the USA, and with impressive results all over the world, its no surprise our competitors need to market aggressively with rebates and other incentives to sell product. |

Its interesting know one has mentioned the Cosworth kit. I assume its because its more expensive but since the pound has dropped recently, isnt it cheaper now? The kit in the UK is £4k+tax so that's $4900 + shipping and taxes. So why is it still $6500 at rallysport direct?
Here in the UK the Harrop was a similar price to the cosworth kit but since the pound has dropped its more expensive by a few hundred now. |

As the OP, I appreciate you bringing up the cosworth. I didn't really consider it for three main reasons: Cost, TVs supercharger selection and packaging.
Of course, cost was the main factor. The brexit fiasco should be bringing the price down but, as you pointed out, the primary distributor in the United States has not updated pricing. The smaller TVS900 Eaton unit doesn't have as much overhead as the 1320 used by harrop/edelbrock. The rear inlet on the cosworth kit also leads to more complex intake routing and relocating the throttle body. That said, I really like the huge A/W cores used by cosworth, and the name recognition/reputation should not be ignored either. Sent from my XT1095 using Tapatalk |

After installing both kits i would like to say the following.
Both kits are on Par with an Oem quality expectation. Both kits install fairly easily, Much of it just falls right into place. The harrop Kit sits lower than the edelbrock ( a lot of people like this) The harrop kit has more access to different pulley sizes Realistically from my stand point both of these kits are great and i have yet to see and issue with either of them. For both of these kits the company's will go out of their way to help you. |

In a nutshell though, both are capable of spinning fast enough to max out their boost limit of 1.4Bar on the fa20. The 1230 will be 5% more efficient at that boost but require more engine power to spin. What this ultimately means is both will produce similar numbers. Its discussed at length with input from a few engineers but basically its was a close call but the 900 got the nod because its working smack bang in the middle of its efficiency plot in stage 2 mode which will be the most common configuration. As far as front vs rear inlet. The rear inlet was the only option when they were designing the kit. Front loading is nice that's for sure. Regarding IATs Ive been on a few trackdays with a chap with a harrop. Hes see's around +25C over ambient and I see around +15C over ambient, both at a similar power level. The engineers at Cosworth specified the cooling system to have enough heat rejection to run +25 iats at 380hp when running max boost. Also discussed was how cosworth developed the calibration which comes with the kit. They had the engine on a dyno cell, not in the car, on a proper engine test bench. They had individual cylinder pressure sensors as well as individual widebands on each exhaust port. They adjusted fueling and timing offsets to balance it all out and then set the boost level required to meet the maximum cylinder pressure determined by their analysis of the rods. They also used high end knock sensing equipment. This is proper engine development and what you will find any proper engine design house doing. You do get what you pay for, but it looks like you guys could be getting a bargain! I suspect the prices will drop when they make an order for new stock if the £ stays low. |

I love to watch Vendors dance!!!!
TRL, thanks for sharing those bullet points. There were a few that jumped off the screen if I decide to go this route.

Either way, both are reputable companies and I'd buy their products (main reason I got the Edelbrock was CARB). I'd say let's keep the "reputation" talk to a minimum and compare the two kits by definable & measurable merits ie ease of install, over all performance numbers, data logs etc. |

Competition between companies is what the market needs. We want them to make better and better products. It's healthy for the consumers.

This is true but on the internet and forums it doesn't take much for a constructive and objective conversation to escalate into a trash thread. Would really like to avoid this as I can see the embers starting to glow. Lets stay on topic and talk objectively about the products not the companies. Just to be clear I am agreeing with you

To that end, and in an effort to get things back on track, here are some of my observations related to the installation of the two kits. Keep in mind this is all based on reading installation instructions and discussions with others. I DO have a Harrop kit in my possession but have not yet done the install. These are just some of the high-points I've distilled from this discussion and my own observations so much of this has already been mentioned in this thread or elsewhere. Edelbrock:
I think those are the high points |

Unsure the installation procedure changes much either way. If you are a competent person either kit is easily self installed. The points included seem fair enough, although retaining the stock MAP sensor is a minus, as it should be replaced.
