--- Quote from: r5gtt on August 03, 2016, 08:44:48 pm ---I know it not about horsey power AJP but imagine the engine spinning like a mo f* and that cam follower pumping in and out so mamy thousand revolutions per minute and there's a bigger end pushing on the follower instead of a thin piece of metal that will poke through it rather than a flat base pushing on it. This is why I'm opting for this one and not a autotech loba or APR and since I've found it I may as well give it a shot as this maybe the way forward.

Dude - the thin piece of metal pushes up and down laterally many many thousands of times a minute against the cam follower. What you want is the least 'mass' possible so there is less stress in the form of a moving mass. You do not require additional strength here. When was the last time you saw a follower wear through on the pump side? Or the internals snap due to the loads exhibited on them by the camshaft (except in cases of total failure caused through seizing which will snap ANY pump internals)?
The tolerances once fitted are the biggest concern - too big and it'll leak, too tight and it will heat seize and destroy the pump and camshaft. Without checking the pump or fitting the internals in a brand new pump you are taking a chance - nothing more or less - a chance/risk and hoping it is ok. Kinda like fitting new a new turbine and bearing in a turbo, re-assembling it and hoping it'll be ok without balancing.
The LOBA and APR pumps are assembled and checked to ensure they are spot-on. Given that the cost of these internals plus a new pump work out similar to a new LOBA it baffles me why people go down this route.

Law of averages says with the sheer number of HPFP made that a few will be defective or fail. Same story with Miltek, they make good systems but a few fail and some tar them with the sh*tty stick.
Tell me how many of the aforementioned pumps have failed in relation to the number produced/built/re built....im hazarding a guess its in the many tens of thousands produced world wide and a handful that failed, most failures are cam follower related and not pumps and of the pumps that failed how many had their internals changed by a Billy no mates in his shed.

Tell me more about Geoff :popcornsoda:...not sure why I take all trouble to travel the length of the country to see Niki when this chap is obviously better and cheaper!
(Does Geoff build pumps too?) :wink:

I know you guys are trying to help me and prevent disaster striking but the more I read into this I think it's a good idea.
Yes only two years into development but if the seller is running this without any issues this should be fine. I'd say it's like anything we'd buy off a tuner reputable or an unheard of company. people buy producys off creation motor sport and how many of you think their products have been rigorously tested?. I've brought many things off them in the past and all okay so far.
Please donr take offence as I intend to offend no one.

He tunes these engines and you want him to tune yours. There is a value in buying what people trust and have used before. I have come across tuners that refuse to touch cars with unknown/budget upgraded parts. Last thing they want is their name accociated with a blown up car after they have tuned it. You could get a generic map instead of using R-Teck as there are a lot of good reviews about Geoffs mega power remap service on line and Geoff says he does a really good job. It's only £200 as well :grin:
Every product on the market has good and bad reviews and every person selling them will say how much better their product is than everyone else's. For the want of £150 is it really worth the risk? Are you that sure you can get the internals installed that accurately you won't have issues that could cause devastating problems? There is a genuine concern that what you plan to do will turn out badly. No one wants to see you searching for a bargain replacement engine.
It's your car and do what you want to do but for £150, is it really worth it? :drinking:

Cheers mate, it's all about learning curve an all that I'd say.

Difference with CM is that pretty much everything they sell is a copy or rip off of somebody else's product, where the R&D has been done. They simply sell them cheaper as they have no R&D costs to account for, just production.
Those specs are simply manufacturing tolerances, what matters is the state of the pump they are being fitted to and how warn that is. If you fitted these internals (correctly) to a brand new pump then everything would be grand.
No offence taken, just offering friendly advice. Hope it works out for you if this is the path you choose to go down
