Tuning Samco vs GSR

[Todger182]

I have just got back from samco after asking to see if they would make me an induction similar to my GSR kit and I will admit myself that the kit itself looks like a very worn johnny.

Samco have said that the build qaulity of my kit looks about as good as a used condom from rough intercourse.

They said that if that gives you any performance increase they would be very suprised. Their op0inion is that isn't very well made at all, and is quite shocking.

Thought I would rant and vent myself :devil:.

Thanks

 

[dave]

well they would do wouldnt they. they will want you to buy their over engineered heavy hose.

 

[fingers99]

ith their throughput, I'd be surprised if Samco wasn't better made.

But -- the proof of the pudding is on the RR. AFAIK, Samco have no track record of producing induction kits, let alone induction kits for Centos.

You could always take one of theirs and run it against a GSR at one of oldschool's RR days.

I know which my money would be on.

At the end of the day, talk is cheap, development is expensive.

 

[Todger182]

Pic isn't very good at illustrating what I mean. I'll get some closer ones to show if anyone is interested.

My kit looks good until you get past the thinner section in the middle. In the middle it looks like it's been joined togehter and is really hard and you can also feel a ridge and past that it widens back out almost to the size of the section for the filter and slightly narrows for the TB. It stacks up quite high fowling on the bonnet and the funnel bit looks mashed on somehow.

Either mine isn't a genuine GSR kit with a GSR sticker put on or I got a dodgey one....

Thanks

If you don't like it or don't think it gives you a performance gain send it back and get your money back. who the hell cares what it looks like if it increases performance...

 

[custard]

are you asking for a direct copy or their own version?

 

[Todger182]

No I actually went to samco to see if they could possibly make a section that i can stick onto mine to enlarge it to 70mm for a bigger TB that I have coming.

They looked at the kit and asked who makes these, I just replied with GSR and they make parts for fiat and offer RR services.

I don't know if mine has any gain as I don't know the R/R before it was fitted, all I know is at the mo my car is pushing 80bhp from a mk2 punto engine.

Car has 4 branch manifold and stainless exhast system with 200 cell Cat, and at the mo a 40mm TB.

The car came fitted with a GSR already on so I would have to buy another one to see if this one is losing me power.

Thanks

just fit a standard airbox for a bit

70mm??

into what inlet manifold

 

[Todger182]

70mm down to 45mm with a shim insde for 40mm onto the manifold.

Thanks

Do you have any qualifications in fluid dynamics, because I'm not really seeing where you're going to improve performance there.

 

[Todger182]

It doesn't matter if it does or doesn't improve, i'm just testing. it's all going by favors anyway .

Thanks

 

[CLXCraig]

i'm with hellcat... that just sounds utterly stoopid. test results will be bad. sure we can all tell you that know

 

[dave]

In the middle it looks like it's been joined togehter and is really hard and you can also feel a ridge

Thanks

a rig on the out side is nothing to worry about,
there will be a ridge at the out put end so the inside matches with the tb size.
if you look at the mould it is as smooth as a glass as it should be

 

[arc]

think all you're going to see is a loss of driveability, at say half throttle you'll be giving the engine enough air to rev as high as it wants.

 

[Todger182]

If it's a loss then it will just go into the recycle bin .

Anyway after some thought i've decided to keep the GSR to one side and go with some samco 90 bends and some carbon tubing ( I really don't know why my friend says carbon fiber will be better)

He says carbon fiber internally is smooth and it doesn't attract any heat, but from what i've read to have a smooth finish inside you have to pay alot more as normally it's very rough.

Anyone know anymore on carbon fiber as it's aroused my curiosity...

Thanks

Was the GSR item developed, or just cobbled together.

Surely there must be some RR graphs from GSR to show the improvement?

Development is expensive, but not as costly as a failed product!

 

[dave]

if you join bits of silicone together with carbon or any other type of tube you get ridges, that isnt good, lots of us have tried that before

I dont think ridges are a problem Dave, my Alfa 156V6 had loads of ridges on the corner section of the induction pipework to allow movement between engine and filter. Surely if it were that bad for induction flow, they would make it as smooth as a babies bum!!!

Pic to illustrate, not my car though!!

See what i mean.

So small ridges between a carbon fibre hose and a silicone bend is negligable.

Also, just thought..... What about the big ridge between the bob abd the GSR induction kit for the SPI Cinq & Sei. That is a monster ridge!!!

Thoughts?????

Ridges like that are bad, they create turbulance in the airflow, and thus reduce efficiency.

And I have never seen a GSR in person (for obvious reasons) but as long as there aren't any ridges on the inside, then its all good. I'm thinking that the GSR doesn't have a constant width sidewall, which means that the ridge isn't carried through from the outside.

And manufacturers make compromises on many things, the Alfa induction above is an example of that
