What's power steering?

The thing that makes turning 275's easy.

I have an entire second steering rack, plus I kept all the hoses and fittings

Ah I see now. That actually looks quite clean! Have you tested them with string to see if they are effective in pulling air out?

Power steering makes the car faster, which is why I still have it.

Thinking about upgrading from ebay alu 42mm radiator to a crossflow one, what about a real comparison between 949 and TSE versions? Some experiences about?



ps. i am tracking a 1.6 gt28rs (reroute no AC) with outside temp in the 80-90 F° range and hitting 245/250 F° after 5/6 laps...

Cost is of course a huge consideration. I have no experience with the TSE rad, but a lot of people around here run the 949 and are happy with it as well, and there is plenty of track use being done with them.

Pepino

yes, also consider that i will pay italian custom fees and VAT on both value and shiping costs, adding quite as of total cost...

Both are extremely nice heat exchangers. I'm personally running the SuperMiata (949) and it's is very light. I am still tempted by the Trackspeed but have decided to fund other items since my car doesn't demand more from cooling yet

I have the TSE radiator, mostly because years ago when I bought it, the 949 one was not out. I have been very happy with it so far.

Pepino

So your opinions are that both are equivalent in terms of efficiency?

I believe the TSE radiator has higher cooling capacity which can be necessary for high horsepower turbo track cars. That is why it's more expensive. The 949 radiator is still a great radiator but is cheaper and adequate for any street car and most any track car that is not a high horsepower turbo car. I have the FM radiator because when my radiator blew up TSE didn't have any in stock and 949's did not exist. The FM radiator has also been great and I drive a turbo car that sees the track.

I haven't hit the cooling ceiling just yet, but if I take it on the track (and having kept A/C) I'm pressured into wanting the trackspeed. But I'm going to try to improvise some ducting before I switch out radiators as that would make a significant difference.

Pepino

Well i know that putting some vents on bonnet would help the efficiency but i want to keep car as "stock looking" as i can, so i was wondering to change radiator before going to vents...

Ducting and radiator will go a long way. If you're truly worried, and have the funds, just jump on the trackspeed. It will probably be overkill, but you probably won't have to revisit it. I did things backwards and if I had shrouded/ducted before, I might have spared cutting my hood.

I don't think I have seen anyone do back to back comparisons between TSE and 949. What was posted above of the differences are probably about right. For 95% of the people the 949 is probably more then adequate. For the higher HP turbo track cars the TSE is probably a bit better due to bigger capacity.

I'm still floored by how light the SuperMiata radiator is.
