 Posted: Fri Jan 25, 2008 2:29 am Post subject: 1915 with A1 sidewinder 1 ½ or 1 5/8 ???? new pictures |
 |
|
OK, I have a new 1915 engine with Stive Tim heads stage 2 ( 42x37 valves ), engel 110, dual webbers 44. The question is: which A1 sidewinder works better on this set up? 1 ½ or 1 5/8?
My car is 79 super cabrio weekender.
I ordered from USA 1 5/8 but received 1 1/2 if the smaller one is fine I will stay with it if not I will need to buy bigger one which means for me on another side of the pond 9 -10 weeks waiting time.

What do the exhaust ports measure on your heads? If they're not bigger than 1.5", run what you got. It's only a 1915.

I'm running a 2180 with Steve Tims Stage 2s and a 1-5/8" header.

It sounds like with those heads you'll probably want the 1 5/8" pipe. Those will definitely flow. Where do you want to make the bulk of your power? The bigger pipe might take a bit off of the low and mid-range, but will likely make a bit more power up top. Either one will work, but I'd probably opt for the 1 5/8". I have 44/37.5 valves on my 2276 and have a 1 3/4" header. I may suffer a BIT on the low and midrange, but it gave almost 10 more hp up top over the 1 5/8"

too small?
It is Serranos engine and tomorrow I will split the case to see what he put inside. I might have W125, is it better for my application? Now I have 1:1.1 rockers ( piad for 1.1:25  ) but if neede may upgrade to 1:1.25. I want as much power as possible
Thanks for your help

| I would buy the 1 5/8" since you will probably end up dropping a stroker crank in there in a year or so and then you won't have to buy a new header. If not then the 1 1/2" is perfect for your 1914 application. |

Today I would say NO, 1915 is more than enough but from what I see/read you are absolutly right.

I would wait to see what you find inside that engine, I have heard of a guy here in the uk that got a 1776 from him and when taken a part it was a pretty stock 1600.

with my longblock is not so bad. I call it LLE ( Last Limited Ldition ) I got it one week before Steve "retired". I pull the head and it is 1915 for sure.

If your going to change the cam, put a engle 120 in it, and run a 1.25 rocker.
Pump the compression to around 9.0, and run a 1 5/8 sidewinder, it will ring out a 130hp easy.

thank you Darren. I said w125 because I have it already, engel 120 will need to buy but it is not a problem. My compresion is 8,5 and I do not want to change it .
Going back to A1, I was told by the vendor that headers are measured on the outside of the tubing and if so my is 1 5/8", I thought whole my life that the dimension is messured inside.

It makes sence to measure the inside as that gives you the actual size air can flow through, if you measure the inside then you have to take into account wall thickness etc, just extra hassle.
Sounds like you were lucky wioth your engine, but i would personally strip it and inspet everything.
Serrano's retired,  I dont think most peoples see retirement as running away with your customers money.
Anyway hope the engine turns out great

I spitted the case and it look like the crank was balanced. See pictures. In the reds circles are mars, it looks like it was grinded and drilled. If the crank was balanced it was balanced without the pressure plate and pulley. Should I balance it again or it is fine? It is not going be race engine, mostly weekender with occasionally green light action.
Generally the interior looks good, well assembled. But I paid for CB lifters got something else. Can you guys recognize it? What is the other lifter? Paid for SCAT I beam rods and I have EMPI H rods.
Now I going to replace a cam as Darren suggested for W120.
