just sad to see.

and JER. i've sat there and listened to performance industry business owners FIRST HAND and understand that competition is what makes the world go around. but when people are stealing other peoples' designs, that's just wrong. knowing it's wrong and not supporting companies like that is called having morals. i'm glad that SSAC has grown the balls to make their own designs and IMPROVE on other people's designs. that is competition. but just stealing it is just BS.



how long ago did hotshot go out of business???? were talking about 2006 or guys when did ssac header come into play? ssac to my knowlage had nuthing to do with there downfall.. and as far as i kno hotshot didnt go out of business... this is from there site..

Dear customer: Late last year I was offered the great opportunity to take a very early retirement and after careful consideration I've decided to accept it. As of April 2007, I will be leaving the automotive business to take some time off to enjoy life and my family.

Because I've been asked: Hotshot Performance, Inc. is NOT going out of business, will NOT be taken over by another company and it WILL NOT be shipped overseas. When I started my business, I wanted an All American product, and that meant it had to be built in the USA not in a sweat factory overseas or by children. That's what I believe and that's all I'll say.

During the next weeks, we will be clearing out our existing inventory by offering rock bottom prices, and once those items are gone, they will not be put back into production. Take advantage of this great opportunity to own the last of what I know is a great product at never before seen prices!

Before I close, there are two people I must thank above all: Mike Kojima and Tom Paule: Thanks for your wisdom, for your unconditional friendship for being our guinnea pigs time and again and for winning year after year! (Now we can go surf), and to YOU, our customers, thanks for your continued support. Have fun racing, and be safe!

Thanks,

John A Spangler
President - Hotshot Performance, Inc.

Keep in mind that once you put the smaller crank pulley on, the distance between your timing pointer and the crank increases enough to introduce error as you move your head around while siting the timing marks with the timing light. This factor only makes it more challenging to accurately set the timing after the pulley install.

What to do? Set the base timing before the install. Mark the distributor and housing at 15* and 19*. Use these marks for future timing adjustment -- they probably will be more accurate than any marks you can put on the smaller pulley.

If you want a backup, transfer the marks to the new pulley. Then check your base timing again and see if the marks are accurate. Make notes about how the marks calibrate and how to position your head for consistency.



or we can just put dc scottys computer and push a button to put it to the proper timing..

I'm not sure what you are saying, but there is no way to set base timing except with a timing light. All ECU timing advance instructions to the engine (i.e., the timing map) work as changes to the base timing setting, so, setting base timing where you need it is something that you want to be able to do.

sc has that nissan fast **** on his laptop.. hook it up to the car... the computer shows you what your timing is set at.. with a push of a button it puts it in timing mode.. as you advance and retard it the computer reads what your timing is at...

I think that you are talking about NissanDatascan. You are correct -- it does put the engine in "Set Timing" mode with a mouse click, but it does not read the timing. It assumes that your base timing is 15 degrees BTDC no matter what it is actually set at. The only way to set your base timing is with a timing light.

Right, the only way to adjust base timing is to mechanically move the dist. You can move the dist. to 21* base timing, and the ecu will still show it to be at 15*

WORD? i thought that the computer itself showed you what timing its at? as far as i remmember i remember him showing me a gauge that showed the timing going up and down and him telling me that the timing was around 16 degrees....

It will show the timing going up and down with throttle, but that is only accurate if the base timing is set at 15*

If just one wheel is slightly off-center or the shaft is diagonally opposed through the center of slag aluminum, with pot metal "chunks" allowed in the formula, or they dropped one, during manufacture and allowed it to be shipped anyways, then you indeed get much less quality control, than what you paid for; even at a super low price.

I don't mind supporting quality parts engineering and distributors, as long as the service is exceptional. Rarely does this euphoric ideal occur at anywhere near equal quality, service and price.

Pick 2...

1) Fast

2) Good Quality

3) Cheap

I'll take the good stuff, as long as I can get it.
My brand new strut bolts were $86.00 from Nissan.
Worth every penny for peace of mind.

Anyone here wants to sell his unmounted, machine perfect, high dollar wheelies, so they can support OBX dirt, please PM me with a reasonable price and I'll be happy to take those expensive wheels right off your hands,...

It's either "round" and "true", or it's not.
It shall remain "round" and "true", or it shall not.


thank you. this is 100% accurate. hopefully the product turns out alright but this is a pretty critical part of our car that spins as fast as our crankshaft (however many RPM's) and since the accessory pulleys are smaller, they're spinning even faster. just something to think about.

just wondering... how can anything spin faster just because its smaller? is it because ti takes a shorter time to do one rotation on something smaller then something a lil bigger right? cause i was just wondering if the crank is moving in the same speed as it was before then how would after market pullies spin faster with the same crank speed?

this is jus tme thinking out loud and brainstorming cause i have nuthing to do at work right now so its helping me stay away so this might sound stupid to you guys

yes the larger diameter the pulley is the longer it takes to do 1 rotation. the smaller the diameter the faster it does 1 rotation...

the belt has alot to do with spinning faster too, the larger diameter uses a larger belt which takes longer to do 1 rotation, the smaller pulley uses a smaller belt which does rotation faster..

besides the pulley being obviously smaller it also is lighter which gives lighter weight and less rotation mass....blah that is it is a jist i have a headache and cant put it all together right lol
