Pulleys

[Banshee]

Tom,

Do you make a 100mm pulley? If so, how much?

[Tom @ Fast Forward]

I just happen to have one. I made it for test and never used it. I can let you have it for $60. Let me know

All of mine are 105mm as that is what is needed to get up in the 195/200 range. I will also be making some 110mm pulleys for those with 93/94 octane that want to get up around 210WHP.

[Banshee]

Thx Tom, I'll take it.

[Tom @ Fast Forward]

No problem. I will ship it and the throttle cable bracket together.

[Banshee]

Tom,
If its not too much to add, can you spare about 2 feet of the intake hose?
I'm going to relocate the intake if it kills me. And I can't seem to find that hose locally.


Thx.

[Tom @ Fast Forward]

Sure. No problem.

[Mathrips]

Tom I am looking for a 110 mm pulley and a 115mm pulley. Used is great. If you have either of those for sale could you tell me how much?

[Tom @ Fast Forward]

I'll take a look. I know I have a used 110mm (on my 999 right now and you can't have it :)) and a used 115mm (was on my 99 and will go back on for race days as all it needs is 94 octane to make about 220WHP. Although, when I race, I prefer to use 96 (50/50 91 and 101) just because.

For what it is worth, they cost about $10 for each 5mm increase above 105mm. I will be running some 110mm pulleys for those who want them and have 93/94 octane and 94-00 engines and I can machine some larger ones at the same time. If anyone wants them, let me know what sizes. We will be machining them the week of April 10th.

In the meantime I will look and see if I have a second set of 110 and 115 pulleys for you. I think I did?

[99mx5]

Tom is it possible to get special pulley sizes, for example a 102.5mm pulley? Just curious.

[Tom @ Fast Forward]

yes. When they are turning them they can dial in any number. 105 would be my suggested minimum for 190+.

[Tom @ Fast Forward]

Well, there are a few of them in the 05 up at the shop and I don't know the sizes. But I have a 95. 100, 126, 140 150 here if anybody wants them.

Banshee, I looked at the 100 close and it has been installed and run so it is used. Let me know if that matters. It still looks fine but you can see where the bolts were tightened.

[Banshee]

Well, since its used, I think you should include a "E-cool" package too... :wink:

J/K. No prob. I'll still take it. I'll send you a check.

[Tom @ Fast Forward]

Those 140 and 150mm pulleys are brand new. Sure you don't want to try one of them? :)

[Banshee]

Sure Tom,

I'll take a 150mm as long as you throw in your built engine with the deal...$60 sounds fair.

[Tom @ Fast Forward]

Jack in Florida is the proud owner of the engine. Guess you will have to stay with lesser pulleys. ;)

[Mathrips]

I will buy a 110 and a 115 new or used when you get them.
Thanks

Kingdon

[Tom @ Fast Forward]

What? No takers on the 140 and 150mm pulleys? :)

[Tom @ Fast Forward]

Kingdon,

They are going to make them in the next few days. As you don't have the E-Cool, I recommend against the 115 and larger pulleys unless you are running straight 101 and a BKR7EIX or BKR8EIX plug.

Of course there may be a W/A IC for those looking for a LOT of HP in a Coldside. :)

[socal pat]

" Of course there may be a W/A IC" Oh great, that's all my little open dif needs!

[Tom @ Fast Forward]

I have too many requests for 225-250WHP Coldside to ignore it.

Relax Pat. CARB comes first and the papers go out today.

[Banshee]

Tom,

Speaking of plugs, should I get your new "Plugs" if I'm going to run the 100 or 105 pulley on a 2001 with just the ELF?

If so, where do I get these plugs?

[Tom @ Fast Forward]

You can get them from NAPA. For the 01, I suggest the BKR6EIX or BKR7EIX. As you don't have E-Cool, the 7 or even an 8 might be the best.

[Banshee]

what brand is that?

[Tom @ Fast Forward]

NGK

BKR6EIX = 6418
BKR7EIX = 2667
BKR8EIX = 2668

I included the 4 digit number for you that NAPA uses. They are sometimes dense, so to speak, when it comes to finding them by the manufacturers number. If you say you want NGK 6418, they will find them easily.

[Tom @ Fast Forward]

I will buy a 110 and a 115 new or used when you get them.
Thanks

Kingdon

Just remember, about 195-200WHP is all you can safely milk out of the stock injectors. You need additional fuel from somewhere else like the 5th injector. Running anything larger than the 105 without additional fuel could be very hazardous to your engine no matter what octane. The 105 is the largest safe pulley to run without additional fuel.

[Mathrips]

Well I have all the parts for water injection either on my desk or on the way. I also have low compression pistons 9.1-1, a set of 01 mazda injectors(supposed to flow more than my 99s), a set of 310cc injectors off a toyota supra(Emilio got these to idle fine on his 99), and a walbro 190 pump. I was hoping to make it past 200whp. Maybe that is a bad idea. The extra injector idea is fine but I am still worried about equal distribution if I need that fuel for more than just cooling. Running the extra injector before the s/c seems to me would get fuel equally distributed but then I lose a lot of the cooling effect. That is what I bought the water injection for. Perhaps I am off track?

[Tom @ Fast Forward]

If you go to 310s, I doubt you will have a problem. That and WI (post blower) should easily get you well above 200. Forget the extra injector with 310s and WI. How are you going to run the 310s? I wonder if the JRPC would boost them enough all by itself? After all, it still thinks they are 240s. I'll bet with a little playing with fuel you could easily do 225 with that setup. The JRPC would probably make it too rich which is just a perfect excuse to run a bigger pulley to consume all that extra fuel. :) I wish you were over here so I could help you play with that setup.

On top of all of that, you probably have better fuel than the 91AZ oxygenated stuff we live with which would also make 225 an easy goal. Now I'm going to have to work harder on my 99. :) I still have the WI kit I took off awhile back. It was on the original prototype kit with the water pre-blower and all it did was make hot humid air (like St. Louis in summer). I only had it post blower for awhile. It cooled the air but I was ~200WHP and the stock injectors were running out of fuel so I added E-Cool and it cooled and added the needed fuel so I pulled the WI. The SS has a spare map and output to run the WI system soooooo..... hmmm.

[Tom @ Fast Forward]

I will have 110 and 115mm pulleys next week. They got the blanks in today to turn them.

[Mathrips]

I am still in for a 110 and a 115. I may not have a motor but I will have an assortment of pulleys.

[jsinnard]

What about the early BPR system with JRPC and already a 100mil pulley on a 99 with 174 rwhp? Would you recommend I can run the 105 safely? I have plenty of access to 93 octane.

[Tom @ Fast Forward]

Not without e-cool.

The 100mm on a 99 should make mid-180s. If not, there is probably something else wrong like a restrictive exhaust. I think Ari was around 182 with the ELF before they ported his blower.

The JRPC will run out of fuel top end with a 105. I wonder if the Walbro fuel pump and a pill to raise fuel pressure a few pounds would cure that? ZDoes anyone know if you can add a pill to the Walbro 255 and get more than 60 PSI on the 99+? A good question for mnet but I am not allowed to ask questions like that. :(

[jsinnard]

only running the JRPC, I declined the ELF and the porting.

hmmmmmmm....
well just curious for now

Thanks

Jason

[Tom @ Fast Forward]

Are you running the stock fuel pump?

[99mx5]

Get the ELF upgrade, its worth it.

[Wayne-n-Fla]

. I think Ari was around 182 with the ELF before they ported his blower.

:([/quote] Anyone herd from Ari on what the "porting" did for his WHP :?:

"

[jsinnard]

Are you running the stock fuel pump?

I've got a walbro 255 that I haven't installed yet and will reconsider the ELF..

Car has been running great (when I'm home to drive it). The ELF made that much difference?

[Tronman]

Tom...you get me that intercooler and I'll...well...I'll buy the thing!

Mines still running great on the 100mm pulley and 5th injector, but I think I'm about ready for maybe a 110mm...maybe add 10-15% fuel across the board...

Kevin

[Tom @ Fast Forward]

I'm running the 110 out here in AZ on 91 and about to install the 115. The 5th injector (properly located :)) is pretty good. I think the A/W IC will be 'cool' for 225+WHP though. ;)

[Banshee]

I got the 100mm pulley in. Suprisingly the belt for the 95mm fits. Just barely, but does fit.

With the 95mm, I was seeing 8.5# of boost at redline, now I'm at 10#. Don't hear any ping, but I'm a little worried that 10# may be too much without cooling. What has been your experience? I'm running 93 octane here in Texas.

[Tom @ Fast Forward]

What year?

[Banshee]

01

[Tom @ Fast Forward]

Without cooling, you are probably at your limit. We could always loan you a 105 to try if you want. I have found that 92 octane makes all the difference in the world from 91 and you have 93 so it might work?

You might also want to take a close look at your exhaust. Your boost seems a bit high.

[Banshee]

How do I look at my exhaust without actually changing it? My system is stock, never caused problems before. I have 33k miles on the car, which it fairly low.

I don't think I need a 105 pulley right now, 10# is fine right now.

I guess I need someone in Houston to loan me a exhaust to try out.

[Banshee]

There's only a few other 01+ owners out there. If I remember correctly KYP also saw 8.5# with a 95mm pulley.

[Tom @ Fast Forward]

I'll run up to the shop and grab the 05 today and re-check. Maybe the 01-05 run a bit higher? My 99 was ~10-11 with the 105mm pulley. I'll let you know later. BTW, I am about 12.5 with the 110. :)
