Yes sir I know that I have been defying the odds by throwing 1000+ HP at a stock bottom end and living to tell about it. The shop did an oil change while they had the car, so they cut open the filter to look for metal shavings and found none. The old 2010 lives on for another day

I will still say a good 12 rib setup with a damn strong spring tensioner is the way to go. I did finally get mine working superbly with this...but by that stage I'd already made the decision to go turbo.

But I struggled ( and had a lot of success too ) with various ribbed setups and manual tensioners, crank braces etc etc then I tried cogs, then back to ribbed...but only at the end was I able to get a tensioner setup ( and bracket adjustments ) I was happy with. And it did work faultlessly and no need to apply huge tension to the belt, as I always did with the manual tensioner.

Or if you were to go nuts with custom stuff.....a 50m cog is closer to a 14 rib in terms of width. Although belts will get harder to source for a 14 rib.
Still not sure how reliable a pair of belts would or could be...ie a pair of 7 ribs which may be easier to source.

Sounds like you went through a painful process which inevitably landed you with a turbo set up. Cant say as I blame you for the name change to Stevie Turbo . Appreciate the time you took to tell me your story!

I am currently running a 50mm cog system with bracing to keep the supercharger from flexing. There is speculation that the crank may be moving a bit under stress but honestly there is no way to tell that I know of. I don't really pound the car very often. It seems I make it to the track about every 1 - 1.5 years which is one of the reasons I had a lousy 1.6 sec 60 ft on my 10.13 sec run (at least it is lousy for this car).

I've had a lot more turbo'd cars than supercharged !. The LS is the only blower I've ever had, and what led me to do that was some videos of an old 240z, Darius with an old LT and a Procharger. The noises it made were superb.

For a long time with the YSi, I settled on the manual tensioner with moderate tension for daly/street use, and when actually racing I'd tighten it a lot more.
But annoying, but it did give a mostly reliable compromise, and lets face it, as you've seen...on the street it really doesnt need max effort anyway, so a little less tension and some slip is no big deal.

I did try cogs, but had little success, and the belts are bloody expensive to keep replacing.

And cogs will be harder on the crank and blower especially in a manual car.

I've heard of two cars in Oz that ran cogs that broke the front of a 4.0" stroker crank. All of those were also reasons I down stroker from the 4" I had, to 3.825" and then later to turbo.

Dont get me wrong through, the YSi I had was bloody fantastic and wouldnt hesitate to recomend similar to anyone. It just needs to be a blower install with a tried and tested bracket/drive system, and for me that means a ribbed setup with a real good tensioner. I like the ECS style for the Gen5 better than anything else I've seen.

What happened to Biggfoot? He hasn't posted to since June 2019. Hope all is well.

[Big Biscuits]

Yes me too. Read through this entire thread and have some great info to go off of for my FI build now. Hope he is doing ok.

[BiggFoot]

Hi guys, thanks for asking about me. I am still around but havent done anything else to the car or been back to the track so there was nothing really to report.



I suppose I did do one thing to help fix the belt issue I was experiencing. I got rid of the one idler pulley with no ridge and replaced it with a deep ridged pulley.

[racesloth]

Glad all is well! I am loving my YSi, but I need to get a smaller pulley as I am only making 8lbs of boost. A blast to drive though. I am thinking moving to 12lbs and E85 will meet all of my needs and still be in the safe zone for SBE.

[BiggFoot]

Yeah, it's been a while since I posted any update mostly cause there wasn't any new news to report.

A week or so ago I decided to take the Camaro to Houston Speedway on a Friday night. I should have known better but did it anyway. Minimum of 1 hr waits between runs.

So I am not getting great take-off's but not missing any gears and the car seems to be responding fine but my trap speed was only 135 mph with the F-1X suction restrictor out. It has been 2 yrs since I had the car to the track but with the restriction limiter in I was getting 143 mph trap speeds so you can imagine my disappointment.

Car is in the shop and they checked it out. Changed plugs/wires/oil but found nothing really wrong. 1st pull on the dyno it laid down 1062 hp but the fuel pressure was beginning to drop in the upper rpm band. That is about the only thing the shop could find wrong with the car. I know my driving sux at the track because I dont do it often, but I swear it was about the same as when I ran a 10.1 with the darn limiter in.

Anyway, long story short . . . I am having the Fore triple pump set up installed which can support up to 1500 hp so when all of the dust settles the shop is going to sponsor a track rental and I will try to get in on that and we will see if this SBE full weight fat mamma will break into the 9's. In the meantime I noticed that I am now in second place on the manual street legal fast list so congrats to SinisterZL for a great 9.812 run!

[racesloth]

Sounds good. Just need much more seat time to really "become" one with the car...

[Bildo]

I am curious as to what size your fore double setup was, I am running dual 450s on mine with 1700s as well. Kinda good to know where my limits will be.

I'm doing the same damn thing. Can't believe I didn't just get the triple right off the rip. Of course I never thought I would go this over the top this quickly but then again who does? Any time I see anyone asking about fuel systems I tell them if you need a double pump just bite the bullet and get a triple. You might not need it now, but you will.

[dreksnot]

Can't plan large enough for fueling.... (yes, I'm a mistake maker too). From LPE twin-fuel to Fore Triple 450's. 735rwhp to est 1200 on E. Supposed to be good up to 1500rwhp on E per Fore. I have not had any fuel pressure drop issues whatsoever.

[BiggFoot]

Actually I found out yesterday the triple set-up will be one 450 and two 525's - Good for 1500 hp on E-85 and/or race fuel but I only run E-85 from the pump spiked a tad with Ignite E-98.

[BiggFoot]

Fore contacted the shop after testing both of the original pumps to say that neither pump put out like it should which basically backs up the dyno.

I did not know this but E-85 will cause wear on the pump after time. The two original fuel pumps were about 4 yrs old.

I am getting 3 new pumps and a new controller, etc.

Will reload and try the strip again at some point.
