I got these pictures today of my custom Spearco intercooler plumbed to the YS-Trim. Three inch intlet into the intercooler-three inch outlet into a four inch oval into the throttle body.

Don't have the flow specs on the cooler, but as you can see, it is quite large.

 

Looks Bad A$$!
That is a sweet setup. :hail:

 

Where did you get the STB from?

 

Looks good!

That STB looks like an edelbrock.

what are you going to do about the hood? It doesnt look like the hood can clear it going over the core support like that.

 

Thanks Don-your old cogs really kick a$$!

 

The back half is Ebelbrock, the cross over was custom made to clear the stealth ram.

 

Thanks Guido-you're right about the hood-but this 4" cowl works fine:

 

Thats really great looking and your car is quite impressive :hail:

I have a question for the various custom plumbing guys. Where do you get the 4inch oval to connect to the TB? I have to custom plumb my paxton and won't be using an intercooler atleast for now but I still need a 4in oval section to attach to a 3in round in some form or another. Oh yeah and what rubber pieces are you using? Where do those come from particularily the one on the oval one on the TB.
Thanks

 

maybe i will make this a post of its own

 

You start with a 4" round, and compress it into the oval. For specifics, www.cerraracing.com . They do custom turbo and supercharger plumbing, install, & tuning.

 

Glad to hear the cogs are working for you, I never had a single belt issue with them. Now the 50mm setup... that's another story . I notice you either studded the blower shaft, or you are in the process of fabricating a strut rod assy. Can you elaborate on what is going on there?
Again, I think that is a sweet setup, I am now kicking around the idea of running a FMIC. If you can, get us some temps before and after the i/c, I'd be interested in the results. Thanks DonB.

 

Sorry to dissapoint, but the pulley isn't studded, or slated for a fancy strut assembly-that is a longer bolt & spacer-the original is MIA until a replacement is found.

The IAT gauge of the DFI says below 100 degrees so far, and that is without the fan running on the dyno- I do have the Autometer 4373 dual channel IAT gauge going in soon, so I will let you know some real data soon.

 

:hail: Your car is sweet!! I look at those pics you first posted and went wow, then I checked your car out and said WOW, then I read your sig and said YEAH! Built to roadrace! Nice!!

I have a Vortech S/C too (just a S-trim tho) and I've been wondering how I'm going to plumb an intercooler. Thats a very nice install. I'd be interested to know if the car runs hotter now that you've got an IC in front of the radiator. I've been thinking about adapting the ATI twin IC setup Willie designed to a Vortech S/C but only because everyone says you cant put anything in front of the radiator. I'd prefer to just have a single IC.

Nice Ride Brah!!

 

Crazy-thanks for the :hail:

I had two small Spearco intercoolers mounted low, but they just didn't move enough air to keep up with the YS Trim. I haven't had it on the track yet-that will happen at the RA F Body event April 12 & 13th. I do have a mechanical fan and custom shroud along with the BeCool radiator, and Edelbrock aluminum pump. We'll see if it stays cool on the road course!

 

that setup looks awsome, I bet if another inlet were placed on the top tank for the pass side then a twin turbo car could use one like that.

 

Ya but then you'd have to use an aftermarket pin on hood

 

When you order a custom intercooler, you can specify the inlet/outlet locations, size, etc

I was wondering where that pulley went off to I originally had that cogged crank pulley and I traded it in for the standard (non-underdrive) crank cog pulley. Also had Don fab me up a billet bracket to prevent the flex of the stock bracketry ....

One day I'll get that YS ... it will just be awhile I really love what you did with the intercooler. I might have to imitate you one day.

Tim

 

I noticed in your pictures that you have the ground control caster camber plates. How do you like them? I am going to make a set for myself and I was wondering if you have and more pictures of them besides what are posted on your site?

 

TRAXION, Are you sticking with the stock ECM with the YS-Trim?

 

Yes. I'll be running the stock ECM repinned for a 749 with $58 code. I have an Accel Variable Injector Controller that I picked up really cheap that will allow me to run low imp injectors ... that will allow me to go big on the injectors.

Tim

 

Thats cool. I can't wait to see how it turns out.

 

No-don't have any other pictures. The car is at Cerra Racing in Rock Island-stop by and take a look

 

Will your car be there all week and when are you going to be there I would like to meet the man behind the machine. bbunting can you give me your name so I don't feel like a total idot when I ask to see your car. Send me a email if you like, I wouldn't post this but I don't know how to get ahold of you any other way.

 

you have a PM

 

Don- ran on the dyno Saturday. New results with 12 lbs. boost:

649 RWHP 580 RWTQE gas only

Max IAT 95 degrees off the DFI after the intercooler at 6800 RPM and 12 pounds boost. That was with the fan in front of the radiator. I will hopefully have the gauges hooked up soon so that I can give you before and after temps. I will also dyno after I get another small pulley without ribbing so that I can get back up to the 16-18 lb. range.

 

:hail:

Tim

 

Sweet numbers!
It will get real interesting when you get "real" airflow across that I/C. Didn't you have a 29 tooth pulley for the s/c? that should put you in the high teens (17-19#). I am now curious as to what pulley combo you have now to get 12psi. Currently I have a 77/29, and I am expecting to see over 20psi. if you are running the 75/29 and only seeing 12psi.... I guess I am in for a bit of suprise.
Either way, you are getting great results from that setup, and I am always looking for these updates. I am glad everything is working out so well for you, that Y/S is doing the job!
:hail:

 

bbunting,

If you want a pulley capable of putting out more boost I think I have the smaller blower pullies? Don would know for sure but I thought that I did? I'll count the teeth on the pulleys later if you are interested.

Tim

 

I think I was wrong. I probably have the bigger SC pullies. I have the 33 and the 35 tooth pullies.

Tim

 

The pulley I used was a 75/32 tooth cog-the largest Vortech sells. I wanted to tone it down a bit after replacing the head gaskets twice. The pulley I got from you did make over 20 PSI before I had the heads cut for the Felpro gaskets. Also not sure how much more boost I feel like running in a .070 production 350 block!


EDIT-we might have made more power if the Centerforce DF clutch would have held up-smoked pretty bad. Anyone recommend a clutch?

 

I e-mailed the Summit tech line a few months ago and asked what they recommend for a clutch setup for my application. I asked specifficlly if the DF would hold up. They said "no way" and pointed me to the Mcleod Street Twin. So that is what I have now, the billit aluminum flywheel model. It's not a drag car so I didn't need the extra inertia of the steel.

 

Ordered the SPEC Stage III ceramic package. After talking to their tech line about my aplication, that is the route I took-gets delivered Saturday. Hopefully have the clutch installed this weekend and get some real world intake air temps while breaking in the new clutch-even though it is only 35 degrees here.

Here is some real world driving data after the new intercooler install. Ambient temps today 75-80 degrees.

Highway cruise at 2500 RPM

Blower discharge temp 100

Intake manifold temp 88 (back of intake manifold)

4th gear WOT from 3500-6500 RPM

Blower discharge temp 120

Intake manifold temp 99

 

Looks like you dropped a constant 20* across the board. That is good info to refrence the results of my air to water i/c.
I can't believe how low your outlet temps were, that is great! I have seen outlet temps higher than that with an S-trim. That makes me happy
Thanks for sharing your results, DonB

 

Don- I will get you some more results the 12/13th at Road America. I will have a passenger that can log all the temps during warm ups lap (WOT thru 2,3,4, & 5th gear). But the large single is much better than the two small Spearcos.

 

Ambient air temp-40's
Humidity: 60%
Max temp at blower discharge: 180's
Max temp at intake manifold: 150's

Taken at the end of the straight in fifth gear at 5400 RPM
(160 MPH)

 

wow. thats lower than my roots blower's outlet temps after only a short 0-60 (6000) rpm run through 1st gear!!!

 

B, I am glad to hear the temps are so low with that y/s-trim. I am hope to have mine running soon, and would be thrilled to see outlet temps that low!
Thanks for the update. I'll let you know how mine turns out when I'm finished with it, although mine is a straight line runner.
BTW. 160mph is sick! :hail: Hopefully I can trap @ 150mph in the 1/4, but I just can't immagine what 160 must feel like. You are the man! Keep us posted.
Don B.

 

Here are some top speed shots for you-more to come;

160

160 II


One thing that helped the temps is that I have the air intake routed under the front fender-so it is breathing fresh cool air-not under hood heated air. I'll post some pics later.

 

Sweet footage!

 

I agree! Kickin some ***!

 

Here are some pics of the air intake for the supercharger. The hose has wire running through it to prevent collapse-even though it does compress if you give it too much slack-under the car is a 4 inch round K&N cone filter pulling cool air from under the fender-the fender brace needed a little "massaging" with my BFH, but it seems to work well. Also snapped a few new shots of the interior gauges, seat, new Grant wheel, etc

 

Here is a little close up of a 0-100 dash out of the grid.

hey what does your fuel economy look like, and do you drive the thing on the street much?

72pph injectors are huge! how do they do around town? no problems controlling them?

 

Haven't really measured MPG yet. It really runs fine as long as your maintain 2500+ RPM-otherwise the cam doesn't like it. Runs down the highway at 65 MPH with no problems.

PS-72's aren't that big-they are almost maxed right now. I am looking at 96's.

 

Yeah, can you figure out your fuel economy for me... Race gas is expensive, and I don't want to buy a whole bunch.
PS. Don't listen to me, I'm just being a d1ck!

 

Don- I can tell you that it drinks 110 leaded Citgo by the barrel. $3/gallon.

 

Yeah, I know what you mean, I am running VP C-16. It is $30 for 5 gal... that works out to be 6bucks a gallon
I am going to have to break down and buy a 55gal drum one of these days, might save a buck or 2.
