Thumbs up Crucial Racing Turbocharger porting, polishing, and coating services! <<< REALLY nice

Please E-Mail ( CrucialRacing@gmail.com ) if you have a turbo you would like done! We'll get you the shipping details and whatnot in response.

We're ready to roll out our Crucial Racing Systems turbocharger services in full force! We've been doing it on an as-asked basis for a while, and it's time to take it to the next level.

What we offer is a full port, polish, and thermal coat of both sides of the turbo. Each side gets ported by a true master, who has been doing this for ~ 36 years. He ports with the intention of improving the efficiency of the turbo, and does nothing just for aesthetics. He is capable of actually porting up inside of the 'snail' where much of the largest improvements to the turbo's efficiency come from.

After the porting is done, the turbine housing (exhaust side) gets thermal barrier coated as per our process HERE. This keeps the heat inside of the exhaust gas where it belongs, keeping energy and velocity high and improving turbo spool and response. Also, it significantly lowers the amount of heat radiated by the turbine and this drops underhood temperatures. The compressor housing is then thermal dispersant coated. This unique coating improves a metal's ability to radiate heat into the air around it (also very popular on intercoolers, radiators, oil pans, brake calipers, cylinder heads, etc). The compressor housing stays cooler because of this coating, and outlet temperatures drop. Lower outlet temps means less work for your intercooler and cooler air entering the engine. Efficiency of the turbo -- on both sides -- is further enhanced with these professional and very functional coatings. Plus.... they come out jet black and dead sexy

The gentleman who does the porting work charges $500 for this exact service for the various race teams and individuals that he does it for. Thanks to a special arrangement we have, we are able to offer the service to you for $275 to $300! The price spread is there because some turbos take longer than others and some arrive in better condition (rust, etc) than others. The only extra cost is return shipping to you.

Turn around is ~ two weeks from arrival of the turbo here to when we ship it back out. Usually it only takes one, but please plan for two just in case.

Here are some pictures of various finished turbos! ...again, please e-mail for details on how to send us your turbo for this service...


FP Green






GT 30/35/65's




....with a few VF40's from Legacy GT's thrown in for size comparison purposes...

WOW!!! Amazing Work!!!! I'd like to get my TD04 done, but I kind of need it to keep the rex running. Any kind of core exchange program???

Chris --

Not yet. Hopefully we'll be able to do that soon. However, it's not quite as easy with turbochargers to do that as it is with, for example, exhaust manifolds or TGV's. The bearing cartridges in turbos actually are wear and tear items and a core exchange is sort of asking for issues..... we'd much rather do your specific turbo and not get them mixed up because the physical state of the turbo will be known to you. Although, it would be possible for us to simply send the housings and you send your stock housings back. That way you keep your cartridge. The housings are shockingly easy to take off and put back on... anybody could do it. That's probably what would happen if we got a core exchange deal going, but that likely wont be for a while. If you really can't have your car down and really want it done, you might want to purchase a used turbo and have the service done to that. You can always then sell the other used turbo for the same amount later and not be out any money in the long term

btw -- usually I tell people with TD04's to save their money. It's such a small turbo and responds and spools so quickly as-is, that the P&P&C work doesn't make a difference that you can feel very easily. It's still good stuff, but I just don't think the bang for the buck is there like it is in basically any larger turbo (any VF-series and up). We're happy to do it, of course, but I do have an interest in helping people get the most for their $$$ and putting that much work into a TD04 might not do that.....

Good question... About ~ $80 for the turbine housing and ~ $50 for the compressor.

Prices and stuff are in the first post. It's $300-$325 depending on how much work the turbo requires. Most are $300 and it goes up if it's like super duper rusty or for whatever reason just takes more time than usual.

Quicker spool and better response for certain. Hopefully a couple/few hundred rpm of quicker spool. Engine bay temps will drop. In theory there should be a power improvement also because of the increase in efficiency and reduction in compressor outlet temps. It's hard to pin down numbers because they're small differences and the cars vary that much run-to-run on a dyno without changing a thing so when you're talking about HP that you can count on one hand it's basically not proveable or consistently repeatable. We don't market this as a power mod for that reason. It's spool and response and thermal management... But remember that a few hundred rpm of quicker spool means a bigger powerband and it does mean that you are adding significant amounts of HP in that rpm range and often it makes a touch more up top also.

One thing about Crucial Racing I have always liked, very good about giving thorough info on questions asked. Thanks for the info!!! I don't have the $ for this now, but maybe in the future.

Not usually. There isn't a bunch that can be done without actually machining them for a new plate and we don't generally do that. There are a couple companies that have exchange deals for those out there right now if you're interested. We have done some light P&P work on them just to smooth things out and optimize them as best as possible but what can be done is somewhat limited... basically I'm just not sure it makes a real world difference that justifies the cost of doing it.

I read in some other post that you are porting and coating factory exhaust manifods. Is this true? And if so, what are you charging?

Yes, please e-mail if you're interested in getting that done. We have an e-mail waiting list since we can't quite keep up with demand on them. Sorry for copy-and-pasting, but details on how it works and the current pricing is as follows:

"For the Ported, Polished, and Thermal Barrier Coated (as per our process HERE ) manifolds we usually do it as a core exchange program. So we'll get you a finished set and you send your stock ones back when you swap them. For the past eight months or so we've been working with like a month++ waiting list on them, but we're finally semi caught up and a few sets are finishing up next week, although some are spoken for. The cost for the service to the manifolds is $275. Add $15 if you want a tap for an EGT probe (and we'll ship it with a plug in the event that you know you want an EGT gauge eventually but don't have one yet). In addition, there is a $125 core fee. This fee is FULLY refunded as soon as your usable stock manifolds arrive back here. It's just to give people an incentive to send their stock ones back to us, because we need them in order to have an exchange program like this and we found that without it people simply 'forget' to send their stock ones back.

We're working on our own crosspipe, but for the time being we offer the Injen ones for $245, which includes thermal barrier coating. They're a nice piece and do make power, and our version probably wont be ready for a while... couple, maybe few, months... "

Jeremy, sorry if I missed this in your info above, but what do you charge to coat a set of aftermarket (Perrin) headers? I haven't see these yet in person (about to order them) so I don't know what the collectors look like.
Anyway, I'd be interested in just coating them and tapping them for an EGT bung (assuming that they don't need to be p&p).

Thanks.

$200 for most headers like that (that don't include uppipe... so Borla, Perrin, Gruppe-S, etc etc) as per our process here: www.crucialracing.com/products/coating.php

Every one is slightly different in terms of collectors. We have actually done a lot of P&P work on Perrin headers that come in for coating and touch up. Sometimes there are pretty fat lips inside of the flanges and the collector right before the uppipe flange sometimes has a lip and/or welding slag and whatnot. Don't get me wrong!.... they perform great and they're nice. Nothing against the product or Perrin WHATSOEVER. I try to bite my tongue in public but speaking just from a P&P perspective we are asked by customers (not us suggesting it) to do that work on the Perrin headers for nearly every one that we coat. There's usually about 30 minutes to an hour of work necessary.

Since it's stainless piping, not thick cast iron like an OEM manifold, they cannot be just drilled and tapped for an EGT probe. We actually have to drill a hole and weld an EGT bung on. Not a problem... we have stainless EGT bungs in stock and can TIG weld one on for you.

Please e-mail (crucialracing@gmail.com) for details on that stuff....

Absolutely. The 22 is a pretty old turbo in design and the castings leave plenty of room for improvement. I think this is one of those turbos where you can really get a few hundred rpm of quicker spool from a good P&P&C job.

Yes, we can TIG weld the wastegate shut for you.

If the guys who do the coating heard it called paint they would flip out . It's always black. Black is the only pigment that stands up to those kinds of sustained temperatures reliably. The dispersant is black for other reasons... but is only black as well.

Black is the new chrome

You guys seem to have a very popular Thermal Barrier Coating (TBC). I was just curious if you have any hard data of thermal conductivity, or even just logs of exhause gas temperature inside of the exhaust versus the relative temperature outside of the exhause manifold or turbine housing? How close of a relationship do you have with the producer of the coating ie: could you get a color change? What I mean by this is you will see a decrease in thermal conductivity if the coating had a higher emissivity. I'm just curious why it always seems that exhaust coatings are black when if they were silver or white they would perform even better...

Yeah ideally -- for the purposes of radiating as little heat as physically possible -- it would be a light color or, even better, smooth and glossy like chrome. We can do ceramic barrier coatings that are chrome, like in the pictures I'm going to upload.

However, the reason the coating we use is jet black is because the other coatings do not hold up to the temperatures created by a turbocharged car for long enough... they break down. The pigments can't handle it and the chrome looking coating will brown/dull and eventually fail. For a typical N/A car or a hot rod or whatever, the chrome coating works fine and is popular... it's also shiny and people like shiny .

For our cars the black works the best and holds up the best. It's still EXTREMELY effective. The company that develops the coating has spend A LOT of time and money on R&D... they employ chemists and physicists and race car drivers and spend time in the lab and on the track. I know from my times in physics classes and reading various books on these kinds of subjects that what you said is correct and theoretically it would work better, but it seems that in the real life application it doesn't pan out into very much of a difference in performance and the reliability of having it black is worth it.

For reference, going from the stock uppipe and/or downpipe to our coated uppipe and/or downpipe not only doesn't raise underhood and intercooler temps compared to the OEM parts (and bare stainless parts of this sort absolutely make temps skyrocket), it actually drops temps. A legit, large enough to easily to feel with just your face/hands when you open the hood, reduction in temperatures vs. the oem parts with all of their heat shielding.

...and another thing that helps w/ our parts is that they're made in the US of A with thick, US 304 stainless steel. Materials thickness is directly related to heat conduction and the gauge of piping in our uppipe and downpipe is WAY thicker than anything coming from China, Taiwan, and the like... and 304 conducts a hell of a lot less heat than mild steel and less than 400-series...


I know I end up getting into various talks on here with people who bring stuff from physics class and, yes, a lot of that stuff works in the frictionless vacuums where people live in the physics books but doesn't really pan out in a real life environment. That's not the case here as I believe you would see a slight reduction in radiated heat were the parts shiny or a light color instead of black, but the company has decided that it doesn't work in real life and doesn't hold up to the kinds of temps we see so hey... we're happy with the results on this end

Hope it helps! Sorry for the novel...

Jeremy



edit: whoops, pictures of the chrome coating (not recommended for any exhaust parts on our cars)
