Thank you for adding info into the community.

That said...Once you put information out there on the internet it is for everybody. People are going to take it and run with it. Some to your shop, obviously some to other shops.

I bought a shearer kit from a member on the boards who informed me that it was bought through buschur racing. I called (buschur) to ask about how the downpipe and the o2 housing seat (if there was anything missing) and was told "If you didn't buy directly from us don't ask"

After years of watching how people are treated on this forum by buschur racing and my experience asking a simple question about a product sold/produced by them. I will never buy another buschur product either directly or second hand.

I am sure you don't care David and that is ok.

I feel the same way when you posting information on an open public forum and complaining about what people say.

If it makes you feel like that maybe you should not be doing it. Hire someone else to be a spokesperson? Maybe then you can still do your testing and not deal with people for the most part. Might just sell more products.

Post it on your own forum if it makes you feel better.

 

I've really enjoyed reading these threads,they are way too far and few between them.

It's shame more shops don't do them, but you can the tell the one's who do because they are building more than silly youtube video cars.

 

Again thanks for your input/testing david. You have made my mind up to go for the 86HTA, currently running a 2.4LR with all associated mods with a normal gt35r with .82 exhaust housing and making 30psi by 4200rpm on a 4th gear pull. The 3076HTA would probably be a little small but good for autox and i would be a little concerned about surge.
Where do you think the sweet spot is boost wise on a 2.3/2.4 on a 86hta i've seen some good results around the 34psi mark.

 

evo4nr, you will be happy as hell with the 86 and a 2.4LR engine as long as the rest of the combo is good and dialed in.

Sweet spot on boost, hard to say, depends on fuel and the rest of the build. 30 psi works really well.

 

Yes the set-up has everything necessary to make the most of the potential of the turbo. Currently running 30psi on 94 pump fuel.
I even have a "Buschur Ported Throttle Body" quite rare in these parts!
From what i have read i shouldn't see any spool difference swapping to the 86HTA but i did assume i'd have to push the boost a little more to gain the power.

Thanks for your input and i also enjoyed your efr thread. Merry xmas

 

I'm a bit late to the party, but I do have some useful info.

Some were curious about spool time of the HTA3076R on a 2.0. I logged 26psi right at 4,000RPM with a built 2.0 on 92 octane pump gas. My turbo is a slight variation of the one David tested since it is a bolt on turbo on my Galant VR4. It has the smaller exhaust housing, but other than that, it's the same turbo. I logged a 44psi spike (on ethanol, user boost controller malfunction), that torque spike felt brutal! I had no idea this turbo liked to see boost above 35psi, it definitely gives me something to look forward to since I was out of fuel at 34psi, I just hope the smaller hot side will let it breathe up top (it only tapered 2psi from spool up to 8,000RPM).

I never would have imagined the peak torque would match peak horsepower at that power level.

 

Do you mean it is the "FP HTA DSM76" turbo?

Great results anyway!

 

Great thread

 

That would be the one

Most people on here wouldn't know what the DSM76 was, so I figured I would reword it a bit.

 

So many BR nutt-huggers in this thread, its comical. Lack of willingness to provide hard-earned information and knowledge is no excuse for unprofessional and sometimes down right rude responses.

I have no affiliation with Buschur and have never purchased anything from him and probably never will, but I don't think you guys understand how annoying it is for someone to pick your brain and want all the answers and then go buy another guys parts or purchase elsewhere to save a few bucks.

 

It is sells. Sells is 90% about the relationship and 10% about the product.

David isn't a salesman and I don't think he's ever claimed to be. Can't really fault him when his "sales pitch" comes across as anger and resentment as that's not really his area of expertise.

That's probably why he has teamed up with guys in the past that were salesmen. After a period of time though, those people find better (for them) solutions to their parts supply problems.

 

I can understand why David responded the way he did. If I was running a shop and trying to make a living selling parts I would be pretty peeved if I spent a decent amount of valuable time advising some one on a set-up only for them to spend their $ elsewhere.

The thing is, I wasn't asking for Dave to spend hours advising me on a set-up - I simply wanted an honest opinion from him on a which turbo set-up to go for.

The 30HTA has always impressed me and David's testing has helped to showcase just how perfect the turbo is for most street/track evos.
However, I would loose a lot of cash switching my stock frame turbo set-up to a full frame turbo set-up. A FP Red or Black would be the simplest solution.... I merely wanted and opinion from David if a 30HTA kit would have been worth the added cost, expense and hassle of selling my turbo set-up and buying a 30HTA full frame kit.
I didn't think I wasn't asking the moon and all I really wanted was an opinion from a man I have respect for. Dave has worked damn hard developing fast 's for many years now and it would have been cool to get his opinion. (He certainly hasn't got where he is today with his attitude alone that's for damn sure. ) Maybe I caught the mardy bugger on a bad day - who knows..... I do know I must of rattled his cage to an extent where he nearly thought throwing some written abuse my way was worth a ban from the forum! (The fact you came close Dave makes me chuckle ). It's only the internets mate - chill out! Any way for the record I've decided against the 3076HTA route and I've placed an order for a FP DBB Black (which should be with us soon hopefully).

Well all that was a little and I apologise for that.

Bringing it back on topic I would like to ask what sort of EGT temps you saw when running the 30HTA at 40PSI?

Although these sorts of threads help sell turbos, I can't help but feel they can be misrepresentational. Was that a tad harsh? Well let me explain myself....

I would suspect the poor turbo got very hot running that sort of boost for a prelonged period of time. At 40PSI the turbo has to be working very hard, well outside it's efficiency and designed operating limits - surely? I take it that this approach would only be recommended if you're out hunting down the times/records of evo powered by GT30 derived turbos - and had an understanding that operating it under these conditions would reduce the life of the turbo drastically.

I can understand why people chase records and push boundaries but I can't help find it a tad daft. Stock block record this..... stock turbo records, FP Green, Red, Black records- people are just putting their wallets on the line for bragging rights (***** waving). If you want my opinion on it - it's ****ing retarded - there I said it. If you're playing that game it boils down to 2 things: 1) MONEY & 2) LUCK.

The thing is most people aren't chasing records and a turbo should be sized correctly for the application. Perhaps a few more "real world" threads would be more useful on the forum rather than these "lets rag the **** out of the turbo and see what numbers we can generate".

Oh and to throw another comment into the pot..... I'm a firm believer that rolling roads should be used as tuning tools, not sales tools which is often the case on forums like EvoM - I'm not saying this is the case here.... just take it as a casual comment from my observations.

Happy New Year!

FP advertises the HTA30R for 40psi. The fact that it kept making roughly 10awhp per pound of boost shows that the turbo didn't mind working at 40psi. I would like to see the intake temps at 40psi though.

 

Really - they advertise at 40psi capable? Where?
Yes it is impressive the whp / psi curve remained linear especially at upper RPM's.
I guess a lot of that will be down to the map and the setup - I would imagine the main factor contributing these outstanding results is the fact it's run on E98! It would be wrong to overlook that fact and results like this clearly show the performance benefits that can be gained by running ethanol fuel. I wouldn't like to try 40psi on regular pump fuel that's for sure - would you?!

It would be very interesting to see logs for EGT's and shaft speed results too

I just wish we had E85/E98 available at most pumps over here!
