HTA 35R really worth it?



This is AMS's vs test. Considering the boost levels this is at a much more realistic boost level for most customers I would guess 27-32 ish psi and these are the gains?

What I am asking is unless your pushing a 35R to 40+ psi or well deep into the 30's is it even worth the upgrade?

I'd love to see more info from that test like boost levels, air fuel, start rpm, etc.

I think most people get it for the fact that it spools better than a typical 35R and still has more power potential.

You have to assume everything is the same, although it probably isnt, because you will never get all that information

A 67 trim wheel in a 35R will make considerably more power than that at the expensive of mid-end.

The HTA is obviously a better turbo than the regular 35R, no doubt about that, what I am asking is at which point are they basically the same?

I would have to say it is worth it.

Ive seen some cars here lately being put out the Buschur camp that totally make me want this turbo. I know it all depends on what other supporting mods I have and I dont have enough cash for the standalone or built motor right now.

Im thinkin about picking up the cast kit (cant afford the tubular) from BR next week since its on special in their tax return sale. We'll see how the ball bounces though.

The cars you have been shown by the Buschur camp are so far removed from normally modified evo's that although they are all very impressive you cannot look at them and make judgements about how YOUR car will perform with this turbo.

DB stresses the importance of every component, if your not running buschur everything (buschur claims a 50whp decrease from running his cams to hks 280s on this turbo on full tilt on pump gas) then you will be left with "less than stellar results".

Yes DB has made a handfull of 500 whp on pump gas cars but every one of them has a 10k+ laundry list of parts from his own shop in them, most owners out there don't.

It's in line with or even slightly better than the performance-price ratio of a Cat-back, no?

For the most part (based on this graph) there's decent improvement under the curve and justifiable separation after 6k (or whatever mph translates to) for the $450 it costs. I think it's worth it.

When you have a car capable of running 30 psi and 600 whp is this where you look for 20 more?

Changing out the compressor wheel for a different one can gain you way MORE HP, at the expense of midrange/tq, i'm just torn as to whether for regular people on pump gas, or with non "BR"cars on race gas if its really all that much of an improvement.

You've hit on the answer to your own question. Everything has a certain value when compared to its alternatives. So, for $450 or thereabouts, what would the alternative graphs look like? The HTA appears to be a "cake and eat it too" upgrade which is rare at this power level and explains the expense.

Graph a 37R vs a 35R on pump gas and that is the comparison.

A twin scroll 40R would be your cake and eat it too over a 35R, or just a twin scroll 35R over a regular 35R.

Other tests show faster spool. As far as i understand, faster spool is the main reason for the upgrade for the majority of people.

Also did you ask a question or you're just looking to argue? Cause that's what it seems like.

I'm not getting that impression. Just a discussion on varying opinions.




Scorke, if you bring up a TS 35R over the standard 35 then why not add the HTA option on top of that? You'd be attempting to extract maximum performance and that $450 would be a drop in the bucket relative to the initial money spent.

Scorke isn't trying to start an argument at all and is actually raising a really good question.

From what I have seen I think it is definitely worth it. If it just made a little extra power, Id still say yes, but the fact that it spools a little faster... thats just the icing for me. If I had my EVO still, an HTA35R would be on it. Or maybe an HTA 3065!
