I agree very impressive for just compresor upgrade. does the turbo have 84mm cover?

 

Are these much bigger than a BBKlite?

 

71 hta is a 51lb/min turbo, from what i understand is 2lb min more than a certain cbrd turbo but i am not sure which. In my uneducated opinion I do see the BBK's get more attention and really good results and probably due to the overall shortage of hta71's. They are becoming more popular. I have an 84mm cover on mine, and by the sounds of the 4" intake the OP does too.

robert @ fp told me that the efficicency range peaked at 23ish psi and it could be pushed to 26. His dyno results are here somewhere.. Ive exceeded that on the regular, and this uses a stock type thrust bearing. Ive experienced one failure with a oil feed line from the filter housing on this turbo. Robert copped it up to a couple different causes neither of which I was satisfied. However I was satisfied with his overall handling of the situation and while I didnt get a free turbo rebuild he did help me out considerably.

 

Ok so it's similar to the BBKfull.
It has very impressive results. I'm wondering whether I should sell my lite and get the 71 like originally intended.

 

i believe he does have the 84mm cover but ill ask him and edit this post for you when he answers.

ya id say its very similar. i think its basically a baby fp green hta.

 

I believe that Curt Brown and STM did back to back tests between the Skunk2 and the extreme intake manifold that Curt does the EVO 8/9 with the extreme out performing the Skunk2 by a good margin.

 

Tom, thanks for posting this. You dont see to many of these turbo's being posted.

would you have a similar build / fuel used, but on a evo 9 turbo?

Trying to get an idea of power gains & boost holding potential.

 

Hi Aby,

this thing is like a little fp green. i think its stronger then the old fp green.. so maybe in between a fp green hta and a oldschool green?

i can dig something up. do you want me to overlay a high power stock 8 turbo with this car or do you want a evo 9 overlayed on it?

boost holding potential, its like the bigger turbos.. it will basically run what you throw at it until it overspins.

 

an overlay of a evo9 with similar mods with a stock 9 turbo would be ideal.

trying to get an idea of what this turbo is capable of. As I know what i have been able to get from a stock evo8 turbo on my 2.3L. Using the stock turbine wheel for reference, between the oem vs hta71.

quite honestly, i really enjoy my hta-Grn on my 2.3L, but i am toying with the idea of this hta71 turbo on my 2.4L. I dont need 580whp/540tq, it's fun, but not necessary.

sorry to go off topic

 

Tom, not hating, but did you just add occupant weight to the total vehicle weight instead of adding it where occupant weight is? Since you use this program a lot, does it matter where the weight is added?

 

You are making that much with an HTA Green/2.3L combination? Whoa.

 

I'll find something for you and give you an overlay in the same temp conditions and so forth. the car here is a 8 but it wouldnt hurt to overlay a 9 with stock turbo to get a idea of the spool. if it can hang with a 9 spooling a stock turbo with mivec then its real good. i dont have any 9's with a 71hta though right now that i can think of.

yes i did, and no it doesn't effect power. its just dead weight. the graph was already posted for this car in evo 9 mode, which lowered numbers a lot because of the trans is different.

so instead of going into the cars notes i just glanced at the graph i already had posted.. since when you set the car to a new profile it reverts back to stock weight..

so i glanced at old graph, punched in total weight shown and then shared it.

his setups pretty well complete. mil.spec does a lot of testing with their evos that they dont share.. so the reason his setup can make that kind of power with the fp green is because they do their homework.

 

either a evo 8/9 turbo will work.

I thought the car was a 9.

 

Thanks!

 

I had to take another glance at this thread.

On the stock block/head and the OBX intercooler, the car made 469whp and 416wtq at 32PSI. I think this is awesome and it leaves me scratching my head thinking about what it could safely achieve at the same boost levels on a 2.4LR with all of the bells and whistles.

Would the torque come on too quickly and jeopardize throwing a rod?

What does "punched" refer to when discussing the fuel pump?
