Hello All,

I have not been on here in a little while but I wanted to post something that I found on a car I was tuning.

This car setup is as follows:
Buschur Racing Built 2.3l
BR stage 3 head
BR 272 cams
PTE1000cc inj
HTA GT35R with cast manifold
AEM EMS
SMC alcohol injection 100% alcohol


This car was built by Buschur a while back and it runs awesome. The motor never missed a beat. We had a problem with the fuel pump but got it all worked out with Dave's double pumper.

This car was tuned here in Colorado so we are at about 5500ft or so. On pump gas I tuned the car to 26psi and with the alcohol on I tuned it to 33psi.

Conservative timing and AFR, we could have gotten more out of it but I wanted to leave it safe.

I have posted some screen shots of some of the logs. Check out the boost!! We are getting full 26psi at 4700 rpm, and 33psi by 5000-5200!! At this elevation that is crazy!! Car really screamed and the customer was super excited in the new found power.










I was not a firm believer in the HTA but I really think different at this point. It really made boost quickly and the car ran great.

I did not get any dyno numbers but he is going to go with an intake manifold and then it will go on the dyno for sure.

Thanks for reading,

Awesome!!!
i dont think people at sea level realize how much altitude effects turbo cars as well.
hurts spool, turbo has to work harder for the same boost and less power..

 

Very nice Mitch, thakns for helping him out on the car. He is very happy, said you did a great job. The double pumper is impressive too right?

The spool up is nice, the cast manifold helps along with the stroker.

 

Who's car is this?

The double pumper is awesome. I had no idea it would help so much but it made a huge difference Dave. Good job on building such a great motor, but I think we all know you are't too bad at that lol.

I dont have a JDM MAP or an AEM to log boost but if I watch the tach and listen for the WG and have people watching the gauges. We all agree that I get 25 psi right aroung 4600 in third gear.

I have the .63 5bolt tubular kit and love how fast it spools, faster then the bolt on 30R on a heavily ported 2g mani on my DSM on race gas running similiar to slightly higher boost.

 

Glad you were impressed with the double pumper, I know there were some questions tossed my way from the owner of the car. I told him I was confident the double pumper would straighten it out. Very glad it did.

Thanks again for making him so happy.

 

That is pretty good, is that in 3rd or 4th gear? Nice results!

 

That is in 3rd gear. It really gets moving quick.
