Hello all! Santa was good to me this year and I have decided to go with a stroker and a twin-scroll 35R. And while I'm at it, I'm getting the HTA upgrade for the turbo from Forced Performance. I was just wondering about power expectations on 93octane with meth injection. Any thoughts?

 

If everything works well together, the results should be favorable.

 

WOW Santa gave you 15 grand...

 

yeah, definitely hell of a xmas present. have fun with it man.

 

5 and change

 

all depends on the mapper! there is a thread on here about a UK guys Evo 4 built by Norris Designs that was making over 800bhp on the equiverlant to 93 octane! that was a 2.3 with a 42Rs.

with these figures and from whats happening in the UK id guys you could see over 600bhp with the best tuners.

personally though, id get them to make the power band nice and wide rather than going for something too peaky!

Ok becasue one car in UK hit 1000hp on a engine dyno doesnt mean anything unless its to the wheels. Its cool and all but who cares over here we have been there and done that almost 2 years ago.

In this case the guy wants to go with a 35R some people dont need 800whp on the street. 450-650 is just fine.

Look at it this way. Ive been in a 42R evo and i drove it for the day as soon as i hit 20psi i was already about to hit the car that was 25 cars infront of me and he was tuned for 40psi. Its pointless.

 

What have you "been there and done" in evo tuning exactly? Any pics? Any timeslips?

The UK IMHO has been well ahead of the US evo scene. All you guys in the states were seemingly stuck at 21 psi on pump for years lol until just a few months ago someone actually figured out you could do more.

The ND car you're talking about did 1000 hp at the crank. It's not amazing peak power. What I thought was interesting about it was the powerband. Nobody in the states has made a 42R with that power band on an Evo or DSM I'd suspect. If you can't respect that then oh well...

 

That's almost sig worthy...lol

 

I think there's give and take on both sides. I think a lot of engineering has been done in the USA that has trickled abroad. The US market brought a new way of thinking about the Evo, IMHO.

 

Jmartinez doesn't drive/do/have anything to show for anything, he just posts a lot in big turbo builds talking like he knows what he is talking about.

We all know he doesn't know what hes talking about if he is building a 2.3 42r evo.........

actually the 21psi thing isn't true. It was true, somewhat, for people still running the stock ecu. between 21psi-24psi was the norm for people running 93 octane on a reflash.

Dave buschur has launched a few threads recently where he's tuned people for 30psi on 93 octane but on a standalone...he even said he probably couldn't do it on a stock ecu.

Considering you're calling someone out for not having slips, etc to back up their claims, where are yours that prove the UK scene is "well ahead of the US evo scene"?

 

They have been tuning, mapping, and fabricating parts for evo's since the evo 2. The evo 8 in 2003 is the first chance a US tuner has had at tuning them.

Have we been tuning 4g63's for almost as long, yes, evos, no.

Why don't you guys start a UK Evos Vs US Evos thread somewhere else cause you guys are certainly off topic here.

I'm runnin a JAM 2.3 w/ 37R I see 580WHP (Mustang Dyno) @ 30PSI on 110 Octane. If you have done some head work I wouldn't be surprised if you have around 550.

 

Didn't mean to go off-topic but jmartinez drives me crazy sometimes!

I totally respect the US scene. Quarter mile times and parts development are really good. But I just hate to see someone say that the US was doing things 2 years ago the UK is only just doing now. It's not a fair thing to say so I jumped in.

BACK ON TOPIC...

The HTA is no miracle turbo. It will still be laggier than a 30R... and more responsive than a 40R What power you make will depend on so many things, probably most important will be the tuner. Find one that has been doing it professionally for over 7 years would be my recommendation.
