Went to the track last night, even though it was 85 degrees and crazy humid, still ran a new .55 ar bep bolt on hx35 record.

94 talon awd
Stock auto kiggly manumatic wiring mod
Welded ctr diff
8 blade hx35
Bep .55ar bolt on housing
Gsc s2 cams
Magnus v1 smim
100% stock 6 bolt block, stock headgasket from 1990, with the exception of standard arp headstuds.

400whp/ 401wtq

10.8@126

What was the old record? Just asking cause I ran the same times @125 years ago which I didnt think was such a big deal for the size of the turbo.

11.15 no nitrous

What fuel and how much boost? Any idea on airflow (lb/min)?

Well thats pretty pathetic considering the 14b is in the low to mid 10s.

I should have posted my old time slips of my hx35 10.8 run 5+ years ago. But then again, back then nobody really cared for records like that.

Ya, 14b in full drag race mode, super light weight, on slicks and not auto... Comparing apples to oranges. Most people can't get into 12s with a 14b.

stock block and bolt ons running in the high 10's isn't pathetic... big turbo or not its still impressive as long as it isn't a chassis car built for pro stock drag .

A record is a record, whether is a drag car or a full weight street car. It doesnt matter. Throw a hx35 into a 14b record drag car and it would be the new king.

This is like that everybody is a winner mentality. Im not saying its not an accomplishment as it is a good time. Like I said , I've already ran the same time on the hx35 only 1 mph slower 5 yrs ago but Im not out to "claim" some record seeing as though smaller turbos have been faster. Run high 9's/low 10's and it will be a real feat in itself for a hx35.

Are you talking about a bep bolt on housing? On an hx35? If you are then that's impressive. If it's on a Holset hot side, they have gone low low 10s . I believe mr peepers is the quickest . This record is for the ever so popular bolt on housing for dsms

Nice grabbing my hx 35 setup next spring still haven't decided on the hotside yet.

Yea, Im talking about the bolt on .55 a/r housing. Pretty mild setup like yours and I think I was around 34ish psi e85 blend.

You on the corn?

He's not wrong.

The point was that the "14B no nitrous" record is right up there with that of a >54mm turbo at the moment. Rationalize that away however you like, I suppose. Or if it's just as simple as 'add lightness and slicks,' go do it.

Let's not pretend the bolt-on housing is super restrictive either. I was able to jam the full 65-67lbs/min my 59mm S200sx had to offer through what's effectively the same casting. Boost was 37-38psi and it maxed the drive pressure gauge I had rigged at the time, so it certainly was not the ideal housing for that application but it was not limiting the compressor in that respect.

Yep e85.
Iugrad92turbo the bep hot side is cheap and simple . If will limit you eventually but most people have no problems getting mid to low 11s on the setup with very minimal mods. I'd definately recommend it . Great street setup with full boost around 3500rpm

No the 0.55A/R BEP housing will not physically choke on an HX35.

Look elsewhere in your setup/tune.

I ran the bolt on unit, then both open and divided T3, and finally the biggest divided T4 (1.22A/R) I could get my hands on while I was experimenting with turbine drive pressure.

I never picked up more mass flow with the bigger housings, but instead returned other benefits. The casting was nearly identical for the HX35, HX40 & S200sx, just minimal tweaks to accommodate the different turbine wheels. I spoke with Bill @ BEP about this back in 2009/2010, which he confirmed.

yeah my buddy has one running the bet housing stock bottom 408 hp around there on the dyno last year here at sim sd and e 85 working on that now myself, and with new injectors and a walbro 450, the bep is a nice setup for the street my car is mostly street for now but that will change down the road. I have time to decide yet got a few things going on for the next year. His car is a blast.

Oh trust me I am with you, there's a lot of people that will tell you it will choke it out, but I think we have proven the housing is great. However mr peepers is on a stock twin scroll t3 hot side hx35 and running 10.0 last I saw. Nobody's been close to that fast on the bep. Maybe his is just a freak car but it seems to have more with the stock housing

It's the hit to VE from "excessive" drive pressure, elevated EGTs and subsequently the charge contamination from both of those. Then to deal with that situation you have to compromise on your cam choices and settings.. less overlap, tighter, shorter, etc. Acting like a smaller cam basically. You'll need to open the exhaust earlier to fight the pressure upstream of the turbine, bleeding of precious cylinder pressure that should be used to make torque. Then also will need to close the exhaust sooner, hurting high rpm breathing. Both of these things will then require the intake valve events be moved to suit them.

I was seeing nearly 3:1 at 30psi boost, and the ratio had been increasing up to the point. My 100psi drive gauge was pegged will before the intake side had the full ~38psi the compressor was feeding it.

This was with a dumped O2 and a 3" open downpipe!

That's about what my S16G setup ratios looked like, for reference.

Compare this with the HX52 on the car now, bumps just over ~1.5:1 before settling down to ~0.8:1-0.9:1 at 31psi boost by 9000rpm. Different set of cams completely, and playing with the ACGs has me gradually phasing the cams more like you would expect a nitrous motor, which she likes. Again, all a function of pressure differentials.

Funny you should mention Matt (Peepers) we were talking via PM about his setup in February.

Great work, makes the A/T more appealing every time I see these record time slips.

So, if I'm understanding you correctly, my 3.5bar MAP isn't going to be enough to log drive pressure running 30psi on my HTA68.

On a high rpm, high VE 2.0l it's likely that even a 5 bar would be cutting it close depending on specifics. Put that turbo on an R6 or my 1.5L SOHC DD and 3.5bar would probably suffice

Man I really was thinking of continuing with the 14b on my galant. But the more I read and see I really wanna run my hx35 sitting in my closet!! Hmmm

Stock converter?

I have an ipt restall . Think it would be quicker with a stock converter though. Too much slip up top, I'm hitting the limiter in 3rd at 126

How many mm is a hx 35?

56mm
