Engine/Transmission (1998.5 - 2002) Mach 6 with a single charger

[FUL POWER]

Can you run Mach 6 injectors with a single charger and what size of a charger would you need to run them and try to keep the egts in check.

 

[Hohn]

Certainly. Just not a small one



Obviously, you've been surfing the Net, and you see in the description of Don's M6's that "twin turbos only need apply", right?



Well, that was written quite a while ago when, in fact, there weren't any single turbos on the market that really could handle them, in terms of EGT.



But things have changed a lot in just the last 1. 5 years or so. There are plenty of guys running them with larger single turbos. Especially sledpullers that are limited to a single turbo by class rules.



A turbo like a full-on B1 or a Super Phat Shaft 66 or a Sledpuller 66 should accomodate an injector this large if that's the route you want to go.



Be advised that it can be a little laggy (and thus, smokey) on the street.

A little laggy is an understatement. I would think that you would need at least a B2 to get enough air for all the fuel that they can put out.

 

[Bandit1]

jsut to add, my phat shaft is far from laggy, it spools faster then my old pdr 40. to give a comparison

Can you fill in your signature so we can see what you have? If you have an H. O. you won't be able to utalize the potential of the mach 6's with the stock VP44. You may already know that though. .

I have a friend who rund BD8's/drag comp with a HTT SP66 and he clears up pretty good once he blocked the wastegate. Around down on a hot humid day it is very hazy but he is running a tight automatic. I would think the M6's should be cleaner down on the bottom. In a nutshell I would not be afraid to do it, but they are right, a SPS66 or HTT66 would be about the only charger I would run with an automatic. I think the B1 would not clear it up on top.

Oversized B-1, Mach 6's, Redline Box, Comp Box (no pump wire attached) = 610 RWHP.

I'm running 6s and a regular 66 from Shane. Keep in mind I'm at ~5500'. They definitely added some power but they are hard to drive even with the Comp turned down and not blow clouds. Don't get me wrong it can be done but if you are not patient with the right foot, you won't like it. The 66 just doesn't seem to work that well on my VP truck. I know there are lots of folks running them on the CR trucks and they work fine but on mine it's laggy. It cleans them up to a haze when it does get going but you have to baby foot it off the line or it's midnight time lol. Shane, is going to build me a 64 and we'll see if I can get something that will light a little quicker and still cool ok on top. To answer your question, yeah you can run 6s with a single but I think I liked my 4s and B1-2 better than my current setup. Nearly as fast and actually a lot quicker. They lit off that B1-2 300rpms sooner, ran cooler, and were less smokey. Of course what else would you expect right... Bottom line that is a 500+hp sweetass setup if you ask me. If we can get a turbo that will light at 1750-1800 instead of 1950-2000 and still clean the 6s up ok then maybe my opinion will change. I'm going to dyno this setup here in a couple weeks with water/meth and we'll see if it can eclipse the 600 barrier.

 

[FUL POWER]

what are you temps like. I have a 64mm and im thinking about running a 66mm or even a new 68mm that is comming out. But there is going to be some lag. Howis you MPG wiht the mach 6.

 

[Luke Warmwater]

3x5 it maxes at about 1375 or so. 5x5 It will get to 1525 on a nice long 5th gear pull. I'm ok with those temps but not with a laggy turbo. IT's one or the other. Give something that will light around 1750-1800 and 1500 is fine. If it's not going to light until 2000 then 1500 is too hot for me. Which 64 do you have and which turbine housing? Where does it light with your current setup and what is your current setup? Thx



Doug, where does that Steroid light at? I finally gave up them guys. Having a B1 on order since April and it's now Sep is BS. TAD is a crappy ran business I'm sorry.

 

[FUL POWER]

I have a HTT 64mm and a 14cm exhaust with jammer 5 i see 1400 on 5x5 with water/meth pulling a sled in 3 or 4 gear depending on the track. The turbo light fast wiht not muck lag. ever day driving i see 800-1000 70MPH 600-700 55mph but i never fo that slow. have you dyno your truck to see what it makes. I made 535 hp and 1199 torque

 

[Luke Warmwater]

So you have a lot of variables there lol. What does it do on 5x5 unloaded on a 5th gear pull? If we're going to compare numbers then let's try and do it with equal setups. I don't really concern myself with what it does pulling my sled trailer as I can turn down the comp and take it easier if I have to. I'm curious with these questions regarding your setup...



What altitude are you at?



What is your max boost?



What are max EGTs unloaded on a 5th gear pull without water/meth?



What are max EGTs unloaded on a 5th gear pull with water/meth?



What are the rpm's where the turbo begins to build boost(1-5psi)



What rpm's does it take off from that intial boost level to 20-30-40?



My 4s and a b1-2 made 514hp. I'd expect the 6s with the 66 to be up 575-600. I will know on Oct 1st when I get it on the dyno.

Thx

 

[FUL POWER]

Altitude is 647. 7

max boost 45

1600 with the pedal held to the ground 125 MPH

1400 with water/ meth 50/50 gained 30HP

1500rpm

dont know

I made 535 1199 on a 96 degree day wiht 90 percent HUM

 

[Luke Warmwater]

Interesting! So it sounds like with the 6s and a 66 that it may be a little coooler on top. 1500-1525 is as high as I can make it go even with 35" tires wfo. If you start making boost at 1500 that is pretty close to where my b1-2 would start going. because of that it would pull hard out of the hole without much smoke. With the regular 66 which I understand to be about like the SP66, it really doesn't go until 1900+. That makes it a total pain in the rear to drive and not much fun. I bet you could run 6s with your current setup and not gain much if any in temps and might in fact even go down a little. Shane is going to build me a 64 to try and we'll see. I'd rather have higher temps on top but something that goes hard in the mid range. My guess is that you won't care much for one of the 66s if you are used to something that comes in at 1500.

 

[FUL POWER]

I need to get some mach 6 to try and see and also do you have a cam or head work this winter im going to do a complete head job plus a cam hop to drop more egts.

 

[FUL POWER]

What are your MPH with the Mach 6

 

[Luke Warmwater]

No head work. Saving that for next year with compounds What are the Jammer5s rated at? Let me know when you get 6s and how they compare.



Not sure I follow your last question. With 4. 10s and 35s off the top of my head I think 110mph as about it. max EGTs occur way before then though as defueling kicks in at about 2750rpm. I'm guessing max EGTs are achieved around 90-95 or so.

 

[FUL POWER]

Jammer are from 155 to 185 do you know the MPH

 

[Luke Warmwater]

155-185? How do they come up with a range? See my last post for mph.

 

[FUL POWER]

No sorry about it i was talking about MPG with the 6's and i have 355 gears
