[Forrest]

no thats a bump in my pants... ... ..... :-laf

 

[DieselNasty]

Does the air go through the turbos firt or the supercharger?

 

[csutton7]

well done there PDR it would be nice to hear how it acts in a truck if you ever get that far(which it looks like may be happening)---why the 'ell the talk about lag--you guys kill me--the only time lag comes into effect any more is on the street --everyone power brakes now to get past the lag if they race on the track or sled pull and if they don't then it's their own %$^* fault---chris

 

[nascar mark]

Jeff,

Your sick. :-laf



DieselNasty,

The air is drawn in through the twin turbo's for the blower, but the blower drives the turbos before it cuts out. Bottom end is wicked, just need to work a bit on the top end. We'll get it balanced soon.



Chris,

Good to hear from you.

The air is drawn in through the twin turbo's for the blower, but the blower drives the turbos before it cuts out.

So the blower "suck starts" the turbos?





A belt driven Monica ... life is good.

Keep up the testing, Piers. The theory is sound, and may have application. I had thought of it, but glad you are trying it. Keep us all informed.



May be real good for us "thin air boys" up in Rockies.

Hell yes on the thin air boys part... and it would look pretty darn cool peeking out of the hood.

 

[willyslover]

Mark . . is that still the motor I saw with Piers under it ?? the one with the dead hole ?

 

[nascar mark]

Forrest,

Yeah, you have to like Monica. :-laf



Gary,

Nope, that is in a good friends truck of PDR.

:-laf :-laf So it sucks first then it gets blown





:-laf :--) How's that suction? Oo.

 

[jjohn]

Any updates?

Hey how did it work out ?

 

[CATCRACKER]

wow that good!?

 

[nascar mark]

As a matter of fact it works great.



Bottom end is alsome and you only give up 16hp in total but we gained 3. 6 X more hp and ftlbs at lower rpm's until 2200 rpm's were the hp caught up and 2300 rpm's for the ftlbs to catch. At 1800rpm's with a HX35 the truck made 82. 7hp and 244ftlbs. With blower and HX35 the hp was 305hp and 900ftlbs. In 100 rpm's it hit 360. 6hp and 1007 ftlbs.

Now that's useable power.

 

[RacinDuallie]

Yep, but only 2 turbo's..... right now

Mark- you mention HX-35 and the Blower- so is this a single or twin set-up here?

And you report on lower RPM hp numbers- what about the good upper numbers where you would use a setup like this at the big end of the track?

Or is this design for the street?

Seems like alot of money and work for ONLY a piddy little 350 hp... ... ... ...

Hasn't 350 hp been seen with JUST an HX-35? 400h. p. as well? (high EGT's but 400+ none the less?)

What RPM's have you seen this set-up choke off?

 

[GIT-R-DONE]

Any more pics ?

But to have over 1,000ftlbs at that low of an RPM is nuts.

Hasn't 350 hp been seen with JUST an HX-35? 400h. p. as well? (high EGT's but 400+ none the less?)

I know of one truck that hit 490+ on a stock 35. The only thing limiting it any more was the completly stock fuel system. EGT's might have been through the roof, but this was a dyno where it's all or nothing remember.

Nascar mark,

Here is some incentive for you guys to actully put it IN a vehicle:

Maybe give you some fresh ideas, different direction to go.

I see a flaw it that car's plumbing,the way it is in the pics the supercharger isn't doing anything until the turbo spools. I say this because the supercharger pulls its intake air from the I/C and the goes to the y-pipe and the y-pipe goes back to the I/C so the charger is just dumping back into its intake until the turbo spools. they need to put a butterfly in the I/C side of the Y-pipe to keep it from backflowing.
