im looking at running a set of 150s till next year when the twins gind there way under the hood. will they be to hot for daily driving till i can get the twins on .

RowJ

On which truck?...the 99 I assume. Stock injectors now? Whose 150's? Tranny still stock?

seabee

yes they are going into the 99. yes i have the borring stockers in there now and the tranny is getting done before the injectors . i have been looking at the jammer 5s i know were to get them for a good price

RowJ

With your box, I would expect 150's to be hot & smokey! JMO. No personal expirience with Jammers.

You'd be surprised how big an injector you can get away with if you have a little skinny pedal moderation.

Yes, the VA will make them smoke a little more than they otherwise might.

The injector maker you choose will be the biggest determinant. I'd only consider a small handful of 150hp sticks remotely streetable. Both of them are EDM. Then again, many people have different definitions of streetable. Some people think a tube-chassis, full-cage, hi-stall, 4.56-geared, blown big block Nova with no heat, no radio, and nothing else but HP and a thirst for race gas is "streetable". Not me.

I don't worry about high EGTs when I think of streetable. I think of smoke. If I can drive around town and not fog the road uncontrollably, then I'm happy with that.

Smoke is very controllable with the jammer 5's. You should be fine with them and a stock turbo for now, just watch the egt's.

seabee

sleds,
wich htb2 is that you have . and how bad are we talking smoke wise with these jammer stick .

JStull

My 4's have a lot more no smoke power than my old stage II honed injectors. Much better for daily driving for me. I can pull into traffic and accelerate with just about no smoke at all now.

They CAN smoke very heavy is I nail it off boost, but I have to try to do that and it is all related to the skinny pedal. I would assume 5's are just a bit worse.

Stock turbo here so far. No other issues yet. I would think you could get away with the 5's for quite a while.

Not to get side tracked...



Rowland you put down 521.2 with 150 HP Mach 4 EDM's.

Sleds you put down 571 with 150 HP jammer EDM's.

Rowland has the mad ECM/TST PM3.

Sleds has the drag comp.

Does that drag comp account for that much of a diff??

I would think the MAD ECM/TST PM3 combo would be stronger.

Both have pretty comparable turbos.

Another question??

I thought Don's new M 4's were going to be rated higher then 150 HP?




Justin

RowJ

I would not agree that the turbos are comparable. Sledpuller HTB2 has much bigger compressor, I believe.
My TST is not a comp model and while the MAD ECM is stronger on low end....at wide open throttle it does NOT add any fuel over stock.

The sledpuller has a 4mm bigger inducer wheel. The exhaust side will probably flow more than the ksb-1 also. My numbers were done on a MD2500. One thing I've always wondered is how do the company's rate their injector? Is it with a stock turbo or a large enough turbo to burn the amount of fuel delivered?

justinp20012500

Your exhaust housing would probably flow more, but with Rowland's external wg they might be very close.

Every MD 250 I have ever seen has read considerably lower then the dynojets.
