I tested a RMF Narrow 4-1 VS a Comptech 4-2-1 today. Test motor was a ITR motor with CTR pistons, Jun3 Camshafts, Comptech Ice BOx.

These are the best of the runs between the RMF and Comptech. We tuned the Comptech, but the RMF O2 location was to far toward the collector so i could not get an accurate reading, the RMF had no tuning done, just bolt on an go. Both were done open header.

I attempted to test the Sparks, however, it WOULD NOT clear any of the AC compenents in this DC2 chassis. i removed all the ac fan, lines and it would still bump up against the Radiator fan. after about 45 min of trying to get it to fit we gave up. so it was not tested.

Thanks to TYPER76 for loaning us his car for testing.

Red is the RMF, blue is Comptech

 

wow..just imagine if u had been able too tune the rmf!!

 

another thing tho..is something wrong with that motor??its putting down like stock itr #'s with jun3's and ctr pistons..

 

The more I read on these threads the more I want to buy an RMF header.

wow, thats a big jump, even without tuning

 

Dynos in GA suck, what can i say. this is with zero cam gear adjustment as well.

 

THIS IS COMPLETELY EXPECTED.

I could never see how that version of the comp tech sold. We tested it at the "great header test" back in Dec of 2002. It did well which made me question that whole test.

That conventional 4-2-1 header (from my memory) has 1-1/2" x 1-5/8" stepped primaries (notice how much the tubes off the flange are expanded) where a usdm dc sports has 1-5/8". The comp tech has 1-3/4" secondaries just like the dc. Too bad you didn't have a comp tech race header to test, even though you already tested "one" against this header of Randy's.

I'm not trying to take anything away from Randy's header, I just wanted to give some of the spec's of that header. I believe Randy's primaries are close to the same size of those secondaries.

 

oh i hear ya. the comptech is pretty tiny.

this was SPOSED to be RMF vs Sparks. but the Sparks wouldnt fit. It fit an EG with ac, but it just wouldnt clear a DC2 chassis, it had trouble fitting over the radiator fan as well. as i said i gave up after 45min.

I will be looking for a better test car this week, i have already put the word out for an EG with no ac, half radiator so i can get some good adequate testing done. this AC **** sucks

 

so the dyno is the reason why the #'s are so low ?

 

 

no, well, it is my expierience in GA that most dynos arent as high with certain setups as you would see elsewhere in the nation.

Most STOCK itr's out here make 165whp. A ITR with bolt ons makes 170whp. remember, there is more room for power, cam gears are at zero, and all we used was a VAFC.

 

RMF does it again

 

thats a significant gain, and asswhooping. cant wait to see how my 3" rmf non compact does on my 2.1

Get outta here...you mean the owner of the test mule is running CTR pistons and Jun3 cams and just working with a VAFC!? Ouch. He has alot more coming his way. Have John set him up with Crome and turn the rollers again.

Good test, I have people still contat me now and again frothing at the mouth over Comptech headers and I have no idea why. I am going to copy this graph for future proof.

 

dang so hes just getting 10whp more outta jun3 cams and ctr pistons after being tuned?ouch oh well good test results

 

Are you going to test and compare the Toda b18 header too Vtekckidd ?

 

Mang these customed headers are just too impressive. Nice work.

 

VtecKiDD'

I have a question about the rmf header in this test so i sent you a pm.

 

Nice test

Thank you for stating this, I was also wondering why such a smallish header was being used.

&lt;------Hope people don't get this header confused with the Comptech Race Header.

 

he has an ECU chip in addition to the VAFC. we just used the VAFC to fine tune. but with the RMF, as you can see on the graph, it read 14.8 across the board because of the o2 location. i couldnt tune it or even see where it was running at.


i put the word out for a EG with no ac and and PS a a built motor locally, so i can get an adequate test done , i want to see the Sparks vs RMF vs SMSP. hopefully i can do that this weekend.

as i said it was sposed to be SParks vs RMF, but the sparks wouldnt clear. so i just went ahead and tested the comptech header to see some results. i had already pulled the comtech off, so i was like **** it, put the RMF on.

I also posted pics, if anyone thinks that comptech header is the RACE header, then thats their fault.

Signed,
Mike, who is tired of having his testing methods questioned

 

so how much are the RMF header going for?
